PROCESS OF DEPOSITION OF ALUMINUM COATS ON CAST IRON AND STEEL ARTICLES Russian patent published in 2003 - IPC

Abstract RU 2202649 C1

FIELD: deposition of coats by immersion in melt, anticorrosion protection of rolled products and cast iron and steel articles. SUBSTANCE: process includes jet-abrasive preparation of surface of article and its subsequent immersion in aluminum melt alloyed with zinc, silicon, magnesium and tin with following proportion of components. per cent by mass: zinc 7.0-10.0; silicon 3.0-5.0; magnesium 0.5-1.5; tin 0.2-0.5. Temperature of melt should be within limits from 660 to 680 C. EFFECT: decreased temperature of aluminum melt at which formation of sufficiently plastic coat without use of flux allowing rolled products and articles with aluminum coat to be deformed is provided. 2 tbl
