研究了稀土铝镀层在超声场作用下的表面层厚度变化，通过对不同时间制备的稀土铝镀层的全浸蚀试验分析，提出了超声制备热浸稀土铝镀层耐蚀性的优化准则．
A new method has been developed for ultrasonic hot dip Re-A1 coating basing on flux method. During the hot dip process, ultrasonic vibration plays a role of microalloying and fragment in the coating, the anti-corrosion of the coating is improved remarkably. And this coating also does not influence the fracture strength of the substrate. The kinetics of the coating thickning in the ultrasonic hot dip process has been studied. An optimization criteri- on for anti-corrosion of ultrasonic hot dip Re-A1 coatings is suggested.
