Coatings article na2so4 v2o5 corrosion behavior of band2ti3o10 for thermal barrier coating applications yajuan she yiwen guo zanxian tan and kai liao school of mechanical and electrical engineering hunan applied technology university changde 415000. For example aero engine and gas turbine parts that need to operate at elevated temperatures require tbcs. They are specifically designed to reduce heat loss from engine exhaust system components including exhaust manifolds turbocharger casings exhaust headers downpipes and tailpipes. Na 2 so 4 v 2 o 5 corrosion behavior of band 2 ti 3 o 10 for thermal barrier coating applications.

This process is also known as exhaust heat management when used under bonnet these have the positive effect of. 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. The quest for increased operating temperatures of gas turbine engines in order to achieve higher engine efficiency has driven the development of thermal barrier coatings tbcs for protections of superalloy components in the hot section of gas turbine engines a tbc system consists of a thermally insulating ceramic top coat an intermediate metallic bond coat and the.
