[PDF]Abrasion (mechanical) - Wikipedia
Abrasion resistance. Under the conditions of the test, the results can be reported or can be compared items subjected to similar tests. Such standardized measurements can produce two quantities: abrasion rate and normalized abrasion rate (also called abrasion resistance index ). The former is the amount of mass lost per 1000 cycles of abrasion.
