摘要

以亚微米级TiC和CrxCy合金混合粉末为原料

采用激光合金化技术在球铁表面制备出耐磨、耐腐蚀、耐高温的合金化层。利用XRD、SEM、EDS等分析了激光合金化层的相组成及微观组织

并测试了激光合金化的显微硬度

在室温干摩擦条件下测试了涂层的耐磨性。结果表明

合金化涂层致密

硬度（HV）达930（测试载荷2000N）

干摩擦条件下材料磨损量是基材球墨铸铁的1/16

合金化涂层的耐磨性有一定的提高。

Abstract

Alloying coating with wear resistance

corrosion resistance

anti-high temperature was prepared on the surface of ductile iron using sub-micron TiC and CrxCy alloy mixed powder as raw materials by the laser alloying method.Constituent and microstructure of the alloying coating were analyzed by XRD

SEM

EDS

and micro-hardness was examined

and wear resistance was tested in condition of dry friction at room temperature.The results reveal that alloying coating with compact structure is 930 HV in micro-hardness and is 1/16 of ductile iron in wear rate in condition of dry sliding friction

showing the improvement of wear resistance of alloying coating.
