摘要

用高功率密度激光在铜基材料表面涂敷一层具有优异性能的镍基合金层。其间的结合强度是评价熔覆层质量的关键指标之一。试验结果表明

只要激光熔覆工艺合适

那么镍基合金激光熔覆层与铜基材料间就会形成冶金结合

此结合强度高于熔覆层的抗拉强度

其值大于90MN/m

Abstract

The Nibase alloy layer with excellent performence is clad on the surface of copper alloy by using high-power laser.Their binding strength is one of important standardes for evaluating qulity of cladding layer.Experiment shows that provided laser cladding craft is right

the metalurgical bind is formed between laser cldding Ni-base alloy and substrate of copper alloy.The binding strength is lager more than Ni-base alloy layer strength for extension and over 90 MN/m
