Abstract
A system for bonding layers () of different chemical compositions, such as bonding a thermal barrier layer to a metal substrate on a surface of a gas turbine component. A substrate () made either of a ceramic material or particularly of a metal super-alloy may be bonded to an outer layer () such as a ceramic by means of a fine-grained intermediate layer () bonded to the substrate (), and a coarse-grained layer () bonded to the intermediate layer () to create a studded surface (). The fine and coarse layers () provide a transition between the substrate () and the outer layer () for improved bonding between them. The studded surface () may provide at least a 20% increase in bonding surface area for the outer layer (). Additionally, a medium-grained layer () may be applied to the studded surface () before applying the outer layer().
