Research progress in preparation and application of silicon-containing polymer derived high temperature resistant ceramic coatings
摘要
Abstract
With the continuous development of the aerospace field,the service conditions of high temperature structural components such as metal and carbon materials are increasingly harsh.The service life of high temperature structural components can be effectively improved by preparing silicon-based ceramic coatings on the surface of high temperature structural components and giving them special properties through appropriate processes.In recent years,the polymer precursors conversion ceramic coating has gradually become a novel method for preparing inorganic coatings.The new approach has the advantage of excellent processability and functional scalability,which gets more and more attention from researchers.The research progress of high temperature resistant ceramic coatings based on silicon-containing polymeric precursors was reviewed in this paper.Firstly,the preparation of ceramic coatings from the polymers was introduced,including the influences of silicon-based polymer precursors,fillers,coating and pyrolysis process on the structure and properties of the obtained coatings.Then,the applications of polymer-derived ceramic coatings in high temperature protection fields,such as anti-oxidation,environmental barrier and thermal barrier coatings were discussed.Finally,The problems in improving coating performance and defect control of polymer ceramic coatings were pointed out,and the development direction of polymer ceramic coatings was prospected,for example,by introducing ultra-high temperature elements such as Hf,Zr,Ta into silicon-based precursors,improving the temperature resistance level of ceramic coatings,and developing new efficient ceramic technology to improve the existing efficiency and applicability.关键词
