Effect of parameters affecting solid particle erosion of crumb rubber epoxy composite is investigated. Five important process parameters-impact velocity, impingement angle, standoff distance, erodent size, and crumb rubber content-are taken into consideration. Erosion rate and erosion efficiency are included as the chief objectives. The Taguchi coupled gray relational analysis type statistical model is implemented to study interaction, parameters' effect on responses, and optimized parameters. ANOVA and regression model affirmed impingement angle and crumb rubber content play a significant role to minimize the erosion. Validity of the proposed model is justified with the standard probability plot and R value. A confirmation experiment conducted with ABCDE condition registers noticeable enhancement in GRG to the tune of 0.0893.
研究了影响橡胶颗粒环氧复合材料固体颗粒冲蚀的参数效应。考虑了五个重要的工艺参数——冲击速度、冲击角度、靶距、冲蚀颗粒尺寸和橡胶颗粒含量。将冲蚀率和冲蚀效率作为主要目标。采用田口耦合灰色关联分析类型的统计模型来研究相互作用、参数对响应的影响以及优化参数。方差分析和回归模型证实，冲击角度和橡胶颗粒含量对最小化冲蚀起着重要作用。所提出模型的有效性通过标准概率图和R值得到验证。在ABCDE条件下进行的验证实验表明，灰色关联度显著提高，达到了0.0893。
