Description

Technical Field

[0001] The present invention relates to the technical field of material electrochemical performance testing, and in particular to a current testing device for optimizing and improving the electrochemical reaction rate of titanium aluminum single crystals. Background Art

[0002] Titanium-aluminum single crystals are titanium-aluminum intermetallic compounds with an ordered crystal structure. They combine the high strength of titanium with the lightweight properties of aluminum and are commonly used in high-temperature structural components such as aircraft engine blades. However, they are susceptible to corrosion and oxidation in service environments, affecting their performance and lifespan. Electrochemical reaction current testing can be used to evaluate their reaction rate and corrosion behavior in electrolytes, quantify their electrochemical stability, and provide a basis for material optimization and protective design.

[0003] When thin cylindrical titanium-aluminum single crystals are electrolyzed in an electrolytic cell, the electrolytic particles generated during the reaction tend to adhere to their surface, forming a coating that blocks the exposure of fresh reaction interfaces and reduces actual reaction efficiency.

[0015] Optionally, a discharge valve is provided at the bottom of the side of the recovery tank, a guide slope is symmetrically and fixedly provided in the inner cavity of the recovery tank, and a release valve is provided at the bottom of the side of the electrolytic cell.

[0016] Compared with the prior art, the present invention has the following advantages: 1. The present invention provides an inverted U-frame on the top of the electrolytic cell. The inverted U-frame is provided with an electric push rod carrying a pulling cross bar, and a variable diameter scraper assembly is provided on the side of the pulling cross bar. The scraper wire of the variable diameter scraper assembly can scrape along the outer wall of the titanium aluminum single crystal column in the electrolysis state, effectively removing the electrolytic particles or adhesion layer generated on the surface of the column during the electrolysis process.

[0018] 3. The present invention provides a synchronization component on the side of the pulling crossbar to control the position of the titanium aluminum single crystal column in the vertical direction. At the same time, a condensation release component is provided on the top of the pulling crossbar. When the electrolytic cell is installed with a new titanium aluminum single crystal column above it, the condensation release component starts to release, so that the scraping wire is in a fluffy, tension-free natural bending state, which will not form stress on the column surface. The user can easily wrap or fit the wire on the column surface. The operation is flexible and convenient, significantly improving the replacement efficiency and installation accuracy, and avoiding the scraping wire from being misplaced or scratching the surface of the new material during the installation process. After the installation is completed, when the pulling crossbar drives the titanium aluminum single crystal column to gradually sink into the electrolytic cell for electrochemical reaction, the condensation release component immediately switches to the condensation state, so that the scraping wire is tightened to the preset tension and close to the outer wall of the titanium aluminum single crystal column. This tensioning process is carried out synchronously with the sinking of the column, ensuring that the scraping wire continues to effectively adhere to the surface of the column during the entire electrolysis process, and can scrape off the attached particles produced by the reaction in real time, keep the reaction interface clean, and thus improve the stability of the current response.

[0032] Reference Figure 1-10 , a current testing device for optimizing and improving the electrochemical reaction rate of titanium aluminum single crystal, comprising a recovery pool 4, an electrolytic pool 5, and an electrochemical analyzer 53. A flip motor 1 is fixedly provided on the top of the recovery pool 4 through a top seat 2, and an electrolytic pool 5 is provided at the output end of the flip motor 1. The flip motor 1 drives the electrolytic pool 5 to flip and quickly dump the electrolyte. The top-view cross-sectional size of the recovery pool 4 is larger than the top-view cross-sectional size of the electrolytic pool 5. When the flip motor 1 drives the electrolytic pool 5 to flip, the electrolyte will not be spilled onto the ground outside the recovery pool 4. A discharge valve 3 is provided on the bottom side of the recovery pool 4. The inner cavity of the recovery pool 4 is symmetrically fixed with guide slopes 41. The two guide slopes 41 guide the waste electrolyte inside the recovery pool 4 to the discharge valve 3. A release valve 52 is provided on the bottom side of the electrolytic pool 5. The discharge valve 3 and the release valve 52 are both selected as manual butterfly valves in the prior art. In addition, the electrolytic pool 5 needs to be filled with an appropriate amount of acidic electrolyte or alkaline electrolyte according to actual needs.

[0033] Graphite electrodes 51 and titanium aluminum single crystal columns 13 are distributed along the vertical direction on the side of the electrolytic cell 5. The graphite electrodes 51, titanium aluminum single crystal columns 13, and electrochemical analyzer 53 constitute the electrolysis. The electrochemical analyzer 53 is fixedly installed on the side wall of the electrolytic cell 5. The graphite electrodes 51 and the connecting columns 143 are connected to the power terminals of the electrochemical analyzer 53 through wires. The model of the electrochemical analyzer 53 is CHI660E, which can provide power for the entire electrolysis reaction and obtain current and voltage test data.

