Testing Principle
During testing, standardized abrasives fall freely through the conduit under gravity from a specified height, continuously impacting the sample surface. As the test progresses, the coating gradually wears. By measuring the coating thickness or wear per unit area before and after the test, you can evaluate the coating’s abrasion resistance. This method effectively simulates particle-induced wear in real-life use.
