Optimization of Laser Cladding Process Parameters via Taguchi Grey Relational Analysis and Evaluation of Associated Carbon Emissions
摘要
Abstract
A grey-based Taguchi orthogonal experimental design was employed to investigate the effects of laser power,scan-ning speed,and powder feed rate on the microhardness,dilution rate,and contact angle of cladding layers.Based on the ex-perimental data,grey relational analysis was utilized to optimize the multi-response process parameters,and the carbon emis-sions throughout the laser cladding process were modeled and analyzed using the method of life circle assessment.The results demonstrate that the powder feed rate exhibits an initial decrease followed by an increase in both microhardness and dilution rate,while the contact angle shows an initial increase followed by a decrease.Scanning speed displays an initial decrease fol-lowed by an increase in microhardness,a positive correlation with dilution rate,and an initial decrease followed by stabiliza-tion in contact angle.Laser power presents an initial decrease followed by an increase in microhardness and dilution rate,while maintaining a negative correlation with contact angle.The validation test results show only a 2.68%deviation from the predicted grey relational grade,highlighting the effectiveness and accuracy of grey relational analysis in optimizing laser clad-ding process parameters.Carbon emission analysis of the laser cladding coating optimized by grey relational analysis reveals a unit carbon emission of approximately 0.13 kg.The methodology proposed in this study can be applied to determine ideal processing parameters for multi-response laser cladding coating preparation and other industrial laser cladding applications.关键词
