Abstract
A bond coat and method of forming a bond coat for a thermal barrier coating system are set forth. The bond coat is a roughened bond coat and comprises a layer possessing an uneven, undulated, and irregular surface. The layer is formed of a metal powder mixture disposed on a substrate, such as a turbine component, by high velocity oxygen fuel spraying. The metal powder mixture comprises at least one of a first powder having a first melting point and a second powder having a second melting point that is higher than the first melting point. The bond coat's uneven, undulated, and irregular surface enhances prevention of de-bonding of elements in a thermal barrier coating system.
