Surface engineering design: modelling surface engineering systems for improved tribological performance

摘要

Rapid developments in surface engineering technologies have made available many surface engineering systems to combat diverse component degradation problems and to meet the ever-increasing demands for combined properties in modern machineryoperating under ever more severe conditions. Designers thus have many surface engineering technologies to select from in the design of components. Therefore, design methodology is urgently required for surface engineering to assist engineers in theirdesign of components with the surface and substrate as a system. The present paper attempts to highlight recent developments in this area and to discuss the philosophy behind building such a design methodology through several case studies, including areal-rough surface contact model to simulate the elastic contact behaviour of multi-layer systems and a finite element model to predict the plastic deformation behaviour of the surface, subsurface and interfacial region.
