Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0020] Please refer to Figures 1-5 The utility model provides a technical scheme:

[0021] Aerospace-grade vanadium-aluminum alloy corrosion detection equipment, including test box body 1, test box body 1, test box body 1 sample place area inside both sides are fixedly connected with inner supporting seat 16, the top left side of test box body 1 is rotatably connected with perspective machine cover 2, the inner side lower position of perspective machine cover 2 is equipped with lower supporting plate 3, the bottom end both sides of lower supporting plate 3 are fixedly connected with and the side buckle plate 4 of bolt detachable connection of perspective machine cover 2, the top center position of lower supporting plate 3 is equipped with upper expansion ring 5, the bottom center position of lower supporting plate 3 is equipped with lower expansion ring 6, the inner side of lower expansion ring 6 is equipped with salt spray head body 7, the surface of lower supporting plate 3 is equipped with mist outlet 8, the position directly below mist outlet 8 is equipped with sample holder 14 that overlaps the position above inner supporting seat 16, the top both sides of lower supporting plate 3 are fixedly connected with inclined strut 9, and the top end of inclined strut 9 is fixedly connected with upper supporting plate 10.

[0022] As Figure 1 Shown, the front end surface lower position of test box body 1 is equipped with discharge plug 17, and the front end right side of test box body 1 is equipped with controller 18, and the top right side of test box body 1 is equipped with supplementary valve cover 19, after completing corrosion detection operation, can open discharge plug 17, and make the remaining salt water in salt water tank 20 to discharge outward.

[0023] As Figure 1 ,Figure 2 , Figure 3 and Figure 5 As shown, the upper part of the fluoroscopy cover 2 is conical. A saline tank 20 is located at the lower part of the test chamber body 1. The water inlet below the replenishment valve cover 19 leads directly into the saline tank 20, which facilitates the addition of clean water or hydrochloric acid solution into the saline tank 20. The lower part of the salt spray nozzle body 7 is located at the upper part of the test chamber body 1. The salt spray nozzle body 7 passes through both the lower support plate 3 and the upper expansion ring 5. The front end of the sample holder 14 is adjacent to a collector 15 located inside the test chamber body 1. The upper part of the collector 15 is funnel-shaped. The collector 15 and the saline tank 20 are connected. When the mist erodes and adheres to the sample, the collector 15 collects the mist.

[0024] Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the connection between the lower support plate 3 and the two side fasteners 4 forms a "U" shaped structure. The left and right sides of the upper support plate 10 are tightly fitted to the inner side of the fluoroscopy cover 2. A motor 11 is fixedly installed on the top of the upper support plate 10. The output end of the motor 11 passes through the interior of the upper support plate 10 and is fixedly connected to an adapter 12. A support rod 13 is fixedly connected to the outside of the adapter 12. Several support rods 13 are arranged between the upper support plate 10 and the lower support plate 3. Several mist outlets 8 are arranged equidistantly along the horizontal direction opposite to the sample holder 14. The top surface of the sample holder 14 is provided with a conical groove structure. When the mist diffuses out, the turbulence structure composed of the upper support plate 10, the motor 11, the adapter 12, and the support rods 13 will turbulently process the mist, making the mist diffusion more uniform.

[0025] Workflow: The electrical energy required for the start-up and operation of the testing equipment in this utility model comes from an external power source. Before using the equipment, the replenishment valve cover 19 can be opened to inject an appropriate amount of clean water and prepared hydrochloric acid solution into the saline tank 20. Combined with the pre-aligned mist discharge hole 8, the sample holder 14 is placed on the upper part of the two inner supports 16, so that it is installed inside the test chamber body 1. When it is necessary to use this corrosion testing equipment to perform corrosion testing on aerospace-grade vanadium-aluminum alloy materials, first open the fluoroscopy cover 2 outward so that the lower support plate 3, upper expansion ring 5, and lower expansion ring 6 are separated from the salt spray nozzle body 7. Place the vanadium-aluminum alloy sample, which has been pre-cut into small pieces, flat on the sample holder 14. Then, flip and adjust the fluoroscopy cover 2 to close it. At this time, with the synchronous flipping action, the salt spray nozzle body 7 will reconnect with the lower support plate 3, upper expansion ring 5, and lower expansion ring 6 through a centering insertion method. With rings 6 connected together, the mist exhaust range of the salt spray nozzle body 7 can be limited to between the lower support plate 3 and the upper support plate 10. Then, the entire device is started, and the heated salt water is carried out from the inside of the salt spray nozzle body 7 in the form of mist. The mist will spread between the lower support plate 3 and the upper support plate 10. At the same time, the motor 11, which is in operation, will rotate through the adapter 12 and the support rod 13 to uniformly disturb the mist that has spread between the lower support plate 3 and the upper support plate 10, making the mist diffusion more uniform. Then, the mist will be sprayed evenly onto the sample above the sample holder 14 through the interior of the multiple mist discharge holes 8, so that the mist can uniformly corrode and adhere to the sample, improving the accuracy of the sample detection. Finally, after several hours of mist corrosion treatment, the X-ray machine cover 2 can be opened to remove the sample and observe the current corrosion status of the sample surface, thereby evaluating the corrosion resistance of the sample.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
