FIELD: process engineering.
SUBSTANCE: invention relates to method of applying yttrium-containing coat on metal substrate including iron-containing substrates, e.g. cold-rolled steel and steel, subjected to electrolytic zincing in melt. Proposed invention aims at developing the method of applying yttrium-containing coat on substrate using composition intended for pretreatment and compound of IIIB- or IVB-group metals. For this, proposed method comprises bringing, at least, a part of metal substrate in contact with pretreatment compound. Said compound comprises IIIB- or IVB-group metal source and copper source. Then, at least, a part of metal substrate is brought in contact with pretreatment compound containing gum that forms film and yttrium source. Invention covers also coated substrates produced by described method.
EFFECT: higher coat quality.
