Abstract

The paper presents study results of Stellite-6/(WC+TiC) coatings produced by laser alloying with varying contents of reinforcing phases (40%wt and 60%wt content of mixture WC+TiC). The coatings were produced on S355 steel using different laser beam power densities: 76 kW/cm, 115 kW/cm and 153 kW/cm. The coatings obtained were subjected to microhardness measurements, wear resistance tests, chemical composition analysis and microstructure observations using light microscopy and scanning electron microscopy. It was found that both types of coatings were characterized by higher microhardness and wear resistance in comparison to substrate material. The rate of solidification had an impact on the obtained results of the study.

摘要

本文介绍了通过激光合金化制备的含不同增强相含量（WC + TiC混合物含量为40 wt%和60 wt%）的司太立合金6 /(WC + TiC)涂层的研究结果。这些涂层是在S355钢上使用不同的激光束功率密度制备的：76 kW/cm、115 kW/cm和153 kW/cm。对获得的涂层进行了显微硬度测量、耐磨性测试、化学成分分析以及使用光学显微镜和扫描电子显微镜进行微观结构观察。结果发现，与基体材料相比，两种类型的涂层均具有更高的显微硬度和耐磨性。凝固速率对研究获得的结果有影响。
