We describe the technologies for production of composite metal-diamond coatings based on application of superdispersed diamonds (SDD) and electrochemical (galvanic) processes, which are widely used in the industry. We present the optimal parameters of the production processes and illustrate the main results obtained. We demonstrate that the composite coatings produced by application of the SDD electrochemical technologies have significantly better (in several times) performers as compared with those produced by application of the traditional electrochemical technologies.
