Abstract

In a process for coating the blades of a rotating, thermal machine, said blades undergo a first cleaning process in the operating state of the machine, i.e. "on line", the appropriate agent fox this, which depends on whether the blades are uncoated or coated, being mixed in with the air stream to the compressor.
After switching off the machine and opening the same, the blades undergo in the stationary state, that is to say in the bladed state of the corresponding rotor or stator, a preparation process for the subsequent treatment stage. According to requirements, this preparation process may, for example, consist in the blades being immersed in a vibrating erosive bath. The actual coating of the blades takes place by means of a high-speed flame spraying process, in which the protective coating is sprayed onto the surface of the base material at a particle velocity of at least 300 m/s. Thereafter, the blades also undergo an after-treatment which, according to requirements, serves to reduce the surface roughness and/or is provided to apply a top coating.
