Methods of restoration of hydraulic control valve spools by galvanic coatings are considered. Methods for preparing parts for applying electroplated composite coatings in order to increase the adhesion strength of electrolytic iron to alloy steel are proposed. The optimal modes of electrolysis for obtaining high-quality galvanic coatings are selected, the composition of the electrolyte is substantiated and the optimal content of the dispersed phase in it is selected. The design features of the coating bath for active mixing of the dispersed phase in the electrolyte are substantiated. The parameters of the technological process for spools restoration by applying composite galvanic iron-based coatings are proposed.
