A relationship between microstructure and the tribological properties of apatite-wollastonite glass-ceramics (A-W GC), fabricated by different techniques of melt casting and powder packing processing, was studied. The surface crystallisation of wollastonite caused a unique surface strengthening in an A-W GC prepared by the melt casting process. The wear rate did not vary between the free surface and interior in an A-W GC made by powder packing, whereas an increase of the wear rate with an increase in the distance from the free surface was detected in an A-W GC fabricated by melt casting. However, the melt casting process resulted in a higher wear resistance in A-W glass-ceramics for prosthetic applications. 11 refs.
