摘要: 应用IPG-500激光器对45号钢进行了激光熔覆,研究了工艺参数对熔覆层形貌的影响,采用极差分析找出影响熔覆层形貌的关键因素.在此基础上,提出采用灰色关联度分析不同参数组合下的熔覆层质量与理想的熔覆层质量之间的关联度,从而找出最佳的激光熔覆工艺参数组合.结果表明,激光功率与扫描速度是影响熔覆层形貌的主要因素,并且在激光功率为400W,扫描速度为7mm/s及送粉速率为0.7r/min的条件下,所获得的熔覆层质量最优,为激光熔覆工艺参数的选择提供理论支持.

Abstract: The IPG-500 laser was used to implement laser cladding on 45# steel. The influence of process parameters on the morphology of the cladding layer was studied, and the key factors affecting the morphology of the cladding layer were obtained by range analysis. On this basis, the gray correlation degree was used to analyze the correlation between the quality of the cladding layer and the ideal cladding layer quality under different parameter combinations, and the optimal combination of laser cladding process parameters can be found. The results show that the laser power and scanning speed are the main factors affecting the morphology of the cladding layer, and the optimized cladding layer is obtained under the conditions of laser power of 400W, scanning speed of 7mm/s and powder feeding rate of 0.7r/min, which provides theoretical support for the selection of laser cladding process parameters.

Key words: remanufacturing, laser cladding, range analysis, parameter optimization, grey relational degree
