摘要

采用微波混合加热技术，在 AISI-316 不锈钢上形成了镍-13%WC8Co 的保护性复合包层。采用 XRD、SEM、EDS 和维氏硬度测试仪进行了冶金和机械表征。在冲击角为 30°、45°、60° 和 90°、速度为 40 米/秒的条件下对侵蚀磨损进行了评估。将包覆材料与钢稀释后，两者之间形成了良好的冶金结合。扫描电子显微镜图像显示了软镍基体中的硬质合成碳化物。衍射图样显示形成了 WC、NiW、FeNi3、Co2C 和 Co3W3C2 相。Ni-13%WC8Co 复合材料的显微硬度值为 1000.8 HV，侵蚀率比 AISI-316 不锈钢低四倍。在被侵蚀的堆焊表面上可以观察到凹坑、划痕和犁痕。Ni-WC-Co 复合材料的侵蚀磨损机制为韧性-脆性混合，侵蚀率总体较低。

Characterization and erosion wear behavior of Ni-13%WC8Co microwave clad on AISI-316 steel

A microwave hybrid heating technique was used to develop a protective composite cladding of Ni-13%WC8Co over AISI-316 stainless steel. The metallurgical and mechanical characterizations were done using XRD, SEM, EDS, and Vickers microhardness testers. The erosion wear was assessed at impact angles of 30°, 45°, 60°, and 90° and a velocity of 40 m/s. The dilution of clad material with steel resulted in good metallurgical bonding between the two. The SEM images have shown the hard cemented carbides within the soft nickel matrix. The diffraction pattern indicated the formation of WC, NiW, FeNi3, Co2C, and Co3W3C2 phases. Ni-13%WC8Co clad has a microhardness value of 1000.8 HV and a four times lower erosion rate than AISI-316 stainless steel. The craters, scratches and plowing marks are observed on the eroded clad surface. The erosion wear mechanism of Ni-WC-Co clad was mixed ductile-brittle, with an overall lower erosion rate.
