| Abstract: | The study was carried out in order to evaluate oxidation resistance of the ceramic coatings based on SiO2-B2O3-TiO2-Na2O 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. |
