| 摘 要： | 采用热压烧结方法制备了氧化铝／碳化钛复合陶瓷，对材料的摩擦因数和磨损率进行测量，研究了AlTiC中间合金增韧补强氧化铝陶瓷摩擦磨损行为与机制，探讨了氧化铝基精密结构陶瓷的摩擦磨损特性以及力学性能和微观结构对摩擦磨损特性的影响。结果表明，在室温和干摩擦条件下，滑动摩擦因数随法向载荷和转速的增加有下降趋势，室温下新型氧化铝基复相陶瓷材料的磨损机制以微观切削为主。

| Abstract: | Al2O3/TiC composites are sintered by hot-pressing process. The friction coefficient and wear rate of the composites are measured. Friction and wear performance of alumina matrix ceramic materials, which were reinforced by AlTiC, are investigated. Effects of mechanical properties and microstructure on friction and wear performance are also researched. The results showed that, the gliding friction coefficient of Al2O3/TiC composites decreased with the increasing of rotate speed. Wear mechanism of the new alumina matrix ceramic composites was mostly micro-machining at room temperature. |
