Method for Introducing Non-metallic Particles into Composite Coatings

A method for producing composite coatings is proposed, in which initially a layer of non-metallic phase is created on the surface to be coated. For this, the product is wetted with a solution of copper sulfate, then a non-metallic phase is sprayed onto this layer. When the product is subsequently processed with phosphine, a primary metallic layer is formed, which fixes the non-metallic phase on the surface of the article. Further overgrowth by the metal phase (matrix) by galvanic or chemical means. The method allows to introduce up to 40% non-metallic phase.
