High Temperature Friction and Wear and Oxidation Properties of Fe-Al/TiC Laser Cladding Layer
摘 要
采用高温摩擦磨损试验机研究从室温(25 ℃)至700 ℃下Fe-Al/TiC激光熔覆层与Si3N4球配副时的摩擦磨损特性, 探讨了涂层的高温摩擦磨损机理, 并在700 ℃进行了氧化试验。结果表明: 随着试验温度的升高, Fe-Al/TiC熔覆层磨损面形成了具有固体润滑作用的氧化物保护层, 使摩擦因数降低, 磨损率始终保持在较低水平, 700 ℃下磨损率是35CrMo钢的1/6; 熔覆层具有优良的抗高温氧化性能, 700 ℃下氧化150 h后质量增加为1.5 mg·cm-2, 比35CrMo钢的抗氧化性能提高40多倍; 熔覆层高温磨损的主要机理为剥层磨损。
Abstract
The friction and wear characters of Fe-Al/TiC laser cladding layers coupled with Si3N4 from room temperature (25 ℃) to 700 ℃ was investigated by high temperature friction and wear test. The mechanism of high temperature friction and wear was discussed and oxidation test was done at 700 ℃. The results show that the friction coefficient of the Fe-Al/TiC cladding layers decreased with the increasing of temperature for oxide protective layers with solid lubrication formed on cladding layers wear surface, and the wear rate always remained in lower level and was one sixth of that of 35CrMo steel at 700 ℃. The cladding layers had good high temperature oxidation resistant property, the wear quality added to 1.5 mg·cm-2 at 700 ℃ for 1.5 h and the oxidation property resistance increased more than 40 times compared with the 35CrMo steel. The main mechanism of cladding layers high temperature wear was delamination wear.
