FIELD: process engineering. ^ SUBSTANCE: invention relates to foundry, particularly to fabrication of cylinder liner used in casting engine cylinder block. Film is formed on cast iron liner outer surface. Said film reduces adhesion between liner and cylinder block to form gaps there between. In compliance with another version, film heat conductivity is smaller than that of cylinders and/or liner. Cylinder liner is heated to produce film of oxide. In compliance with another version, said film is produced by electric-arc metallic coating. ^ EFFECT: preventing excess temperature reduction. ^ 27 cl, 27 dwg, 2 tbl |
