ABSTRACT:
The invention concerns a method for blacking components. In order to develop a method which creates black surfaces on components which are not inclined to peal off, and in which no fluids or baths are used which are expensive to produce, maintain or dispose of, it is proposed that the surfaces of the component are subjected to a heat treatment with simultaneous administration of a carbon-emitting medium inside the processing space. Furthermore, the invention concerns a device that can be operated using the method of the invention.
