MODIFIED DIAMOND-LIKE CARBON (DLC) LAYER STRUCTURE

摘要

The invention relates to a wearing part which is comprised of a base material (51) and of a hard material layer (53), which is applied thereto and which contains carbon. Instead of being carbon steel, the base material is high alloy steel, particularly high alloy chrome steel. An inventive method for coating a base material of a wearing part with a hard material layer is characterized in that a mediator layer (52) is situated between the base material and the hard material layer and that the amorphous hard material layer containing carbon is applied by using a CVD method and/or a PVD method, in particular, inside the same reaction chamber used for subsequently applying the hard material layer.
