通过l9正交阵列实验，研究了激光熔覆工艺参数如激光功率、扫描速度、粉末进料速率等对aisi1040钢基体熔覆层质量特性（或熔覆层几何形状）的影响。为了在试验结果的基础上找到最优包层头的工艺参数设置，提出了一种基于灰色关联分析的多响应优化技术。将GRA应用于激光熔覆过程中，求出各实验的灰度关联度。通过优化，发现功率为1.25 kW，扫描速度为0.8 m/min，粉末进给量为11 gm/min是激光熔覆AISI 1040钢基体的最佳参数设置。此外，还进行了方差分析，以确定各控制因素对包层质量特性的贡献。最后，为了确保GRA的稳健性，在选定的最优参数设置下进行验证性检验。
The effect of various laser cladding process parameters like laser power, scan speed, and powder feed rate on clad bead quality characteristics (or clad bead geometry) for AISI 1040 steel substrate have been studied by performing a number of experiments withL9orthogonal array. In order to find the process parametric setting for best quality clad bead based on experimental results, a multiresponse optimization technique using gray relational analysis (GRA) is presented in this paper. The GRA is applied on laser cladding process to find out the gray relational grade for each experiment. On optimization, power of 1.25 kW, scan speed of 0.8 m/min, and a powder feed rate of 11 gm/min have been found to be the best parametric setting for laser cladding operation of AISI 1040 steel substrate. Moreover, the analysis of variance is also performed to determine the contribution of each control factor on the clad quality characteristics. Finally, to ensure the robustness of GRA, a confirmatory test is performed at selected optimal parametric setting.
