基于响应面分析法的激光熔覆仿真实验教学设计与研究
Design and Research on Virtual Simulation Experimental Teaching of Laser Cladding Based on Response Surface Analysis Methodology
摘要
Abstract
To address issues such as cracks,porosity,and deformation that are prone to occur in cladding layers,this article uses G-X5CrNi134 martensitic stainless steel as the substrate and Stellite 6 cobalt-based alloy as the laser cladding powder.A regression model was established based on previous experimental data using software such as Design-Expert 13.Response surface analysis was employed to analyze the resulting mathematical model,and the optimal laser cladding process parameters were determined as follows:laser power of 2 000 W,powder feeding rate of 7.34 g/min,and scanning speed of 350 mm/min.Laser cladding experiments confirmed that the Stellite 6 cobalt-based coating prepared under the optimal parameters is tightly bonded to the substrate,is free of defects such as porosity and cracks,and has a moderate aspect ratio.This experiment proposes an optimized strategy for laser cladding of cobalt-based coatings,integrating parameter optimization modeling and virtual simulation.It combines the application of diverse data analysis tools with an in-depth understanding of experimental processes,and offers strong cross-platform scalability and adaptability for engineering education.This approach is well-suited for research-oriented materials design experiments in undergraduate teaching,effectively fostering students'innovative thinking and comprehensive practical skills.关键词
