FIELD: metallurgy. SUBSTANCE: the offered body of mold is made of aluminum alloy with protective lining in form of alternating layers of titanium and titanium nitride applied to its working surface. In process of contact of melt with surface of mold lining, casting is formed. Prior to application of lining, the mold working surface is polished to obtain lining surface roughness not in excess of 0.63 mcm. EFFECT: higher stability of mold and produced castings. 1 dwg, 1 tbl
