摘　　要：在其他条件一定的情况下 ,采用二次旋转正交组合试验设计方法 ,以活化电流密度、活化时间为因素开展试验 ,探索球墨铸铁、45钢及 40 Cr最佳活化规范。通过研究分析了活化电流密度及活化时间对结合强度的影响规律 ,指出 3种材质最佳活化规范差异 ,并在金相。The article discussed the best activation standard of ductile iron, 45# carbon steel and 40 chromium alloy, adopting the quadratics rotary orthogonal combination experiment design method, taking activation current density and time as two factors when the other circumstance was stable. By analyzing the rule that the activation current density and time influence the adhesion strength, the differences of the best activation standard among the three materials were pointed out. The mechanism of activation was analyzed based on the metalgrophic test and scaning electronmicrograph.
