Thermal barrier coating applications.

Thermal barrier coatings thermal barrier coatings or tbcs play a critical role in the insulation process of a wide spectrum of components in various industries. They are specifically designed to reduce heat loss from engine exhaust system components including exhaust manifolds turbocharger casings exhaust headers downpipes and tailpipes. Thermal barrier coatings tbcs have been in use in aeroturbine engine hot sections for over 20 years. Sps can produce porous coatings comparable with the aps coatings and columnar coatings similar to the electron beam physical vapor deposition eb pvd.

Thermal barrier ceramic coatings are becoming more common in automotive applications. Hundreds of different types of coatings are used to protect a variety of structural engineering materials from corrosion wear and erosion and to provide lubrication and thermal insulation. This process is also known as exhaust heat management when used under bonnet these have the positive effect of. Saint gobain zirpro offers a comprehensive range of zirconium oxide powders to meet the needs of the coating process.

In addition to their chemical properties these ceramic thermal barrier coatings are capable of forming the microstructure and porosity necessary to achieve optimum performance. Authors nitin p padture. The initial applications were driven by the need to suppress component degradation caused by. For example aero engine and gas turbine parts that need to operate at elevated temperatures require tbcs.

Na 2 so 4 v 2 o 5 corrosion behavior of band 2 ti 3 o 10 for thermal barrier coating applications. By yajuan she yiwen guo zanxian tan and kai liao school of mechanical and electrical engineering hunan applied technology university changde 415000 china author to whom correspondence should be addressed. Of all these thermal barrier coatings tbcs have the most complex structure and must operate in the most demanding high temperature environment of aircraft and industrial gas turbine engines.
