Abstract:
The effects by which minor element additives yttrium and hafnium and laser surface melting and rapid solidification laser-processing improve oxide scale adherence to NiCrAl were investigated. Laser-processed materials were isothermally and cyclically oxidized and oxide scale structure and adherence were examined. Laser-processing promoted thin, dense oxide formation in yttrium doped samples. Results are discussed in terms of effects for improved oxide scale adherence.
