摘要

In this paper,the new high temperature ceramic matrix coating of anti-oxidation for stainless steel was prepared by slurry method.With the research about oxidation resistance of ceramic matrix coating formed on stainless steel,the effect of initial melting temperature,melting temperature range and thermal expansion coefficients of ceramic sintering change on protective properties of high temperature coating prepared at 1250 °C is investigated,and then high temperature sintering ceramic with high-performance is gained through optimization.Through the test of TG-DTA and XRD to the coating,study on high temperature oxidation resistance of ceramic coating and the structure changing of the scale with coating from SEM images and photos,it is shown that the ceramic coating has excellent oxidation resistant properties,the weight loss with coating decrease more than 85%.
