wear resistance

introduction:

it is a material test for measuring the ability of material to resist wear. this test can be used to compare the wear resistance of the material. the wear test is more complicated than that of the conventional material test. firstly, we need to consider the specific working conditions of parts and determine the wear form, and then the appropriate test method is selected to make the test results more consistent with the actual results. the wear model consists of adhesive wear, abrasive wear, erosion wear, corrosion wear and fretting wear.

testing standards:

gb/t 12444
