The　corrosion　behaviour　study　of　Cu-Pb　alloy　in　simulated　archaeological　soil　environment　were　investigated　using　electrochemical　accelerated　corrosion,　Field　emission　scanning　electron　microscopy/energy　dispersive　spectroscopy,　laser　scanning　confocal　microscope,　X-ray　photoelectron　spectroscopy　and　electrochemical　methods.　It　is　crucial　that　the　corrosion　resistance　of　the　Cu-Pb　alloy　was　found　to　alter　with　the　Pb　content　in　the　alloy.　The　results　demonstrated　that　Cu-13.28Pb　alloy　exhibited　the　best　corrosion　resistance　with　the　smallest　corrosion　current　density　and　the　lowest　anodic　dissolution　rate.　The　corrosion　products　are　mainly　composed　of　matrix　metal　oxides　and　metal-insoluble　inert　compounds.　The　correlation　between　Pb　content　and　corrosion　behaviour　and　the　corresponding　corrosion　mechanism　were　clarified.　©　2021　Elsevier　B.V.
