A full three-factor two-level factorial experimental design method was carried out to investigate the effects of a single factor and their combining actions on weight loss of 304 stainless steels (304 SS). Quantitative analysis was performed to calculate the contribution values of temperature, rotation speed, sulfuric acid concentration, and synergistic actions. In particular, an 8 × 8 matrix was designed for the first time to define variation direction of erosion wear rate by qualitative analysis. The results show that slurry temperature has the most significant influence followed by sulfuric acid concentration. Rotation speed has the smallest effect. The synergies of the parameters all accelerate the weight loss rate, but they exhibit different intensity. This research provides useful guidelines for estimating the effects of environmental factors and material design in practical engineering application.
采用全三因素两水平析因实验设计方法，研究单因素及其组合作用对304不锈钢（304 SS）失重的影响。进行定量分析以计算温度、转速、硫酸浓度及协同作用的贡献值。特别地，首次设计了一个8×8矩阵，通过定性分析确定冲蚀磨损率的变化方向。结果表明，浆料温度的影响最为显著，其次是硫酸浓度。转速的影响最小。各参数的协同作用均加速了失重率，但强度不同。该研究为实际工程应用中评估环境因素的影响和材料设计提供了有益的指导。
