Abstract

提出了一种激光熔敷专用粉末，其红硬性较高，耐磨损性相当突出，能适应功率范围相当宽的激光器熔敷。

Description

激光熔敷专用粉末
本发明涉及新材料领域；特别涉及激光熔敷专用粉末。
目前，激光熔敷粉末大多采用热喷涂用粉末。但是，激光熔敷的固有特性使热喷涂自熔合金粉末难以适应，特别是因目前我国所用的激光熔敷激光器的功率大部分都较低，以致沿用热喷涂粉末所得到的熔敷层出现极大的开裂倾向，严重地影响了激光熔敷这样的高新技术在我国的正常发展。
为解决上述问题，本发明在钴基粉末中添加硼、稀土(RE)、镍、钨、钼，对碳和铬含量进行了适当的调整，得到了如下成份(重量％)的新的合金粉末：C 0.5～0.7(例如0.6)，B 0.4～0.6(例如0.5)，Si 1.0～1.5(例如1.2)，Ni 10.0～12.0(例如11.0)，W 4.0～6.0(例如5.0)，Mo 3.0～5.0(例如4.0)，Cr 26.0～28.0(例如27.0)，RE＜1.0(例如0.5)，其余为Co。
本发明以上成份的合金粉末显示了高的红硬性，极突出的耐磨损性，适应功率范围宽的激光器熔敷。
