摘要
采用激光熔覆技术,在Q235碳素钢表面制备不同质量分数的Fe60+WC复合涂层,通过金相显微镜、显微硬度计、扫描电子显微镜(SEM)、能谱分析仪(EDS)、X射线衍射仪(XRD)等研究了熔覆层的宏观形貌、微观组织、硬度分布、物相组成等。结果表明,加入WC,可以生成硬质相,从而使得加入后的Fe60熔覆涂层能够有效地提高Q235碳素钢的硬度;当WC质量分数为3%时,硬度能达到基材的8倍,且为最大值。
Fe60+WC composite coating with different quality fraction was prepared on the surface of Q235 carbon steel,and the macromorphology of microscopy,microhardness tester,scanning electron microscopy(SEM),energy spectroscopy analyzer(EDS),and X-ray diffractometer(XRD)were studied.The results show that WC addition can form a hard phase,so that the added Fe60 coated coating can effectively improve the hardness of Q235 carbon steel.When the WC mass fraction is 3%,the hardness is 8 times of the substrate,which reaches the maximum.
