Abstract

Pin-on-disk wear tests have shown that oxygen is a significant factor in the wear of both silicon nitride-and tungsten carbide-based tool materials against common iron-based alloys such as cast iron and steel. It was not expected that pin-on-disk wear tests could be related to tool wear in machining processes because the mechanical processes involved were different. However, it was found that if speeds, pressures, and environments were the same, there were surprisingly good correlations between the pin-on-disk tests and machining operations such as turning and boring.
