Fundamental Tribomechanics at Severe Contact Conditions

该研究项目的重点是分析陶瓷和金属陶瓷表面在高温和大接触应力下的基本摩擦和磨损机制。根据实验和分析结果，重点将放在检查摩擦学性能对一些关键参数的依赖上，如陶瓷层的厚度、温度、表面牵引力的大小、界面“摩擦”条件以及层和基板材料的机械和热性能。对受机械和热表面载荷作用的层状介质进行有限元分析，结合实验工作，将为设计用于严重接触应用的低摩擦和耐磨层状表面制定必要的标准。

The thrust of the research program is on the analysis of the fundamental friction and wear mechanisms of ceramic and metal-ceramic surfaces subjected to high temperatures and large contact stresses. Particular emphasis will be placed on examining the dependence of the tribological properties on some critical parameters such as ceramic layer(s) thickness, temperature, magnitude of surface tractions, interfacial "friction" conditions, and mechanical and thermal properties of layer and substrate materials, in the light of experimental and analytical results. The finite element analysis of layered media subjected to mechanical and thermal surface loads, in conjunction with the experimental work, will result in the development of the necessary criteria for the design of low-friction and wear- resistant layered surfaces for severe contact applications.
