摘要：
Effect of Ti addition on the pitting corrosion behavior of casting duplex stainless steel was studied by means of potentiodynamic measurement and impedance spectroscopy as well as scanning electron microscope (SEM) along with energy-dispersive spectroscopy (EDS) and X-Ray Diffractometer (XRD). It turned out that pitting corrosion occurred mainly on the austenite phase and phase boundaries because of the existence of Cr-rich zone and the precipitation of carbides in the austenite phase and at phase boundaries respectively. Pitting corrosion resistance of duplex stainless steel could be improved through the addition of Ti. © All right reserved.
