摘要(Abstract)：

采用高速电弧喷涂技术在Q235钢表面制备了FeMnCrNi/Cr_3C_2涂层。通过正交试验研究了喷涂电压、喷涂电流和喷涂距离对涂层形貌及性能的影响,获得了涂层制备的最佳工艺参数。利用扫描电镜、X射线衍射仪、能谱仪、显微硬度仪与激光共聚焦显微镜等研究了最佳工艺参数下制备的FeMnCrNi/Cr_3C_2涂层的形貌及性能。结果表明:影响涂层性能的主次因素顺序为:喷涂距离、喷涂电压、喷涂电流。最佳工艺参数为:喷涂电压31 V、喷涂电流240 A、喷涂距离200 mm。采用最佳工艺参数制备的涂层孔隙率为1.99%,显微硬度为719 HV0.1,是Q235钢的3.5倍,涂层的平均磨痕宽度、深度和截面积分别为281.95μm、4.42μm和564.81μm~2,相比Q235钢分别减小了60%、72%和89%,具有更优的耐磨性;涂层的主要磨损形式为磨粒磨损。
