APPLICATION METHOD OF THIN-FILM COATING ON METAL WORKS Russian patent published in 2009 - IPC C23C8/38 

FIELD: processes.

SUBSTANCE: invention can be used with manufacturing of cutting tools, products of triboengineering function, heavy loaded machinery and mechanisms. Coating is applied by means of displacement of low-temperature plasma stream, containing carbon, silicon, hydrogen, nitrogen, oxygen and argon, lengthwise the product surface. Products are preheated up to the temperature 50-100°C. Displacement of low-temperature plasma stream is implemented at a rate of 3-150 mm/s. Total time of coating is assigned depending on processing surface area and coating thickness.

EFFECT: ensured by coating of thin-film wear-resistant coating with defined thickness with high adhesion to the basis it is achieved useful increase of product's service durability by increased reproducibility.
