摘 要: 利用MJP-30A滚动磨损与接触疲劳试验机研究了两种水基摩擦改性剂(分别记为FM1和FM2)的最佳涂敷
量，分析了FM1和FM2在最佳涂敷量下对轮轨磨损和损伤的影响. 结果表明：FM1和FM2单次的最佳涂敷量分别为
14和8 μl. FM1介质下轮轨试样的磨损率明显降低，仅为干态下的23%和41%；FM2介质下车轮试样的磨损率略高于
干态下，钢轨试样的磨损率为干态下的64%. 干态和FM2介质下轮轨试样表面出现起皮、剥落及明显的疲劳裂纹，试
样剖面出现多层裂纹、支裂纹和次表层裂纹；FM1介质下轮轨试样损伤轻微，试样表面出现轻微起皮和点蚀，试样
剖面出现少量的单层微裂纹，FM1可有效减缓轮轨的磨损与损伤.

Abstract: Using the MJP-30A rolling wear and contact fatigue test rig, the optimum coating amounts of two kinds of
water-based friction modifiers (FM1 and FM2) were studied. The effects of FM1 and FM2 on wear and damage of
wheel and rail under the optimum coating amount were analyzed. The results showed that the optimum coating amounts
of FM1 and FM2 were 14 μl and 8 μl, respectively. The wear rates of wheel/rail specimens with the presence of FM1
medium were only 23% and 41% of those in dry condition. The wear rate of wheel specimen with the presence of FM2
medium was slightly higher than that in dry condition, and the wear rate of rail specimen was 64% of that in dry
condition. Under the dry condition or with the presence of FM2 medium, peeling, spalling and obvious fatigue cracks
appeared on the wheel and rail surfaces. On the cross sections of wheel and rail specimens, multi-layer cracks, branch
cracks and subsurface cracks appeared. With the presence of the FM1 medium, the wheel and rail specimens were
