In this study, laser cladding process of WC on Inconel 718 is investigated. Response surface methodology (RSM) benefiting from the desirability approach is used to achieve cladded layer of proper geometry with minimum dilution, porosity, cracks, and highly efficient process. In order to validate the models, confirmation experiments are carried out and the results indicate that the laser power is the dominant factor affecting the dilution and clad width, while porosity and cracks are highly affected by scanning velocity. Furthermore, adhesion test results and subsequent hardness testing suggest good bonding of clad layer to the substrate as well as desirable quality of clad.

在这项研究中，研究了Inconel 718上WC的激光熔覆工艺。受益于可取性方法的响应面方法（RSM）用于以最小的稀释度，孔隙率，裂缝和高效的工艺实现具有适当几何形状的包覆层。为了验证模型，进行了确认实验，结果表明，激光功率是影响稀释度和熔覆宽度的主要因素，而孔隙率和裂纹受扫描速度的影响很大。此外，粘合测试结果和随后的硬度测试表明包覆层与基底的良好粘合以及期望的包覆质量。
