Abstract: A process for producing a graphite cage for an anti-friction bearing, which cage holds a plurality of anti-friction elements. A cage injection molding is injected in an injection molding process from a mass which contains carbon mesophase powder, and this cage injection molding is subsequently heat-treated in order to transform the carbon from the mesophase into pure graphite.

Abstract: Production of a hardened, coated metal component, including the following steps: a. performing a heat treatment of the metal component for accumulating carbon and/or nitrogen in the edge layer of the metal component, b. quenching the metal component to a temperature below the martensite start temperature, c. annealing the metal component to a temperature that is higher than the temperature of a deposition method to be subsequently performed for applying a coating, and applying a coating via gas phase deposition.
