摘要

Inconel617 合金材料在实际应用中以耐腐蚀性、高温抗氧化性能和耐磨性为主。但是，其本身耐磨性比较低。为了提高Inconel617 合金表面耐磨性，采用高速火焰喷涂与电子束表面改性技术在Inconel617 合金表面制备了WC–CoCr 陶瓷涂层。分析了合金层的微观组织结构和元素分布情况，测试了合金层的硬度与耐磨性。结果表明，在电子束熔覆处理过程中，涂层重熔与基体形成冶金结合，使其耐磨性能大大提高。熔覆层硬度相比Inconel617 合金硬度高出620HV0.3。

Abstract

The material of Inconel617 alloy has the properties of corrosion resistance

high temperature oxidation resistance and wear resistance in the practical application. But

its wear resistance is poor. In order to improve the wear resistance of Inconel617 alloy

HVOF (high velocity oxygen fuel) and electron beam surface modification technology were used to prepare WC-CoCr ceramic coating on Inconel617 alloy. The microstructure and element distribution of the alloy layer were analyzed. Hardness and wear resistance of the alloy layer were tested. The results show that in the process of electron beam processing

the forming metallurgical bond of coating remelting and matrix could increase wear resistance significantly. Compared with the substrate

hardness of the cladding layer improves significantly.
