Abstract
By codepositing nickel and very fine particles of polycrystalline diamond, composite coatings that are controllable over a wide range can be produced on many base materials. Depending on particle size and packing density of the diamond, optimum properties can be attained for various applications. High concentration of diamond particles where extreme wear resistance is required, medium concentrations for specified coefficients of friction, coarse particles for intended abrasion of the respective counterpart in microfinishing. Currently the types of baths available are for parts of maximum 250 mm diameter and 450 mm length; weight of single pieces should not exceed 5 kg It is advantageous to coat small mass produced parts by barrel plating; partial coating is possible but often not economical. A standard coating should contain 20 to 30 % diamond by volume with a thickness of around 20 μmKeywords
