FIELD: production of cast products, possibly manufacture of casting molds, mainly for multiple casting of small-size articles with complex relief of surface.
SUBSTANCE: method comprises steps of preliminarily forming release layer corresponding to configuration of cast article and designed for applying coating. Release layer is applied directly on surface of article pattern and coating is applied in the form of mutually alternating N times (N=2 or more) plastic metallic layer and refractory layer of composition alloy with constant factor of temperature linear expansion. Sealing metallic layer is applied on surface of N-th refractory layer. After separating casting mold from pattern, inner surface of casting mold is oxidized.
EFFECT: enhanced operational reliability of casting mold, improved quality of cast articles, enlarged using range of method.
