【摘要】 在一定的激光工艺参数下,对ZL108合金含SiO2和硅的涂层进行处理,其合金化组织细化,且出现过共晶组织。含钛+碳+铝涂层经激光处理后,存在TiC和Ti颗粒,提高了合金化层的硬度,明显改善了其摩擦磨损性能。更多还原

【Abstract】 With certain laser parameters, ZL108 alloy precoated with a coat consisting of Si and SiO2 was treated. The microstructure in the alloying zone was refined and the hypereutectic microstructure appeared. Moreover, ZL108 alloy with a coating containing Ti, C and Al was also treated, there existed TiC and Ti particles in the alloying zone, which increased the hardness and improved the wear and friction features of ZL108 alloy.更多还原
