In-situ formation of Ni-Al intermetallics-coated graphite/Al
发布时间：2023-04-21 21:59
In this study, cold spraying(CS) was used to deposit a mixture of nickel-coated graphite and 40 vol.% Al powder(Ni-Gr/Al) on a steel substrate aiming to effectively preserve a certain volume fraction of graphite in the deposited Ni-Gr/Al composite coating. The microstructure of the as-sprayed coating and the effect of post-spray heat-treatment(PSHT) temperatures on the in-situ formation of Ni-Al intermetallic phases in coating were studied. The tribological behaviors of the as-sprayed coating an...
