摘要
金属材料的激光表面熔凝改性是一个正在兴起与拓宽的激光加工的应用领域 ,它是利用激光技术通过对金属表面熔池内的熔体流动来控制特定成分的表面材料的一种新工艺。本文重点讨论了激光作用下金属熔体的流动及其对凝固的影响。
Laser resolidification on metallic surfaces is one of new applied fields for laser processing,giving great attention to by material workers.The new technology is mainly to control chemical content of surface layer on metals,by adjusting the molten movement specialist in melt under laser irradiating.The aim of this paper is to discuss movement of molten metals and its effect on solidification under laser irradiating.
