摘要
用多功能SRV试验机评价了热轧钢/热轧钢摩擦副在干摩擦条件下的高温减摩抗磨性能,并对高温磨损表面进行了分析。结果表明,在试验范围内热轧钢/热轧钢摩擦副的高温摩擦系数随时间的延长呈增长趋势,增长趋势的快慢与试验参数有关,高速时的高温摩擦系数明显低于低速时的高温摩擦系数;大量氧化铁磨屑的产生是造成热轧钢/热轧钢摩擦副高温摩擦系数上下波动的主要原因。试验速度对热轧钢/热轧钢摩擦副的高温磨损机理有很大的影响,在高速(0.32m/s)条件下,高温磨损机理主要是磨粒磨损;而在低速(0.10m/s)条件下,高温磨损机理主要是粘着磨损。
The wear resistance and friction-reducing properties ot hot rolling steel/steel pairs unuer dry friction and high temperature were analyzed by the SRV multifunctional test equipment. The results show that the high temperature friction coefficient of the steel/steel pairs appears the increasing trend with increasing test time, and the fast or slow of the increasing is a relation with the test parameters. The high temperature friction coefficient of steel/steel pairs at high speed is lower than that of at lower speed obviously. The fluctuation of the high temperature friction coefficient is owing to the emergence of a great deal of worn particles of iron oxide caused in the rubbing process. The test speed can clearly affect the high temperature wear mechanism of steel/steel pairs. At a high speed of 0. 32m/s ,the high temperature wear mechanism of steel/steel pairs is mainly grain wear, while at a lower speed of 0. 10m/s the mechanism is mainly adhesive wear.
