The regularities of formation of the diffusion coatings structure on the surface of the Fe–Cr–Al alloy during hot-dip aluminizing with ultrasonic impact are studied. The phase and chemical compositions of the coatings have been established. It is shown that the ultrasonic impact leads to a change in the intermetallic phase ratio of the coatings without affecting their composition. Exposure to ultrasound promotes the formation of continuous coatings while minimizing the contact duration between the substrate and high-temperature melt.

Fe-Cr-Al合金超声冲击热浸渗铝表面扩散涂层结构的形成

研究了超声冲击热浸渗铝过程中Fe-Cr-Al合金表面扩散涂层结构的形成规律。涂层的物相和化学成分已经确定。结果表明，超声波冲击会导致涂层金属间相比例发生变化，但不会影响其成分。暴露于超声波促进了连续涂层的形成，同时最大限度地减少了基材与高温熔体之间的接触时间。
