<p>A coated substrate comprises a base member (2) as well as a hard layer (4) on the substrate surface (3). The hard layer has the same expansion coefficient as the base member. The base member consists of a metal or metal alloy, especially steel, aluminum or copper. Anti-adhesive PTFE is applied to the hard layers. A coated substrate comprises a base member (2) as well as a hard layer (4) on the substrate surface (3). The hard layer has the same expansion coefficient as the base member. The base member consists of a metal or metal alloy, especially steel, aluminum or copper. A further hard layer (6) is applied to the surface of the first hard layer, and an anti-adhesive layer (8), especially PTFE, is applied to the hard layers.</p> |
