摘要
设计了制备FeCrMoCBSi系非晶合金涂层用的粉芯线材L1和添加镍稀土的对比配方L2,用电弧喷涂技术制备了两种非晶合金涂层。采用X射线衍射仪(XRD)、扫描电镜(SEM)、差示扫描量热仪(DSC)、显微硬度仪测试了涂层的组织结构与性能,采用冲蚀磨损测试设备测试了两种涂层在30°和90°冲蚀角下的耐冲蚀磨损性能,并用SEM观察了涂层冲蚀后的表面形貌。结果表明,添加镍稀土的L2涂层与L1相比,非晶相含量升高了5.7%,组织结构更加致密,截面平均显微硬度提高了149.6HV0.1,晶化转变温度Tx增加了7K,涂层在相同测试条件下的耐冲蚀性能也有所提高。
The cored wire L1 which is used to manufacture FeCrMoCBSi amorphous coating and the compared cored wire L2 which append Nickel rare earth alloy were developed and the two kinds of amorphous coatings were prepared by arc spraying technology.XRD,SEM,DSC and micro-hardness tester were used to examination the property and structure of the coatings.The erosion wear resistance of the two coatings at 30 ° and 90 ° erosion angle were tested by the erosion wear test equipment,and the surface morphology of the coatings after erosion were observed by SEM.The results showed that the L2 coating has better property than L1,the coating＇s amorphous phase content increase by 5.7 %,the structure is more dense and uniform,and the average hardness of the coating increase by 149.6 HV0.1,the transition temperature of crystallization increase by 7 K,and the erosion wear resistance of the coating is also improved under the same conditions.
