Abstract

A new bond coat system, “EQ coating,” designed to be in thermodynamic equilibrium with the Ni-based superalloy substrate has been proposed. Two types of EQ coating systems based on γ and γ′ compositions on the tie line of the base alloy (TMS-82+) were studied. Preliminary results have indicated that minimal interdiffusion occurred between EQ coating systems and the substrate. The EQ coating based on γ′ composition possesses the most promising oxidation resistance.
