摘要
为了降低激光熔敷Fe-B涂层的高度脆性,使用不同成分的B4C和Fe-Ti合金混合粉末在奥氏体不锈钢基体上进行了激光熔敷,得到了具有TiB2晶须强化的复合Fe-Ti-B涂层、该涂层在保持原来Fe-B涂层的高硬度的同时,其抗裂性能亦得到了改善.
In order to reduce the high brittleness of laser clad Fe-B coatings, the Fe-Ti-B composite coating with TiB2 whiskers reinforcement was developed by laser cladding with a powder mixture of 640 and Fe-Ti alloy. Compared with Fe-B laser cladding coating, the cracking resistance of the Fe-Ti-B composite coating is obviously improved, while its hardness is not impaired.
