Abstract
Platinum aluminide diffusion coatings act as a remedy against the aggressive environments in which modem aero-gas turbines operate. The increase in operating temperatures of industrial energy systems and gas turbines, often coupled with the decrease in fuel quality being employed, has led to the extensive use of coatings capable of providing improved service life. Interdiffusion plays a critical role in understanding the integrity of such coatings. This paper presents a review of the interdiffusion issues in Pt-modified nickel aluminide coatings. The mathematical model for interdiffusion in multi-component open systems which allows for the description of a wide range of processes (e.g., processes stimulated by reactions at interfaces) is employed for the modeling of interdiffusion in the Pt-modified beta-NiAl on MAR M002 superalloy and in the Pt/ beta-NiAl coatings systems. The Inverse Method which permits calculation of the intrinsic diffusivities, for an arbitrary number of components in a system, is presented.
