The reference abrasion-resistance test for organic and anodic coatings using a Taber abraser instrument. Standard wheel pairs are CS-10 (mild abrasion) and CS-17 (severe abrasion). Mass loss per 1000 cycles is reported. Properly run hard anodize on 6061 substrate typically shows 1.5-3.5 mg loss per 1000 cycles with CS-17 wheels — a key QC checkpoint for tribological applications.
