[0040] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0041] In the description of the present invention, unless otherwise expressly specified or limited, the terms "connected," "connected," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific circumstances.

[0042] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Furthermore, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0043] In the description of this embodiment, terms such as "upper," "lower," and "right" are used to refer to positions or locations based on the positions or locations shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.

[0044] like Figures 1-9 As shown, this embodiment provides a corrosion testing system, for example, for simulating corrosion testing in extremely low-temperature marine environments. The corrosion testing system includes a support frame 11, a housing 12, a corrosion plate 13, a water supply and drainage device 14, a water storage device 15, a fixing assembly 16, an electrode assembly 17, a water injection device 18, a potentiostat 19, and a controller. The housing 12 and corrosion plate 13 are both mounted on the support frame 11, with the corrosion plate 13 located within the housing 12. The water supply and drainage device 14 is used to supply and drain water from the housing 12. The water storage device 15, the fixing assembly 16, the electrode assembly 17, and the water injection device 18 are all disposed on the corrosion plate 13. The water storage device 15 has a first operating position and a second operating position and can be switched between the first and second operating positions. The fixing assembly 16 is used to secure the test specimen 100, and the water injection device 18 is used to inject water into the water storage device 15. When the water storage device 15 is in the second operating position, the test specimen 100 and the electrode assembly 17 are at least partially located below the current maximum liquid level of the water storage device 15. When the water storage device 15 is in the first operating position, the test specimen 100 and the electrode assembly 17 are located above the current maximum liquid level of the water storage device 15. The potentiostat 19 is electrically connected to the electrode assembly 17, specifically via a circuit. The water supply and drainage device 14, the water storage device 15, and the water injection device 18 are all communicatively connected to the controller. Those skilled in the art will appreciate that the water storage device 15 has different maximum liquid levels when it is in the first working position and when it is in the second working position, and the maximum liquid level when the water storage device 15 is in the second working position is higher than the maximum liquid level when the water storage device 15 is in the first working position.

[0045] The corrosion testing system provided in this embodiment injects water into the housing 12 via the water supply and drainage device 14, causing the housing 12 to contain a certain amount of water. This simulates a marine environment within the housing 12 and tests the corrosion of the specimen 100 in this environment. During the test, the water storage device 15 can be controlled to move from a first working position to a second working position as needed, and a certain amount of water can be injected into the water storage device 15 via the water injection device 18, so that the specimen 100 and the electrode assembly 17 come into contact with the water in the water storage device 15 to measure the degree of corrosion. After the measurement is completed, the water storage device 15 is controlled to move from the second working position to the first working position, at which point the specimen 100 is no longer in contact with the water in the water storage device 15, and the simulation of the corrosion process of the specimen 100 continues. In the corrosion testing system provided in this embodiment, both the corrosion process of the specimen 100 and the corrosion degree measurement process are automatically performed within the housing 12, resulting in high test efficiency and convenient control of the corrosion environment throughout the entire experimental process.

[0046] The electrode assembly 17 in this embodiment includes a reference electrode 173, a working electrode 171, and an auxiliary electrode 172. The reference electrode 173, the working electrode 171, and the auxiliary electrode 172 are all electrically connected to a potentiostat 19. When the water storage device 15 is in the second operating position and the water injection device 18 injects water into the water storage device 15, the reference electrode 173, the working electrode 171, and the auxiliary electrode 172 all come into contact with the water in the water storage device 15. The electrode assembly 17 transmits the corrosion electrical signal to the potentiostat 19 via a circuit, and the corrosion rate of the specimen 100 is measured using the corrosion potential difference. In this embodiment, the reference electrode 173 is a saturated calomel electrode, and the auxiliary electrode 172 is a platinum sheet. The further principles of material corrosion testing using the potentiostat 19, the reference electrode 173, the working electrode 171, and the auxiliary electrode 172 are common knowledge in the art and will not be elaborated upon here.

