| Abstract: | Ten different Ni-5wt.%Al powders—three clad, done sintered, three water atomized, and three gas atomized—have been evaluated
and plasma sprayed. The study focused on how manufacturing method, chemical composition, and particle size distribution of
the powders affect the quality of the coating. Properties such as microstructure and mechanical behavior, as well as oxidation
and corrosion resistance, are discussed. In conclusion, recommendations concerning the selection of powders for different
applications are presented. |
