Abstract

The method proposes that after a coating of hard material containing silicon or wolfram has been applied to the cylinder surface the surface is honed. With a very fine honing tool a further honing operation takes place to expose the crystals of the harder material. A further honing then takes place to provide the surface with a microstructure finish
