Friction and Wear Properties of the Al2O3-TiC-TiN Composite Ceramic under Single Abrasive
单磨粒作用下Al2O3-TiC-TiN复合陶瓷的摩擦磨损特性

With the help of an in-situ pin-disk sliding wear apparatus in scanning election microscopes (SEM), the friction and wear properties of the Al2O3-TiC-TiN advanced composite ceramic under single abrasive were studied. The results show that the friction behaviors of Al2O3-TiC-TiN have different characteristics in vacuum and air. At first the dominant wear mechanism is the microcutting and with the wear proceeding the brittle fracture becomes more and more important. The experiments also indicate that the relative hardness of the abrasive has a great effect on the wear rate of this material under three-body abrasion conditions.
