COSIM is a computer program that numerically simulates oxidation and diffusion in a metallic coating layer on substrates made of nickel-base alloys. COSIM is primarily useful for analyzing the gradual deterioration and predicting the lifetimes of the protective coating on turbine blades and vanes. At typical high operating temperatures, such deterioration involves oxidation and interdiffusion characterized by times of the order of tens to thousands of hours.
