Sažetak

The paper describes preparation and properties of anti-corrosion and anti-abrasive coatings from corundum-baddeleyite ceramics deposited on surface of low-carbon boronized steel S235JRH-1.0038 (EN 10025-1) by plasma spraying method. Adhesive interlayers Fe₂B reaches bond strength of up to 20 MPa in the pull-off tests, the ZrO₂ - Al₂O₃ - SiO₂ coatings have a value of fracture adhesion of 4 - 6 MPa. Hardness of these ceramic coatings on steel is as high as 1 800 HV_{100 and its polarization resistance is 1 600 Ω/cm2 to 4 000 Ω/cm2.}
