Influence of alloying additives in electrolyte and conditions of electrolysis on microhardness, adhesive strength and wear resistance of iron and cobalt coats have been investigated. Conditions of creating coats which make it possible to considerably enhance wear resistance of the mulcher teeth under the conditions of abrasive wear have been established. The process of creating wear resistant coats have been approved and recommended to introduction after the service life of the mulcher teeth sets have been extended.

Based on composite electrochemical coatings effect of content by volume of hard dispersed phase on coefficient of variation of microhardness has been considered. Besides model equation of relationship between content by volume of dispersed phase and coefficient of variation of microhardness has been worked out. The relation between the coefficient of variation of microhardness and volume content of a dispersed phase in a galvanic composite is established.
