中文摘要:
      在对某重型车辆灰铸铁密封环进行失效分析的基础上,设计采用非平衡磁控溅射MoSi/CrAITiN双层膜工艺对其进行了表面耐磨减摩处理,并采用XRD、扫描电镜(SEM)等方法测试了其组织结构与基本性能。同时,在MM-200型环·块式摩擦磨损试验机上考察了该双层膜与其45钢偶件对摩时的摩擦学性能。结果表明:该双层膜组织主要为CrN、AIN、MoS7及少量的TiN,其显微硬度达1054. 3HVo.,;MoS,/CrAITiN双层膜与45钢对摩时摩擦因数比未经处理时明显降低,自身磨损重量及其偶件磨痕宽度均减少了约2/3。这说明在表层MoSi及次表层CrAITiN的协同作用下,复合处理后的灰铸铁的耐磨减摩性能明显提高,这是因为表层MoSi具有优良的润滑减摩性能,而次表层高硬度的CrAITiN具有较高的抗磨性能,并可以为接触面提供一定的支撑,抵杭塑性变形。
英文摘要:
      Failure mechanism of a sealed ring ( made of cast iron) of some heavy vehicle was analyzed first. Then on the basis of its failure mechanism, MoS2/CrAITiN bilayer films were prepared by unbalanced magnetron sputtering on the sealed ring substrate. The microhardness of the MoS2/CrAITiN bilayer films was 1054. 3HVo.s , about 3 times that of the cast iron substrate. XRD analysis showed that the main composition of the composite films system were CrN, AIN, MoS2 and a little TiN. Block-on-ring wear tests showed that the coefficient of friction was sharply reduced for the treated cast iron surface against 45 steel. Because of the superior lubrication property of the MoS2 above-layer and the wear resistance performance of the high hardness CrAITiN under-layer, the bilayer system shows favorable friction reduction as well as wear resistance.
