摘要：Great heat will generate in turning difficult-cut materials with Al2O3 ceramic tools, cutting temperature always highly reaches over to 1000°c during high speed machining. 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 calculated. Diffusion reaction rules in high temperature are also analyzed using Gibbs free energy criterion, it was found that the theoretical results were uniform with the experimental data; and the diffusion solubility of Al2O3 ceramic tools is usually much smaller. The order of dissolution of Al2O3 ceramic tools in machining several typical normal workpieces is as follows: titanium nickel steel, At the same cutting condition, when machining cast iron and 35# steel, the wear performance of tools is very different and the wear mechanism should be researched more. The results will provide useful references for tool material design and selection. ? 2018 Indian Pulp and Paper Technical Association. All rights reserved.
