The cutting temperature always reaches over 1000degC during high speed cutting with Al2O3 ceramic tools. Diffusion wear is the main wear mechanisms at such high temperature. In this paper, the rules of diffusion wear for Al2O3 ceramic tools are studied based on thermodynamics. Dissolution concentrations in typical normal workpiece materials of ceramic tool material at different temperature are then...
For hardness measurements, the indentation depth is about 10% of the effective information depth under static loading. A change of the wear mechanism is observed under lateral loading conditions in oscillating ball-on-disc tests for nitrided austenitic stainless steel with an expanded austenite surface layer from abrasive to a subsurface plastic flow with a redistribution of the inserted nitrogen...
