The paper presents the research results of adhesive properties of plasma sprayed ceramic coatings on Al2O3 and ZrSiO4 base in tribological couples with 19 436 and 12 050 materials and polyamide. Ceramic layers are formed by three types of particles that differ, from each other inform and compactness. Non-compactness in the structure of the layer degrades its properties and it is possible to divide it into voids, pores, branched cracks and large particles. Among the investigated ceramic Al2O3 and ZrSiO4 based coatings the Al2O3 coating showed the best properties under adhesive wear conditions; this material, mainly in combination with 19436 material, is suitable for friction nodes. The wear value is in accordance with the course of the friction coefficient of the investigated tribological couples. The wear value is connected with the surface hardness of materials in the friction couple. The ceramics-polyamide couple appears to be high-prospective, since it shows a low friction coefficient and minimum wear and seizure tendency.
