The　electrolytic-accelerated　corrosion　behavior　of　brass　alloys　imitating　the　Western　Zhou　Dynasty　in　an　archeological-corrosive　medium　were　investigated　by　electrochemical　measurements　and　microscopy　observations.　The　results　indicated　that　the　increase　of　copper　content　improved　the　corrosion　resistance　of　the　alloys　in　the　archeological-corrosive　medium.　The　corrosion　mechanism　of　brass　alloys　in　this　corrosive　medium　is　controlled　by　a　mixed　corrosion　with　selective　dissolution　and　dissolution-reduction.　Chloride　ions　are　bound　to　affect　the　dissolution　behavior　of　the　alloy.　The　corrosion　products　formed　on　the　alloy　surface　is　mainly　composed　of　copper　oxide　and　insoluble　copper　chloride.　©　2021　Elsevier　B.V.
