Abstract
Machines, equipment and their partial segments used in agriculture, namely in the sphere of soil cultivating, are exposed to an intensive abrasive wear. Important producers of agricultural machines use sintered carbides, namely the tungsten carbide in the soil cultivating tools. The alternative to this solution is introducing the ceramic materials which have proved their positive wear resistance. This paper deals with the application possibility of the ceramic materials and adhesives in the tools used for cultivating the soil. Laboratory tests showed that a suitable choice of adhesive increased the system rigidity which means the energy absorption was increased during the impact on the ceramic surface. The ceramic Al2O3 was tested. The aim of the research is the evaluation of shear impact strength of adhesive bonds and the possibilities of using the ceramic materials as the wear resistant materials in the sphere of soil cultivation. Application of this solution demands coping with the adhesive bonding technology in obtaining firm and strong bonds which means the ceramics/steel interaction.
