A method of fabrication of the composite nickel coatings with concentration of nanodiamonds’ particles in the metallic matrix changed from one layer to another is developed by means of the programmable pulse current. As shown, the corresponding program of electrodeposition allows the layer-by-layer deposition of coatings with the lowest concentration of nanodiamonds in the external layers, and concentration of them is increasing in subsequent layers. That improves adhesive properties, increases wear resistance and reduces the amount of dispersed particles of nanodiamonds.
Key words: nanodiamonds’ particles, composite nickel coating, programmable pulse current, structure and mechanical properties.
