FIELD: machine building.
SUBSTANCE: invention refers to machine building and can be used for production of chemical coating on parts out of materials operating under excessive wear, high pressure and at presence of aggressive mediums. With successive solving of components a solution is prepared; further surfaces are chemically or electric-chemically treated; then there is performed chemical application of coating from solution. This is followed with cold and hot water washing and drying. Nano diamonds with dimension of diamond aggregates in the range of 0.004-0.1 mcm at amount of 2-20 g/l are introduced into solution for chemical application of coating. In specific cases of the invention nano diamonds are introduced into solution in form of hydrosol or powder, or suspension.
EFFECT: upgraded physic-chemical properties of coating.
