  • Coated cutting member having a nitride hardened substrate
    Publication number: 20060201001
    Abstract: The invention relates to a cutting member (7) for use in a device for shaving hair. The cutting member comprises a steel substrate (15) which is provided with a cutting edge (9). At least a portion of a surface (27) of the substrate including the cutting edge is provided with a protective coating (19) having a hardness which is higher than a˜hardness of the steel substrate. According to the invention, the portion of the surface (27) of the substrate (15) provided with the coating (19) is nitride hardened. As a result, the substrate provides an improved mechanical supporting function for the coating. In this manner, the risk that the coating will break as a result of deformations of the substrate, which occur under', the influence of high mechanical loads on the coating and on the cutting edge (9), is considerably limited.
