This book deals with the investigation of plasma sprayed Yttria partially stabilized zirconia (Y-PSZ) as thermal barrier coating (TBC). The thermal barrier coating, as the name suggests, is a coating of material of low thermal conductivity value, low enough to make it capable to reduce heat from the hot working fluid to penetrate into the substrate in high temperature applications like diesel engines, gas turbines etc. The investigation has been made in terms of thermal behaviour and thermo-physical behaviour of plasma sprayed Y-PSZ coating over aluminium (12 % by wt. Si) substrate using...
