Abstract: A method for increasing corrosion resistance of metallic substrates without use of hexavalent chromium includes chemically treating the substrate to create an oxide layer, mixing graphene nanoplatelets into a non-chromate epoxy-based primer, applying the primer to the oxide layer of the substrate, and applying a topcoat to the primer opposite the oxide layer.

Abstract: A gear pump can include at least one gear having a plurality of gear teeth. At least the plurality of gear teeth can be additively manufactured and can include a substrate and a pitting resistant outer coating additively manufactured on the substrate and configured to prevent pitting due to cavitation. The substrate can include a substrate material and the pitting resistant outer coating includes a pitting resistant material different than the substrate material. The pitting resistant outer coating defines an outer surface layer of the gear teeth.

Abstract: A method of applying a hydrophobic surface coating to one or more internal surfaces of a fluid passage component, the method including: flowing a rare earth precursor into the fluid passage component; allowing the rare earth precursor to react with the one or more internal surfaces of the fluid passage component; removing excess rare earth precursor from the fluid passage component; flowing an oxide forming precursor into the fluid passage component; allowing the oxide forming precursor to react with the rare earth precursors on the one or more internal surfaces to form a hydrophobic surface coating on each of the one or more internal surfaces; and removing excess oxide forming precursor from the fluid passage component.
