    On the basis of theoretical and experimental studies with the application of the similarity and dimensional theory and planning of multifactorial experiments typical similarity criteria, criterion equations and regression mathematical models of reduction processes are obtained, verification of their adequacy and optimization by means of a steep ascent method is conducted.
    The physico-mechanical properties (adhesion strength, hardness, wear resistance) of the obtained metal coatings are investigated and resource-saving technological processes are developed for recovery of worn-out parts of agricultural machinery via iron-plating, electroplating and electric-spark alloying in order to increase their reliability.

    As a result of researches the original compositions of electrolytes, accessories and recovery modes are worked out, the novelty of which is justified by appropriate patents and author’s certificate for invention.
