中文摘要：为了研究WC质量分数对Ni60粉末激光熔覆涂层性能的影响,采用激光熔覆技术在Q235碳素工具钢上制备了WC+Ni60的复合涂层,并进行了理论分析和实验验证,取得了熔覆层几何形貌、稀释率、显微组织及硬度方面的数据。结果表明,添加WC后,涂层外观成形良好,在涂层硬度上有明显的提升效果;稀释率随着WC质量分数的增加整体呈现先升高后降低的趋势;当WC质量分数为0.4时为合适的粉末配比,不但能保证微观组织致密、枝晶尺寸均匀,也可避免颗粒和气孔对涂层质量造成的影响,并保证了2种熔覆材料融合性和涂层整体硬度。此研究结果对激光熔覆添加WC的Ni基复合涂层制备有一定指导作用。

外文摘要：In order to investigate the effect of WC mass fraction on the properties of Ni60 powder laser cladding coating,the WC and Ni60 composite coating was prepared on Q235 carbon tool steel by laser cladding technology,and the theoretical analysis and experimental verification were carried out.The date of geometrical morphology,dilution rate,microstructure and hardness of cladding layer were obtained.The results show that,after adding WC,the coating has good appearance and the hardness of coating can be improved obviously.The dilution rate increased firstly and then decreased with the increase of WC mass fraction.When the WC mass fraction is 0.4,the appropriate powder ratio can not only ensure the dense microstructure and uniform dendrite size,but also avoid the influence of particles and pores on the coating quality,and ensure the fusion of two coating materials and the overall hardness of the coating.The results of this study have a certain guiding role for the preparation of Nibased composite with WC added by laser melting coating.
