This ceramic coating is mainly used where a very high degree of chemical resistance against strong acids or bases is required. The coating is tribologically similar to the standard TOPCOAT®. The colour is dark grey/green.
The coating consists of a plasma-sprayed nickel-chrome adhesive layer with a minimum thickness of 100μm and a chromium oxide ceramic top layer of approximately 200µm.
The areas of application are the same as those of the standard TOPCOAT® ceramic coating, with the following differences:
- Further improved chemical resistance
- Improved hardness
- Improved wear resistance
- Relatively tough coating (by adding SiO2)
