为获得钛合金单道单层激光熔覆的最优工艺参数,采用正交实验方法,进行激光熔覆成形试验。先找出激光功率、扫描速度和送粉速率对熔覆层几何尺寸的影响规律,再对比不同工艺条件所得熔覆层的表面及截面质量。 通过对比分析,得到一组用于单道单层激光熔覆的最佳工艺参数组合,为以后激光熔覆成形试验提供了数据参考。

In order to obtain the best process parameters of the titanium alloy single-track and single-layer laser cladding, the orthogonal experiment method was used, and have designed laser cladding forming test, found out the influencing rule of laser power, scanning speed and powder feed rate on the cladding layer geometric size. And contrast different process conditions of the cladding layer surface and cross section爷 s quality,through the contrast analysis, get a group of fine process parameters for single-track and single-layer cladding and provide data reference for later laser cladding forming test .