[0034] An inverted U-frame 9 is provided on the top of the electrolytic cell 5 for sliding in the horizontal direction, and an electric push rod 10 is provided on the top of the inverted U-frame 9. The inverted U-frame 9 includes a vertical part and a horizontal part. The vertical parts of the inverted U-frame 9 are fixedly provided at both ends of the bottom of the horizontal part of the inverted U-frame 9. The bottom of the vertical part of the inverted U-frame 9 is fixedly provided on the top of the electrolytic cell 5. The specific position of the electric push rod 10 is fixedly provided in the middle position of the bottom of the horizontal part of the inverted U-frame 9, and the output end of the electric push rod 10 faces downward. A pulling cross bar 11 is provided at the output end of the electric push rod 10. The two ends of the pulling cross bar 11 are abutted against the side walls of the vertical part of the inverted U-frame 9, and a variable diameter scraper assembly is symmetrically provided on the top of the pulling cross bar 11.

[0035] A transverse screw 61 is screwed into the side of the inverted U frame 9, and both ends of the transverse screw 61 are rotatably connected to the fixed seat 7. The fixed seat 7 is fixedly set on the top of the electrolytic cell 5. The end of the transverse screw 61 is fixedly connected to the output end of the transverse motor 6. The shell of the transverse motor 6 is fixedly connected to the side of the fixed seat 7. When the transverse motor 6 is started, it will drive the inverted U frame 9 to move horizontally through the transverse screw 61, and drive the variable diameter scraper assembly at the bottom of the inverted U frame 9 to move along the outer wall of the titanium aluminum single crystal column 13. The actual length setting of the transverse screw 61 matches the length of the titanium aluminum single crystal column 13.

[0036] The scraping wire 131 in the variable diameter scraping assembly moves horizontally along the outer wall of the titanium aluminum single crystal column 13. The variable diameter scraping assembly includes the scraping wire 131, an inserted T-column 15, a limit frame 18, a horizontal spring 22 and a condensation release assembly. The material of the scraping wire 131 is titanium alloy wire to prevent the scraping wire 131 from undergoing electrolytic reaction inside the electrolytic cell 5. The condensation release assembly controls whether the scraping wire 131 is in a fluffy state.

[0037] A synchronization component is provided on the side of the pulling cross bar 11, which drives the titanium aluminum single crystal column 13 to move in the vertical direction and choose whether to enter the electrolytic cell 5. A transverse movement groove 110 is symmetrically opened on the top of the pulling cross bar 11, and a limit frame 18 is provided on the outer wall of the pulling cross bar 11. The limit frame 18 can move laterally along the outer wall of the pulling cross bar 11, and in order to reduce the transverse movement resistance of the limit frame 18, the outer wall of the pulling cross bar 11 and the inner wall of the limit frame 18 are polished into smooth surfaces.

[0038] A vertical plate 21 is fixedly provided on the side wall of the limit frame 18, and the vertical plate 21 extends into the inside of the transverse groove 110. The side of the vertical plate 21 is fixedly connected to one end of the horizontal spring 22, and the other end of the horizontal spring 22 is fixedly connected to the side wall of the transverse groove 110. The length of the horizontal spring 22 is set appropriately. When the auxiliary wheel 171 is disengaged from the control block 8 and returns to its original length, the limit frame 18 still has a certain distance from the side wall of the inverted U frame 9. When the horizontal spring 22 is at its original length, the limit frame 18 is at the closest distance to the two ends of the pulling cross bar 11.

[0039] An extension block 25 is fixedly provided at the bottom of the side of the limit frame 18, and an inserted T-pillar 15 is fixedly provided at both ends of the scraper wire 131. The front cross-section of the inserted T-pillar 15 is T-shaped. Specifically, a supporting shoulder 16 is provided on the outer wall of the inserted T-pillar 15. There is a gap between the top of the inserted T-pillar 15 and the supporting shoulder 16. The gap is used to fasten the two ends of the scraper wire 131. The inserted T-pillar 15 is movably inserted into the top of the extension block 25. A hole matching the inserted T-pillar 15 is reserved at the top of the extension block 25. An extension plate 19 is fixedly provided at the bottom of the extension block 25. The bottom of the extension plate 19 is rotatably connected to the guide wheel 20. There are two extension plates 19 in total, and the two extension plates 19 are one long and one short. Before the inserted T-pillars 15 at both ends of the scraper wire 131 are inserted into the extension block 25, the scraper wire 131 will wrap around the bottom of the guide wheel 20 after wrapping around the titanium aluminum single crystal column 13.

