Abstract

The aim of this research is to provide an explanation of the sliding wear mechanism in the tilted contact between a block and flat surface through experiment and logical analysis. For this purpose, the authors first used a CCD microscope tribosystem, and conducted sliding wear experiments modeling the tilt of an S 45 C block test piece with various types of metal plates (aluminum alloy, S 45 C) with base oil lubrication. As a result, they were able to classify the wear modes under tilted contact as "cutting," "ploughing," and "plastic deformation of the block tip." The authors also conducted a logical analysis of the regions in which these wear modes occur, and constructed a wear map using the attack angle and hardness ratio of both materials on the two axes with the dimensionless interfacial shear strength which expresses the degree of lubrication state as a parameter. It was confirmed that the region of wear mode occurrence observed in experiments nearly conformed with the wear map.
