Stress analyses of New Al2O3-based ceramic materials against cemented carbide during wear process
Finite element model was established by using ANSYS software to get the stress distribution of Al2O3-based ceramic materials (pure Al2O3、Al2O3/TiC、Al2O3/(W,Ti)C、Al2O3/Ti(C,N)和Al2O3/SiCw ) against cemented carbide during high-speed ring-block wear process. Results showed that there is a great difference between the maximum of main stress and shear stress for the Al2O3-based ceramics with different additives. The maximum of main stress is located at the center of sliding couple, while the maximum of shear stress is at the outside of sliding couple. The value of the stress increases with the increase of applied load, and the sliding speed has little effect on the stresses. Under the same working condition, the wear rate of ceramic materials increases with the increase of stress. If the stress during wear process is large enough, micro-crackles will appear on the surface of ceramic.
