Abstract
A simple melt infiltration process was adopted to form Ti3Si(Al)C2 on the surface of SiC ceramics. The Ti3Si(Al)C2 content increases with longer infiltration at 900â¯Â°C. At 1000â¯Â°C, the reaction layer contains mainly TiC and SiC. The tribological properties of the samples were investigated by wear testing. The hardness of the SiC ceramic with a Ti3Si(Al)C2 layer is 610â¯Â±â¯82 HV, while its friction coefficient is 0.34-0.38, which is â¼75% that of pristine SiC. The Ti3Si(Al)C2 layer produced a good antifriction effect because plastic deformation occurs in the Ti3Si(Al)C2, and Ti3Si(Al)C2 debris continually fills in the grooves during wear.
