- the surface of the catalytic coating 7, T may be further treated after spraying until the surface has a desired roughness.
- a smooth surface is advantageous for the operation of the compressor, since little turbulence of the air flow is caused by these close to the surface, on the other hand, the catalytic effect is greater when the surface is increased, since in this case a larger area of the catalytic coating contributes to the catalytic effect.
- the surface can be smoothed by a suitable method such as grinding, drag grinding or glass beads. Then grooves or grooves can be selectively produced again in the surface, for example by sandblasting, so that depressions are formed by which the surface of the catalytic coating is enlarged in comparison to a smooth surface, but due to which hardly any turbulence arises since the air flow is only slight is influenced by such depressions.
