The study was carried out in order to evaluate oxidation resistance of the ceramic coatings based on SiO 2 ‐B 2 O 3 ‐TiO 2 ‐Na 2 O composition deposited on the low‐alloyed steel T/P22 (10H2M) surface exposed for 1000 h at 540°C in oxidation atmosphere. Kinetic data were recorded periodically every 250 h; macro‐ and microanalyses as well as chemical composition were carried out using macrolenses, SEM, EDS, EDS X‐ray mappings. The results indicated a high degree of protection by ceramic coatings; much lower mass gain was observed for the coated materials than for the uncoated T/P22 (10H2M) steel. No detachment, delamination, chipping of a coating were found from the steel surface; some of the coatings showed perpendicular tiny cracks to the bulk metal surface.
