Abstract：

The　effect　of　the　anode　potential　on　the　electrochemical　performance　and　protective　ability　of　the　passive　film　formed　on　the　brass　alloy　in　the　soil　solution　of　the　Zhouyuan　site　was　investigated　by　electrochemical　measurements,　atomic　force　microscopy,　and　X-ray　photoelectron　spectroscopy.　The　corrosion　resistance　of　brass　alloy　in　a　corrosion　soil　environment　decreases　with　the　increase　of　applied　anodic　potential.　X-ray　photoelectron　spectroscopy　results　indicate　that　the　passive　film　is　mainly　composed　of　metal　oxide.　Mott–Schottky　results　revealed　that　the　passive　films　behave　as　p-type　semiconductors　at　passive　potentials　and　the　acceptor　density　is　in　the　range　of　1021　cm−3　and　increased　with　an　increase　in　the　film-forming　potential.　©　2021　Wiley-VCH　GmbH
