Outline of Final Research Achievements

Adhesive substances which fixed on the sliding surface in very early stage of sliding are known to govern the phenomena of oil lubricated sliding for long-term. An attempt was made to elucidate influencing factors on the fixture location of the adhesive substances and the size of the substances at the time of the fixture. Surface roughness and residual stress as the pre-sliding influencing factors and impulse load as an in situ influencing factor were looked into. Surface roughness and residual stress on the metallic surface enhanced the growth of an adhesive substance on the surface of a constantly sliding body and prevented the substance to transfer to its counterpart. The impulse load while sliding did no influences on the adhesion and transfer of materials. Some possibility to control the generation, growth and fixture of adhesive substance was suggested.
