High speed face milling for plain carbon steel S 45 C was carried out with ceramic tools. TiC added alumina, and zirconia toughened alumina ceramic tools were mainly used. Among the tested ceramic tools, the zirconia toughened alumina ceramic tool showed the largest crater wear resistance in high speed face milling. However, in turning the same steel, the crater wear resistance of the ceramic tool was almost the same degree as compared to the other ceramic tools. The superior wear resistance of the zirconia toughened alumina ceramic tool is based on its stability for the reaction with Fe0 at high temperature.
