Process for producing a chemical-resistant protective layer for a rotary body having a base body made from fiber-reinforced plastic

摘要

A fiber-reinforced plastic base body is first of all provided with a coating of hard rubber or thermoplastic having a dispersed metal or ceramic content of 5% by volume to 80% by volume, and the coating is ground down to provide a smooth surface In a further step a layer of metal and/or ceramic, which has a printing function, is applied to the smooth surface, preferably by thermal spraying.
