Nanocrystalline　nickel　and　Ni-Fe　alloy　coatings　were　synthesized　by　brush　plating　using　soluble　anode.　The　corrosion　characteristics　of　nanocrystalline　nickel,　Ni-5.84%Fe　and　Ni-13.49%Fe　alloys　were　investigated　by　soak　a　method　and　an　electrochemical　polarization　method,　respectively.　The　experimental　results　indicate　that　the　typical　nanocrystalline　nickel　and　Ni-Fe　alloy　coatings　can　be　synthesized　by　brush　plating,　and　the　alloying　element　Fe　has　the　effects　of　solution　strengthening　and　grain　size　refinement.　The　nanocrystalline　Ni-13.49%Fe　alloy　is　dense　in　nature　and　pore　free,　and　exhibits　better　corrosion　resistance　in　a　3.5　wt%　NaCl　solution　than　the　nanocrystalline　nickel.　In　10　wt%　HCl　solution,　the　nanocrystalline　Ni-13.49%Fe　alloy　also　shows　a　good　corrosion　resistance　as　the　nanocrystalline　nickel.　The　surface　morphology　of　all　samples　after　corrosion　show　a　spot　corrosion　feature　in　3.5　wt%　NaCl　solution,　however,　the　samples　are　uniformly　corroded　in　10　wt%　HCl　solution.　©　2009,　Northwest　Institute　for　Nonferrous　Metal　Research.　Published　by　Elsevier　BV.　All　rights　reserved.
