Abstract: Currently, in order to increase the wear resistance of the working bodies of tillage machines, ceramic and metal-ceramic materials are the most promising. Ceramic materials have significantly greater wear resistance than hard alloys. However, their main drawback is increased fragility. This, in turn, significantly limits the use of ceramic materials for strengthening the arrow paws of tillage tools operated under conditions of significant impact loads. Metal-ceramic materials are a composite material consisting of a metal steel base (matrix) and ceramic components included in its composition (oxides, carbides, nitrides, etc.). The matrix provides these materials with the necessary impact strength, and the ceramic components provide high hardness and wear resistance. When strengthening working organs, metal-ceramic materials are most often applied from their cutting surface as coatings.
