Abstract

The paper presents research in the field of ceramic coatings. In the experiment, 5 types of ceramic coatings were applied to the base material by means of water-stabilized plasma, which was non-alloy quality structural steel S 235J2+N EN 10250-2-2000. The properties of surface treatment of the substrate by
blasting on Al2O3, Al2O3 with interlayer Ni, Al2O3+5% Ni, Al2O3+12 % Ni, Al2O3+20 % Ni were analysed. The quality of the surfaces was evaluated according to EN ISO 4287, where the values Ra and Rz were monitored. The quality of the ceramic coatings was analysed by light and electron microscopy.
