      摘 要:研究TC4合金在氯化钠溶液中的微动磨损行为,分析不同摩擦副材料下载荷与磨损形貌、摩擦系数和磨损量的关系。结果表明,微动磨损机制是粘着磨损-疲劳脱层-磨粒磨损和腐蚀磨损;腐蚀介质下摩擦系数曲线比干空气的低且平稳;Al2O3\TC4摩擦系数曲线波动较大,载荷较大时由微动转为往复滑动。Si3N4\TC4磨损量和磨损率均比GCr15\TC4的大,GCr15\TC4耐磨性优于Si3N4\TC4,GCr15球作摩擦副材料时磨损性能最好。TC4在氯化钠溶液中的失重是由机械磨损、腐蚀和磨损的交互作用造成的。

英文摘要:
      Abstract: Fretting wear test of TC4 alloy in sodium chloride solution are studied, the effects of loads on wear scars, the friction coefficient and the wear resistance are investigated under different friction counterparts. Results show that the wear mechanism attributes adhesive wear to fatigue and peeling with abrasive wear, and corrosion wear appears on the surface; The friction coefficient decreases under the sodium chloride solution and the curves keeps stable; The friction coefficient curves of Al2O3\TC4 fluctuates greatly and the wear mechanism turns fretting into reciprocating sliding under the large loads. The wear rate and wear resistance of Si3N4\TC4 is larger than that of GCr15\TC4, which means the abrasion performance of GCr15\TC4is better than that of Si3N4\TC4 and GCr15 ball performed the best wear properties under the corrosive wear. The agravity of TC4 alloy is caused by wear and the interaction of wear and corrosion in sodium chloride solution.