[0047] Optionally, the corrosion testing system provided in this embodiment further includes a first drive device, which is disposed on the support frame 11 and is configured to drive the corrosion plate 13 to rotate relative to the housing 12 about a first axis extending horizontally. The first drive device is communicatively connected to a controller. During the test, the water level within the housing 12 can be raised above the bottom of the vertically positioned corrosion plate 13. The first drive device then drives the corrosion plate 13 to rotate about the first axis parallel to the horizontal direction, causing the corrosion plate 13 to cause the water within the housing 12 to surge, simulating the effect of splashing waves and thereby simulating the corrosion of the test specimen 100 under the waves.

[0048] Alternatively, as Figure 3 、 Figure 6 、 Figure 7 and Figure 8As shown, the water storage device 15 includes a housing 151 and a second drive device 152. The second drive device 152 is disposed on the corrosion plate 13 and connected to the housing 151. The second drive device 152 is used to drive the housing 151 to switch between a first working position and a second working position relative to the water storage device 15. The second drive device 152 is communicatively connected to a controller, which controls the switching of the water storage device 15 between the first and second working positions. In this embodiment, the second drive device 152 is disposed at both ends of the housing 151 in the longitudinal direction. The housing 151 and the second drive device 152 enclose a water storage chamber.

[0049] Furthermore, if Figure 3 、 Figure 6 、 Figure 7 and Figure 8 As shown, the second drive device 152 can drive the housing 151 to rotate relative to the corrosion plate 13 to switch the water storage device 15 between the first working position and the second working position. The rotation axis between the housing 151 and the corrosion plate 13 is parallel to the first axis, which is also parallel to the horizontal direction. The rotation of the water storage device 15 relative to the corrosion plate 13 changes the maximum liquid level of the water storage device 15. In this embodiment, the second drive device 152 is a small waterproof roller motor.

[0050] Alternatively, as Figure 2 、 Figure 3 and Figure 7 As shown, a plurality of water storage devices 15 are provided, and the fixing assembly 16, the electrode group 17, and the water injection device 18 are all provided in a one-to-one correspondence with the water storage device 15. The plurality of water storage devices 15 are spaced apart in a direction perpendicular to the first axis. When the corrosion plate 13 is in a vertical state, the plurality of water storage devices 15 are spaced apart in the vertical direction. In other words, the test specimens 100 fixed on the fixing assembly 16 corresponding to the water storage device 15 are also spaced apart in the vertical direction. During the corrosion test, the water level in the box 12 can be controlled according to the test requirements, and the corrosion plate 13 can be driven to rotate about the first axis by the first driving device, so that some of the plurality of test specimens 100 on the corrosion plate 13 are completely immersed, some are alternately wet and dry, and some are completely exposed to the air, thereby testing three different corrosion conditions in one test, thereby improving the test efficiency.

[0051] In this embodiment, if Figure 2-Figure 4As shown, the fixing assembly 16 includes a plurality of fixing members 161 spaced apart and arranged parallel to the first axis. The test specimens 100 are fixed to the fixing members 161, and each fixing member 161 is capable of fixing a single test specimen 100. In other words, during the corrosion test, multiple test specimens 100 can be mounted corresponding to each water storage device 15. When the water storage device 15 corresponding to the fixing assembly 16 is in the second operating position and filled with water, the multiple test specimens 100 fixed to the fixing assembly 16 are in contact with the water within the water storage device 15. The specific structure of the fixing member 161 can be configured as needed, as long as it can achieve both fixing and removal of the test specimens 100.

[0052] Alternatively, as Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 and Figure 8 As shown, an opening 153 extending along the first direction is provided at the top of the water storage device 15, and a mounting portion 131 corresponding to the water storage device 15 is provided on the corrosion plate 13. The fixing assembly 16 is provided on the corresponding mounting portion 131. When the water storage device 15 is in the second working position, the mounting portion 131 extends into the corresponding water storage device 15 through the opening 153, so that the water storage device 15 is in the second working position and the water injection device 18 injects water into the water storage device 15. Then, the test piece 100 and the electrode group 17 on the corrosion plate 13 can contact the water in the water storage device 15.

[0053] Furthermore, if Figure 2-Figure 5 As shown, the corrosion plate 13 is provided with mounting holes 132 corresponding one to each water storage device 15. The water storage device 15 is disposed in the corresponding mounting hole 132. The top end of the mounting portion 131 is fixed to the top wall of the corresponding mounting hole 132, and the bottom end extends into the corresponding mounting hole 132. When the water storage device 15 is in the second working position, the water storage device 15 is in a horizontal position. When the water storage device 15 is in the first working position, the water storage device 15 is in an inclined state.

