[0002] In the application process of anti-corrosion materials, they are inevitably subject to various forms of friction and wear, which may affect their anti-corrosion effect and service life. Therefore, wear resistance is one of the important parameters to measure the actual application effect of anti-corrosion materials.

[0003] There are many ways to test the wear resistance of anti-corrosion materials, such as the reciprocating friction test method and the microscope observation method. The reciprocating friction test method mainly places the sample in the test area and drives the friction block to reciprocate on the sample surface through a driving device to test the durability and wear degree of the material under repeated friction.

[0004] At present, when testing the wear resistance of anti-corrosion materials, most samples are placed on a table and rubbed back and forth on their surfaces by a friction block. After completing the friction test on one side, the sample is turned over and the other side is tested for wear resistance.
