Wear of Fluorapatite Single Crystals : V. Influence of Environment on Frictional Behavior and Surface Failure

Abstract

The influence of environment on the frictional behavior and surface failure of fluorapatite single crystals was evaluated for sliding in air, water, and dimethylformamide. The coefficient of friction was independent of environment. The ductile-to-brittle transition, however, occurred at a lower load in water than in air.
