摘要: 利用二次回归正交组合设计法优化喷涂工艺参数,建立了等离子喷涂Al2O3p/NiCrBSi复合材料涂层冲蚀磨损失重率的二次回归方程.研究了等离子喷涂参数对涂层冲蚀磨损失重率的影响.结果表明,利用Matlab软件编程计算,优化等离子喷涂参数,明显提高了涂层的抗冲蚀磨损性能.为等离子喷涂制备以氧化铝(Al2O3)颗粒增强金属基(NiCrBSi)复合材料涂层(Al2O3p/NiCrBSi)的实际应用提供必要的理论依据和技术数据.Abstract: By means of the quadratic regression combination design process,the regression equations of erosion mass lost rate were established.Effects of plasma spraying paramaters on the erosion resistance of coatings were investigated.The optimum spraying parameters corresponding to the minimum erosion mass lost rate were obtained by using Matlab software.This work provides scientific basis and technology data for practical application of Al2O3p/NiCrBSi compsite coatings.
