A process for the aluminum nitride - coating of the cylinder running surface of a crankcase of an al - base alloy and corresponding crankcase

摘要

A process for the aluminum nitride - coating of the cylinder running surface (zl) of a crankcase (kg) of an al - base alloy, wherein– the aluminum nitride - coating by means of nitriding of the al - base alloy, and– the activated nitrogen required for this purpose, by means of a high pressure - plasma process in the atmospheric area of molecular nitrogen is produced, and– the high-pressure plasma by means of static or pulsed corona - or barrier discharge or by injecting microwaves by means of an antenna (at) is generated.
