Japan has the special feature that there are a lot of natural disasters compared with other country. Recently, the volcanic explosion at Mt. Fuji has been paid attention. If Mt. Fuji is exploded, it is expected that land-based gas turbines utilized as power generator in Tokyo bay inhales aerosol-like volcanic ash and its ash deposits on the turbine blade, and also all generators are stopped. In this study, high temperature corrosion property of nickel-based superalloy IN738LC deposited by volcanic ash was examined. In order to achieve this purpose, high temperature exposure test and microstructure observation by SEM were conducted. Vickers hardness test and tensile test were also performed.
