Conditionally coatable materials
- Cast iron (lamellar graphite is better)
- Chromium- and nickel-plated metals
(only for light duty as adhesion between the galvanic plating and the base material is limited)
- Copper alloys (cleaning is complex)
- Aluminium alloys (low coating temperature required; limited stress resistance)
- Ceramics (must be electrically conductive or metallised)
Not coatable materials
- Sintered metal with open pores (not vacuum-compatible)
- Plastics (not high-temperature resistant and not electrically conductive)
