The paper is about the development of the coating from metal matrix composites with nanodiamond reinforcing particles to be applied for hard conditions including shock impacts. The main problem of using nanodiamonds in production of composites is their agglomeration, i.e., aggregation of primary nanodiamond particles 4–6 nm in size into agglomerates of up to 100 nm to 10 μm. Application of mechanical alloying for producing composites allows to obtain uniform distribution of separate initial nanodiamond particles inside copper matrix. Friction plating was applied for deposition of composite coatings. Deformation tests show that coatings applied by friction plating have high adhesion to substrate.
