| 摘 要： | 为提高抽油杆表面的硬度和耐磨性,利用高频感应加热熔覆技术成功地在35CrMo钢基体上制备了TiN强化Co基复合涂层。涂层组织均匀致密,未出现明显的气孔、裂纹等缺陷。通过金相显微镜、扫描电镜、X射线衍射仪等手段研究熔覆层的组织结构,利用维氏显微硬度计表征涂层的显微硬度,并对涂层进行大削盘摩擦副试验,分别测试其摩擦系数和磨损量。结果表明:熔覆层的组织主要是γ-Co过饱和固溶体,且Cr_(23)C_6、Cr_2B以及TiN等硬质相弥散分布于Co基体上;熔覆层具有较高的硬度,TiN掺杂量为10%的涂层表面硬度达到了788HV_(0.1),且由结合面至涂层表面,硬度逐渐增加;在相同的磨损条件下,10%TiN/Co复合涂层的耐磨损性能最好,其摩擦系数和磨损量较未添加TiN的涂层分别降低了40%和45%;涂层的磨损机理为磨粒磨损和粘着磨损相结合。
