摘要/Abstract

摘要： 利用电子束在Inconel 617高温合金表面熔覆WC-CoCr复合涂层,设计正交试验分析了工艺参数对熔覆层的影响,研究了优化后涂层的组织与性能。结果表明,电子束扫描束流对熔覆质量特性影响最为显著,优化工艺下获得的熔覆层与基体合金相互扩散并形成良好的冶金结合,熔覆层内出现了WC、CoCr、(Fe,Ni)C₆、Fe₃W₃C相以及α-Co的固溶体,电子束处理可有效抑制WC的分解,使涂层的显微硬度达1200 HV0.3。涂层的显微组织主要为CoCr基质上分布的枝晶和多种共晶,其在200、600和1000 ℃高温滑动磨损行为中具有比Inconel 617合金基体更低的磨损率和摩擦因数,耐磨性得到了提高。

Abstract: WC-CoCr composite coating was cladded on the surface of Inconel 617 superalloy by electron beam. Orthogonal experiment was designed to analyze the influence of process parameters on the clad layer, and the microstructure and properties of the optimized coating were studied. The results show that the beam current is the most significant influence on the quality characteristics of the coating. The clad layer obtained a good metallurgical bond, which undergoes ion exchange under the optimized process. The modified surface exists the WC, CoCr, (Fe, Ni) C₆, Fe₃W₃C phases and the α-Co solid solution, and the decomposition of WC is effectively inhibited by electron beam treatment, the microhardness reaches 1200 HV0.3. The microstructure of the coating is mainly the distribution of dendrites and a variety of eutectic on the CoCr matrix, which high temperature sliding wear behavior has lower wear rate and friction coefficient than Inconel 617 matrix at 200 ℃, 600 ℃ and 1000 ℃, wear resistance has been enhanced.

Key words: Inconel 617 alloy, electron beam cladding, high temperature wear resistance, process optimization
