发布时间：2019-06-19 12:20
【摘要】：采用销-盘式高速磨损试验机对TC11合金在0.5~4 m·s~(-1)下进行干滑动摩擦磨损实验,研究了TC11合金的磨损行为,并探讨了磨损机制。结果表明:在0.5~4 m·s~(-1)之间,4 m·s~(-1)时TC11合金磨损失重最低,其次为0.75 m·s~(-1)时的,而2.68 m·s~(-1)时磨损失重最大。不同速度下磨损量均随载荷的增加而增加,其中以2.68 m·s~(-1)时增加最为剧烈。TC11钛合金的磨损为黏着磨损、磨粒磨损和氧化磨损的综合作用结果。0.75和2.68 m·s~(-1)时以黏着磨损和磨粒磨损为主要磨损机制,4 m·s~(-1)时转变为氧化轻微磨损为主。不同工况下磨损过程中均形成摩擦层,4m·s~(-1)时不同载荷下摩擦层中出现数量较多的氧化物TiO、TiO_2,此时摩擦层硬度较高,具有显著地减磨作用。
[Abstract]:The dry sliding friction and wear test of TC11 alloy at 0.5 m 路s ~ (- 1) was carried out by pin-disk high speed wear tester. The wear behavior of TC11 alloy was studied and the wear mechanism was discussed. The results show that the grinding weight of TC11 alloy is the lowest at 4 m 路s ~ (- 1), followed by 0.75 m 路s ~ (- 1), and the highest at 2.68 m 路s ~ (- 1). The wear of TC11 titanium alloy increased with the increase of load at different speeds, especially at 2.68 m 路s ~ (- 1). The wear of TC11 titanium alloy was the comprehensive result of adhesive wear, abrasive wear and oxidation wear. 0.75 m 路s ~ (- 1) and 2.68 m 路s ~ (- 1) were the main wear mechanisms, and 4 m 路s ~ (- 1) was the main wear mechanism. The friction layer was formed in the wear process under different working conditions, and a large number of oxide TiO,TiO_2, appeared in the friction layer under different loads at 4 m 路s ~ (- 1). The hardness of the friction layer was higher and the wear reduction effect was significant.
