A method of depositing a bimetallic alloy coating onto a bare stainless-steel bipolar plate includes preheating the bare stainless-steel bipolar plate to a temperature ranging from 450° C. to 500° C. Further, the method includes depositing copper (Cu) and nickel (Ni) onto the bare stainless-steel bipolar plate to form a coated stainless-steel bipolar plate. Furthermore, the method includes cooling the coated stainless-steel bipolar plate after terminating the depositing. The deposition is an aerosol assisted chemical vapor deposition of Cu and Ni from a solution containing a mixture of a copper (II) precursor and a nickel (II) precursor for 1 hour (h) to 3 h to form the coated stainless-steel bipolar plate having a coating including a CuNi film having a metal phase including Cu, Ni and CuNi.

A method to form a metal matrix composite reinforced with eggshell (ES). The method includes preparing an ES powder, blending and milling the ES powder with at least one metal powder selected from the group consisting of magnesium (Mg), zirconium (Zr) to form a powder mixture, compacting and sintering the powder mixture to form the metal matrix composite. In addition, a Mg—Zr-ES metal matrix composite with improved corrosion resistance, having an amount of magnesium from 95 to 97 wt. %, an amount of zirconium from 1 to 2 wt. %, and an amount of ES from 1 to 4 wt. %, may be used for biomedical applications.

A saltwater corrosion resistant composite coating is described. The coating includes at least one conductive polymer, chitosan, reduced graphene oxide (rGO), and a cured epoxy. The rGO and chitosan are dispersed in particles of the conductive polymer to form a 3D network. At least a portion of the chitosan is covalently bound to the rGO. At least a portion of the conductive polymer is covalently bound to the chitosan, and the 3D network is dispersed in the cured epoxy.
