Abstract

In this work, a study was carried out by modifying the conventional Tungsten Carbide Cobalt Chrome (WC–10Co4Cr) powder with a small addition of yttrium-oxide (Y₂O₃). Reinforcement was done by adding yttria (Y₂O₃) ceramics in WC–10Co4Cr powder by using a jar ball mill process. The surface microstructure, chemical composition, and phase compositions of coating powder and coatings were examined by using scanning electron microscopy, energy dispersive spectroscopy, and X-ray diffractometry. Silt erosion was evaluated through a pot tester by preparing equi- and multi-sized slurries at different velocities, impact angles, concentrations, and rates. Results show that the WC–10Co4Cr powder coating reinforced by Y₂O₃ ceramics possesses low porosity, providing higher erosive performance as compared to conventional WC–10Co4Cr coating. The present study reveals that the deposition of conventional WC–10Co4Cr coating helps improve the wear resistance of AISI 316L stainless steel (UNS S31600) by 9.98% for the variation in rotational speed. However, the erosive wear performance of conventional WC–10Co4Cr coating was improved by 45.9% by blending it with the Y₂O₃ ceramics.

基于神经网络的Y2O3/WC-10Co4Cr HVOF涂层冲蚀磨损性能分析研究

本研究通过添加少量氧化钇（Y2O3）对常规碳化钨钴铬（WC-10Co4Cr）粉末进行改性。采用罐式球磨机在WC-10Co4Cr粉末中加入钇（Y2O3）陶瓷进行补强。采用扫描电子显微镜、能谱仪和x射线衍射仪对涂层粉末和涂层的表面微观结构、化学成分和相组成进行了研究。通过一个罐子测试来评估泥沙侵蚀，在不同的速度、冲击角度、浓度和速率下制备等尺寸和多尺寸的泥浆。结果表明：Y2O3陶瓷增强WC-10Co4Cr粉末涂层孔隙率低，耐蚀性能优于常规WC-10Co4Cr涂层；本研究表明，常规WC-10Co4Cr涂层的沉积使AISI 316L不锈钢（UNS S31600）在转速变化下的耐磨性提高了9.98%。与Y2O3陶瓷共混后，WC-10Co4Cr涂层的冲蚀磨损性能提高了45.9%。
