莫来石纤维含量对陶瓷基摩擦材料摩擦磨损性能的影响
Effects of Mullite Fiber Content on Friction and Wear Properties of Ceramic-based Friction Material
摘要
Abstract
Ceramic-based friction material with 0%-24% (mass fraction) mullite fiber reinforcement was prepared by nitrogen protection hot-pressing sintering. The effect of mullite fiber content on friction and wear properties of ceramic-based friction material was studied on the XD-MSM constant speed friction tester. The worn surfaces morphology after tests was observed by scanning electron mic'rosco-py (SEM), and wear mechanism was discussed. The results show that mullite fiber could increase friction coefficients of ceramic-based friction material, and with increasing mullite fiber contents, friction coefficients continuously increase. While the wear rates also increase with increasing mullite fiber contents at high temperature. The dominant wear mechanism of ceramic-based friction material without mullite fiber is brittle spalling and fatigue wear, accompanying with abrasive wear; the main wear type converts into adhesion wear and abrasive wear when adding mullite fiber into ceramic friction material.关键词
