Silicon-Based Technologies for High-Temperature Coatings and Their Corrosion Behaviours

Polymers based on silicon make excellent materials for coating applications in industrial sectors, manufacturing, energy sector, transportation, waste remediation, nuclear, space, etc. Coatings that withstand high temperatures offer compatibility with the environment as well as substrates play a crucial role. Strong adherence to the majority of surfaces, as well as good chemical, thermal and UV resistance, are only a few of these compounds’ outstanding qualities. In some situations, chemical processes or radiation can also be used to turn them into ceramic materials, in addition to heat treatment. Since they were first used in specialised, high-performance coatings, silicon-based technologies have become widely used in the coatings sector along with solar applications, functional qualities and high-temperature stability are also required for coatings. The current chapter examines several silicon-based technology high-temperature applications and corrosion mitigation where coatings play a crucial role and the parameters influencing their selection and processing step have been elaborated. Components that run at extremely high temperatures, such as gas turbines, jet engines and industrial plants, are subject to a phenomenon known as high-temperature corrosion. Every aspect of our existence is affected by corrosion, including buildings, bridges, utilities, as well as automobiles, trains and other moving vehicles. A crucial method of corrosion mitigation is coating. In most cases, corrosion happens when conductive ions, water and oxygen form an electrochemical cell on the metal surface. The formulator can lengthen the lifespan of the coated object and increase the longevity of a paint layer by limiting the penetration of these corrosion-causing substances. More formulators are able to meet stringent application requirements thanks to customised chemistries and efficient performance. This chapter examines the range of silicon-based technologies and the recent upsurge in silicon-based products. This chapter ends by discussing new surveys on coating qualities, providing advice to coatings formulators on how to employ silicon-based technology to improve their products and discussing the application of silicon-based coating to protect metallic alloys from high temperatures.