[0054] Alternatively, as Figure 1 and Figure 2 As shown, the support frame 11 includes a base 112 and a support arm assembly 111. The support arm assembly 111 includes two opposing support arms 1111, both of which are fixedly mounted on the base 112. The etching plate 13 is rotatably connected to the two support arms 1111 at both ends along the first direction, and the housing 12 is fixedly connected to the two support arms 1111 at both ends along the first direction. The rotational connection between the etching plate 13 and the support arms 1111, as well as the provision of a first drive device within the support arms 1111 to drive the etching plate 13 to rotate relative to the support arms 1111, are conventional techniques in the art and will not be described in detail here.

[0055] Alternatively, as Figure 1As shown, the corrosion test system provided in this embodiment further includes a water level monitoring device 20 provided on the box body 12 , and the water level monitoring device 20 is used to monitor the water level in the box body 12 to ensure that the water level in the box body 12 meets the test requirements.

[0056] Alternatively, as Figure 1 As shown, the corrosion test system provided in this embodiment further includes an ultraviolet lamp 21, which is mounted on the housing 12 and is used to irradiate ultraviolet light into the housing 12. Since polar regions are covered in ice, ultraviolet light is strongly reflected. Therefore, the corrosion test system in this embodiment is equipped with an ultraviolet lamp to simulate the effects of ultraviolet light on corrosion in polar ocean regions.

[0057] Alternatively, as Figure 1 As shown, a box cover 121 is rotatably provided on the top of the box body 12, and a handle 123 is fixedly provided on the box cover 121. The box body 12 is also provided with an observation window 122, and a window panel for covering the observation window 122 is slidably provided at the observation window 122. In this embodiment, the observation window 122 is provided on the box cover 121.

[0058] Alternatively, as Figure 1 As shown, the water supply and drainage device 14 includes a water inlet pipe 142, a drain pipe 143 and a water pump 141. The water pump 141 is arranged on the water inlet pipe 142. The water inlet pipe 142 and the drain pipe 143 are both connected to the inner cavity of the box body 12. The water pump 141 cooperates with the water inlet pipe 142 to supply water to the box body 12, and the drain pipe 143 is used to drain the box body 12.

[0059] The corrosion test process of the corrosion test system provided in this embodiment is as follows:

[0060] Open the box cover 121 and place the test piece 100. Specifically, hold the handle 123 of the box body 12, open the box cover 121, and place the test piece 100 to be tested on the fixing member 161. Close the box cover 121 and set the control program of the controller.

[0061] The controller controls the water pump 141 to inject water into the box 12 according to the control program, and the water level monitoring device 20 monitors the water level in the box 12. After the water level in the box 12 reaches the preset water level, the controller controls the water pump 141 to stop injecting water. According to the test program, the controller controls the corrosion plate 13 to swing around the first axis to simulate the wave effect and controls the ultraviolet lamp 21 to irradiate ultraviolet rays into the box 12 to simulate the ultraviolet environment of the polar ocean, etc., so as to control the corrosion environment; controls the water storage device 15 to switch between the first working position and the second working position and controls the water injection device 18 to inject water into the water storage device 15, etc., so as to make the specimen 100 circulate in both dry and wet states and monitor the corrosion rate. It should be noted that the dry state is the state in which the specimen 100 is not in contact with the water in the water storage device 15. This state is a normal corrosion state. The wet state is the state in which the specimen 100 is partially or completely immersed under the water surface in the water storage device 15. This state is a corrosion degree measurement state. The corrosion degree of the specimen 100 is measured multiple times during the corrosion test to determine the corrosion rate of the specimen 100 in each stage of the corrosion test.

[0062] After the test is completed, the water supply and drainage device 14 drains the water in the box 12.

[0063] The corrosion testing system provided in this embodiment can simulate the effects of ocean waves and ultraviolet rays on the corrosion of the specimen 100. Furthermore, the corrosion process of the specimen 100 and the corrosion rate measurement process are both automatically performed within the box 12, resulting in high test efficiency and more reliable test results.

[0064] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
