applications in the aerospace and power industries due to the formation of thermodynamically stable Al2O3 scale at high temperatures [1,2]. Recently, Ni-Al alloy coatings with good isothermal oxidation... authors [16,17] found that the codeposited Y2O3 or CeO2 particles significantly improved the isothermal oxidation resistance of Ni-Al alloy coatings. LIU and CHEN [4,6,7] found that the pores......
In-situ formation of Ni-Al intermetallics-coated graphite/Al composite in a cold-sprayed coating and its high temperature tribological behaviorsChunjie Huang1,Wenya Li2,Marie-Pierre Planche1,Hanlin..., Northwestern Polytechnical University摘 要:In this study, cold spraying(CS) was used to deposit a mixture of nickel-coated graphite and 40 vol.% Al powder(Ni-Gr/Al......

as follows: Ni, 33%; Al, 33%; Cr, 28%; Mo, 5.0%-5.8%; Hf, 0.2%-1.0%. The action of Hf addition is for solid solution strengthening and dispersion strengthening. In this study.... For IC alloy, no obvious precipitates were observed in NiAl phase and Cr(Mo) phase, even for coarser primary NiAl phase by SEM in spite of greater solubility of Cr, Mo and Hf in NiAl phase and Ni......
