| 摘 要： | 采用等离子弧表面淬火方法对45#钢和38CrMoA lA合金结构钢进行表面硬化处理,硬化深度分别为0.311和0.388 mm。在球-盘式摩擦磨损实验机上研究不同速度和载荷条件下,上述两种钢件的摩擦磨损特性。采用SEM观测磨损后涂层的表面形貌,探讨涂层的摩擦磨损机制。研究发现:38CrMoA lA硬化层表面硬度比45#钢高,且淬硬带无明显的硬度梯度;38CrMoA lA的磨损率低于45#钢,且随载荷和速度的增加而增加;不同载荷条件下,磨粒磨损、塑性流动和黏着磨损控制摩擦过程;38CrMoA lA的耐蚀性优于45#钢。

| Abstract: | The plasma arc surface quenching technique was applied to modify the surfaces of 45 steel and 38CrMoAlA steel,and the hardness penetrations were 0.311 and 0.388 mm,respectively.The wear resistances of the two above mentioned steels were investigated at variable loads with different velocities by a ball-plate tester.The wear removal mechanism and surface morphology after wear test were discussed by SEM.It is found that the increase in the load and velocity leads to the increase in wear rate.Different mechani... |
