METHOD FOR PRODUCING METAL-POLYMERIC COATING Russian patent published in 2008 - IPC C23C24/04 C09D5/10 C09D177/00 C09D123/06 C09D167/02 

FIELD: metal processing.

SUBSTANCE: invention refers to processing of polymeric functional materials and can be used in machine building at coating of machine and aggregate units and units of transport systems, mainly pipes for transmission of oil products. The method for producing metal-polymeric coating consists in mixing polymer particles in a powdered form and metal containing precursor particles in a powdered form. Then a powdered mixture is settled on the surface of a unit and heated; polymer particles are melted. After that, thermolysis of the precursor and monolithic integration of coating are carried out. Polymer particles in a powdered form are selected out of a group containing polyamide, polyethylene terephthalate and polyethylene of high pressure. Particles in a powdered form of metal containing precursor represent formate or oxalate of copper, nickel, zinc or carbonyl iron. Heating, melting of polymer particles and thermolysis of precursor are carried out simultaneously in a thermo gas flow with a density of 3·10⁶ -9·10⁶ Wt/m² within 10^-4-10^-3 sec. The mixture is settled and monolithic integration of coating is performed on the unit heated to a temperature of T=T_m+5÷40°C, where T_m is the temperature of polymer melting at the density of the gas flow of 3-5 atm.

EFFECT: method allows for high processibility and upgrading of adhesion hardness, strength and rupture strength at tension.
