ABSTRACT:
A process for galvanic deposition of chromium coatings is provided in which the base material is subjected to a galvanic chromium plating bath to form a hard chromium coating with beaded or columnar type surface structure, and the beaded or columnar type surface structure is subsequently filled and smoothed with galvanically applied black chromium. The resulting combined coatings yield increased wear resistance, lower friction values, even without lubricants, and increased corrosion resistance.
