| Research Abstract |
Several Ni-low Al alloys with various metal coatings (-100nm) were oxidized at 1150℃ in air. Among the coating elements used in the present study, a thin Pt coating with the optimized heating treatment promoted the formation of Al_2O_3 scale on the Ni-14at%Al alloy. Al uphill outward diffusion was confirmed to occur after the heat treatment, and this Al outward diffusion was considered to cause the formation of Al_2O_3 scale on the Ni-low Al alloys.
