Tribological properties of five glass‐ceramics are reported. The materials were tested unlubricated against themselves. Testing was performed using a simulated inertial sample dynamometer. Sliding speeds were between 0.5 and 1.8 m /S with an applied load of 225 N. Average friction coefficients were in the range 0.07 to 0.5. The wear rate of a lithium aluminosilicate was 43 ×10–14 m3/N.m, in good agreemen2 with previous pin‐on‐disk results. Wear surfaces exhibited cracking, ploughing, delamination, and viscous flow or plastic deformation.
