Metal corrosion leads various problems such as degradation of structural materials. Since metal are used in various places ranging from large-scale structures such as nuclear power plants, chemical plants and bridges, to small facilities such as water pipes, many studies have been conducted to elucidate the basic mechanism of metal corrosion. In recent years, corrosion research using computational analysis has often conducted by high performance computing. In this presentation, we introduce our research on prediction of surface morphology by intergranular corrosion using macroscopic computational model, and surface adsorption reaction of chemical species in solution by quantum calculation.
