中文摘要：为提升TC4钛合金零件的使用寿命和性能,利用正交试验方法设计多组激光工艺参数,采用激光熔覆工艺分别在钛合金表面上制备了镁钴合金涂层,分析了激光脉冲电流、脉冲宽度和扫描速度对熔覆层稀释率和宽高比的影响以及每个试验影响因素之间的交互作用,并进行验证试验,最终获得钛合金表面单道激光熔覆的最优工艺参数。结果表明,扫描速度对熔覆层稀释率的影响最大,脉宽对宽高比影响的最大。通过对比分析得出最佳工艺参数组合,为今后的钛合金激光熔覆镁钴合金的成形试验提供试验借鉴。

外文摘要：In order to improve the service life and performance of TC4 titanium alloy parts,design of multiple laser process parameters using orthogonal test method.Mg-Co alloy coatings were prepared on titanium alloy the surface by laser cladding process.The influences of current,pulse length and scanning speed on the dilution rate and aspect ratio of cladding layers as well as the interactive action among the each influencing factors are analyzed and verification experiments.Finally obtain the best process parameters of the titanium alloy single-track laser cladding.The results show that the scanning speed has the most significant influence on the dilution rate of cladding layer,while the pulse width has the most obvious influence on the aspect ratio of cladding layer.Through the contrast analysis,the best combination of process parameters was obtained,and provide experimental reference for later laser cladding of titanium alloy magnesium-cobalt alloy forming test.
