... reflectance. The selection of variables to measure wear is often based on convenience, the nature of the wear specimens, available techniques, and the amount of wear. Material wear behavior can be compared by determining a wear curve or measuring wear at a single point in the test. Wear behavior frequently...

... stress/true strain curve ( Ref 157 ). As such, plasticity indexes or strain-hardening coefficients can correlate with the tendency of a material to exhibit adhesive wear. This concept suggests that brittle ceramics do not plastically deform like metals, and thus, they should be less prone to adhesive...
