METHOD OF APPLICATION OF COATS

FIELD: application of coats by gas dynamic methods. ^ SUBSTANCE: first flux is applied on surface of part at activity time of 0.2-0.25 h which contains up to 30% of ammonium chloride NH4Cl, up to 70% of zinc chloride ZnCl2 and up to 2% of potassium permanganate KMnO4. Then, surface is heated over fl...

Beschreibung
Zusammenfassung:	FIELD: application of coats by gas dynamic methods. ^ SUBSTANCE: first flux is applied on surface of part at activity time of 0.2-0.25 h which contains up to 30% of ammonium chloride NH4Cl, up to 70% of zinc chloride ZnCl2 and up to 2% of potassium permanganate KMnO4. Then, surface is heated over flux with the aid of torch producing oxidizing flame to temperature of (0.14-0.2)Tml., where Tml. is cast iron melting point. Then, part is treated with abrasive powder at size of particles of 30-300 mcm. Compressed air is heated and is fed to supersonic nozzle where supersonic air flow is formed; powder material for forming the coat is fed to this air flow in the direction of surface of article to be coated. ^ EFFECT: enhanced adhesion strength of coat on cast iron articles. ^ 2 dwg, 3 tbl, 1 ex
