The velocity-dependent wear behaviors of a phosphate laser glass were investigated by a reciprocating sliding tribometer in dry and humid air. The experimental results show that, with increase in sliding velocity, the wear volume of phosphate glass increases in dry air but decreases in humid air. Adhesive wear occurs easily in the high velocity sliding due to the friction-induced high temperature. Under low velocity, the absorbed water film between the contact asperities forms more easily, and the tribochemical reaction is more sufficient, which assists the material removal of phosphate glass.
