1.1 This test method quantifies the abrasion resistance of metallic coatings produced by thermal spray processes on flat metallic surfaces. It is intended as a means of characterizing coatings used on surgical implants.1.2 This test uses the Taber Abraser, which generates a combination of rolling and rubbing to cause wear to the coating surface. Wear is quantified as cumulative mass loss.1.3 This test method is limited to flat, rigid specimens that do not react significantly wit
