In this study, pitting corrosion was investigated numerically and experimentally under actual operational conditions of a gas turbine compressor. First, the samples cut from a blade made a Custom 450 stainless steel were exposed to different corrosion times in a 3.5 wt% NaCl solution After the creation of pits in the samples, the dimensions of the corrosion pits were measured using a 3D profilometer device. The stoichiometry equations governing the corrosion of the Custom 45 alloy in a chloride solution were extracted and applied to the models. The results of this simu lation were validated by comparing the depth of the simulated pits and the experimental samples Subsequently, simulation was conducted for 48 months on a compressor having pits. There is a good agreement between the simulation results and the results obtained from the Turbo machine laboratory of the Texas A&M University. In addition, pits grew under the influence of corrosion joined together, and made an equivalent pit.
