Nanocrystalline　Ni　and　Ni-Fe　alloy　coatings　were　synthesised　by　brush　plating　using　soluble　anode,　and　the　corrosion　characteristics　of　nanocrystalline　Ni,　Ni-5·84%Fe　and　Ni-13·49%Fe　were　investigated　by　soak　method　and　electrochemical　polarisation　method　respectively.　The　nanocrystalline　Ni-Fe　alloy　coatings　showed　higher　hardness　and　smaller　grain　size　than　that　of　Ni　coating.　Ni-13·49%Fe　alloy　coating　exhibited　better　corrosion　resistance　in　3·5　wt-%　NaCl　solution　than　the　nanocrystalline　Ni　coating　and　the　Ni-5·84%Fe　coating,　which　indicats　that　the　corrosion　resistant　of　nanocrystalline　Ni　coating　can　be　improved　by　adding　appropriate　amount　of　Fe.　©　2011　Institute　of　Materials,　Minerals　and　Mining.
