摘要
对宽带激光熔覆不同熔覆材料的复合涂层的耐磨性能进行研究。结果表明N i60B熔覆层的硬度高于40Cr基材的硬度,N i60B+WC梯度复合涂层具有最高的硬度,对于提高零件的抗磨损性能比较有利;N i60B熔覆层和N i60B+WC熔覆层均适合修复轴类零件;三层梯度复合涂层磨痕宽度最小,具有最好的耐磨性。
According to research on complex coating abradability of different fusion material in laser band laser fusion, results show： the solidity of Ni60B coating is higher than that of 40Cr base material, Ni60B ＋ WC gradient complex coating has the highest solidity helpful to enhance the abradability of accessories; Ni60B coating and Ni60B ＋ WC coating are suitable to fix axial parts; three - layer gradient complex coating has the least abradability breadth, and has the best abradability.
