Abstract
New and improved nickel-, cobalt- and iron-base bond coatings have been identified for the ZrO 2Y 2O 3 thermal barrier coatings to be used on nickel-, cobalt- and iron-base alloy substrates. These bond coatings were evaluated in a cyclic furnace between 1120 and 1175°C. It was found that MCrAlYb (where M Ni, Co or Fe) bond coating thermal barrier systems have significantly longer lives than MCrAlY bond coating thermal barrier systems. The longest life was obtained with the FeCrAlYb thermal barrier system followed by the NiCrAlYb and CoCrAlYb thermal barrier systems in that order.