[0040] The condensation release assembly includes a vertical column 17, a control block 8, and a vertical spring 24. The vertical column 17 is movably inserted into the limit frame 18. A mounting block 23 is fixedly provided on the side of the vertical column 17. The bottom of the mounting block 23 is fixedly connected to one end of the vertical spring 24, and the other end of the vertical spring 24 is fixedly connected to the top of the limit frame 18. When the vertical spring 24 is at its original length, the auxiliary wheel 171 is at the highest position at the top of the limit frame 18.

[0041] The control block 8 is fixedly arranged at the bottom of the inverted U-frame 9. A guide slope 81 is provided at the bottom of the control block 8. An auxiliary wheel 171 is rotatably connected to the top of the vertical column 17. The auxiliary wheel 171 is attached to the bottom of the guide slope 81. When the electric push rod 10 retracts to a certain position, the auxiliary wheel 171 will be forced to move along the top of the guide slope 81. At this time, the two limit frames 18 approach each other, which will drive the two inserted T-pillars 15 at the top of the extension block 25 to approach, thereby loosening the scraping wire 131 directly connected to the two inserted T-pillars 15.

[0042] The synchronization component includes a synchronization rod 12, a U-shaped frame 14, and a power connection column 143. The side of the pulling cross bar 11 is fixedly connected to one end of the synchronization rod 12. The other end of the synchronization rod 12 is fixedly provided with a U-shaped frame 14. The U-shaped frame 14 is movably inserted into the shell of the electrolytic cell 5. The U-shaped frame 14 is threadedly connected to one end of the titanium aluminum single crystal column 13 inside the electrolytic cell 5. A vertical groove 141 is provided on the side wall of the U-shaped frame 14. A guide block 142 is fixedly inserted into the vertical groove 141 along the vertical direction. The guide block 142 is fixedly connected to the outer wall of the electrolytic cell 5. The guide block 142 assists the U-shaped frame 14 to move stably in the vertical direction. Finally, in order to prevent the U-shaped frame 14 from being corroded by the electrolytic cell 5, the material of the U-shaped frame 14 is selected to be plastic.

[0043] The specific implementation steps and principles of the present invention are as follows: Start installing a new titanium aluminum single crystal column 13 from the electrolytic cell 5. At this time, the electrolytic cell 5 is in a horizontal state, the inside of the electrolytic cell 5 is filled with acidic electrolyte or alkaline electrolyte, and the electric push rod 10 is in a retracted state. At this time, the auxiliary wheel 171 contacts the higher position of the guide slope 81 at the bottom of the control block 8, and the vertical spring 24 is compressed. At this time, the two limit frames 18 are close to each other by a certain distance, and the two horizontal springs 22 are compressed to a certain extent. After the user screws the titanium aluminum single crystal column 13 into the side thread of the U-shaped frame 14, he inserts one end of the hand-held scraping wire 131 into the T-column 15, and Figure 5 A circle of scraping wire 131 is wrapped around the outer wall of the titanium aluminum single crystal column 13, and then both ends of the scraping wire 131 are wrapped around the guide wheel 20, and then the inserted T column 15 is reinserted into the top of the extension block 25.

[0044] When the electrolysis of the titanium aluminum single crystal column 13 begins, the electric push rod 10 extends, and on the one hand, it pulls the cross bar 11 and the synchronous rod 12 to drive the U-shaped frame 14 to move downward, so that the titanium aluminum single crystal column 13 on the side of the U-shaped frame 14 sinks into the electrolyte inside the electrolytic cell 5 until the titanium aluminum single crystal column 13 is submerged. At this time, the auxiliary wheel 171 separates from the guide slope 81 at the bottom of the control block 8. Since the titanium aluminum single crystal column 13 has a certain diameter, the horizontal spring 22 recovers a certain length but does not return to its original length. Long, the vertical spring 24 returns to its original length, and the two limit frames 18 move away from each other, straightening the scraper wire 131, and finally starting the transverse motor 6. The transverse motor 6 drives the transverse screw 61 to rotate, driving the inverted U-frame 9 to move transversely along the top of the electrolytic cell 5, and the scraper wire 131 continuously scrapes off the particles produced by electrolysis on the outer wall of the titanium aluminum single crystal column 13. As the diameter of the titanium aluminum single crystal column 13 gradually shrinks during the electrolysis process, the horizontal spring 22 gradually returns to its original length, keeping the scraper wire 131 taut.

[0045] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
