    Research output: Contribution to journalJournal articleResearchpeer-review


    Interdiffusion at the interface between a Co-36.5Ni-17.5Cr-8Al-0.5Y, MCrAlY coating and the underlying IN738 superalloy was studied in a large matrix of specimens isothermally heat treated for up to 12,000 hours at temperatures 875oC, 925oC or 950oC. Modelled results using the finite difference software DICTRA were compared with experimental average composition profiles measured across the inteface using a new experimental approach.
