This document describes a procedure for conducting ball cratering tests to determine the abrasion resistance of thin hard coatings. In the test, a ball is rotated and is pressed against the sample until a spherical depression is produced. By making a series of these craters and measuring the size of the scar dimensions, the wear rate of both the coating and the substrate can be calculated.
