The two-dimensional vertical grinding test equipment was used to grind
SiCp/Al composites which were prepared by high pressure sintering
method. The SEM observation of grinding morphology showed that grinding
damage can be prevented by SiC particles reinforcement, 60% volume
fraction of SiC particles of SiCp/Al composite can hinder grinding depth
and grinding performance was improved with the sintering pressure and
temperature increasing. In addition, some scratches and exfoliated pits
of SiC particles were observed on the surface of 60% volume SiCp/Al
composite as the increase of grinding grain, while the depth of these
scratches was shallower, there was no large area exfoliated pits of SiC
reinforcements.<br>
