Research Abstract

In order to evaluate the tribological characteristic and peformance of high functional modified surface, the comprehensive experiment and analysis were performed under high temperature in high vacuum.
Kinds of high functional sliding materials were wear-tested under high temperature in high vacuum and the information of their ability were obtained.
In order to clarify the influence of surface modification on rolling contact fatigue strength the surface modified rollers were fatigue-tested and their contact pressure and subsurface stresses were analysed with the boundary element method. The reason why the improvement of rolling contact fatigue strength by surface modifications would be due to the reduction of contact pressure and subsurface stresses.
Various electroless Ni platings were wear-tested with a two-cylinder test machine and the influence of dispersed particles in the plated layer on friction and wear behaviors was investigated with the finite element method analysis. When the elastic modulus of the dispersed particles is smaller than that of the matrix, the maximum shear stress and Mises stress around the dispersed particles become large, resulting in wear increasing. It was indicated how to decide the optimum particle size.
Fractal dimensions of various worn surfaces were analysed with data measured with a profile meter and a laser-scanning microscope, and applied to the evaluation of worn surface. It was obvious that the more beneficial information could be obtained using fractal dimensions analysed with both instruments.
