Abstract

The non-lubricated, ball-on-flat sliding friction and wear properties of in situ (TiB₂+TiC)/Ti₃SiC₂ composites against bearing steel ball were investigated. The load was varied from 10 to 30N. The material without TiB₂ shows an increasing friction coefficient with the increasing load. However, for (TiB₂+TiC)/Ti₃SiC₂ composites, the friction coefficient shows an insensitivity to load. Both friction coefficient and wear rate initially increase and then dramatically decrease with TiB₂ content increasing from 0 to 20vol%. (TiB₂+TiC)/Ti₃SiC₂ composites with 15vol% and 20vol% TiB₂ show excellent wear resistance, whose friction coefficient and wear rate are much lower than those of TiC/Ti₃SiC₂ composite. The enhanced wear resistance is mainly attributed to the facts that the hard TiB₂ and TiC particles nail the surrounding soft matrix and decentralize the shear stresses under the sliding ball, a self-lubricating oxide debris forms on the wear surface, and the wear mode converts from adhesive wear to abrasive wear.
