摘要

Process for coating a base material (1) with a protective layer (3) comprises exciting the base material during coating in an ultrasound frequency range using a transmitting head (6) connected to a vibrator (5). Preferred Features: The head is directly connected to the base material and the base material is directly excited. The protective layer is made of MCrAlY or a thermal barrier coating. The process is plasma spraying process or a physical or chemical vaporization process.
