Abstract

The most effective method for improving wear resistance of rapidly wearing agricultural machine components reacting under operating conditions with an abrasive soil medium is application of hard alloy coatings by surfacing. The thickness of a surfacing layer is a factor governing the operating life of these components. Production limitations exist in applying hard alloy coatings connected with a reduction in their physicomechanical properties with an increase in surfacing layer thickness. In view of this, operating properties are studied for hard alloy coatings of different thickness for soil working components. Empirical dependences are determined governing permissible values of hard alloy surfacing layer thickness on components of working elements of solid treatment equipment. An effective production method is substantiated for applying hard alloy thick layer coatings. Production and materials science recommendations are given for preparing tool components.
