Cylinder head for metal alloy for assembly of internal combustion engine, has cooling channel for coolant, where cooling channel has wear-resistant coating or channel wall has alloy constituents

摘要

The cylinder head (2) has a cooling channel (3a-3c) for coolant. The cooling channel has a wear-resistant coating or a channel wall has alloy constituents that increase the wear resistance relative to the metal alloy. The wear resistant coating is partially made up of chromium, titanium nitride or boron nitride.
