A Comparative Analysis of Different Techniques of Thermal Barrier Coating

Numerous methods are used to put the ceramic material upon the substrate to form a film of the insulating material over it which is named as the thermal barrier coating to increase the life of the component and to reduce the pollution if applied in engine components. The coating is done to fulfill certain flaws of the substrate and to provide the surface that has the tendency to take the high temperature during operation. Also, thermal barrier coating is used to reach the higher efficiencies for a particular device like engine. The objective to enhance the efficiencies is to provide a substitute that can decrease the use of conventional resources like, fossil fuels. In this study, distinct techniques for the deposition of thermal barrier coating have been compared on the basis of their characteristics and forte. The methods are presented with their properties in this paper. It is not necessary that same method is used for the deposition of the top coat as well as the bond coat but there can be two different methods based on the requirement of the coating. The techniques used for the deposition not only affect the life of the thermal barrier coating but also the life of the component. So, the merits and demerits are compared for the different techniques in the present study.
