| 摘 要： | 应用二次旋转组合试验进行试验设计，建立了喷砂距离、喷砂压力、喷砂角度与涂层和基体间结合强度的数学模型。通过降维分析法分析了双因素组合与结合强度之间的关系。结果表明：选用优化的预处理工艺进行粗化，可提高电弧喷涂涂层与基体铸铁的结合强度，满足一般使用要求。

| Abstract: | An investigation was carried out on iron cast with quadratic regression rotary combination test. The mathematical model which characterizes the relationship among parameters of grit-blasting, i.e., distance, pressure and angle, and adhesive strength was established. The influence of dual factor combination on adhesive strength was studied by dimension decreasing standard analysis. Results show that, there is an optimum value of adhesive strength on scope of test parameters; the pressure should be as high as possible; it is improper that the distance and angle are too higher or too lower; the technology of grit-blasting could greatly meet the demand of surface pretreatment for arc-spraying. |
