Effect of hydrogen on semiconductive properties of passive film on ferrite and austenite phases in a duplex stainless steel
Abstract Hydrogen effect on semiconductivity and compositions of passive films formed on ferrite and austenite phases in a duplex stainless steel were investigated by current sensing atomic force microscopy and X-ray photoelectron spectroscopy. It is demonstrated that hydrogen significantly increase...
