Accelerated corrosion behavior of DD32 alloy in the marine atmospheric environment
Source abstract
Abstract
The corrosion of DD32 alloy in a marine atmospheric environment was investigated through accelerated corrosion tests. The corrosion morphology and products of alloy were discussed by the SEM, XRD, and XPS characterization. Under marine atmospheric corrosion, corrosion pits formed on the alloy surface. As time progressed, these pits deepened and coalesced into elongated pits, resulting in a reduction of the alloy's corrosion resistance. The main corrosion products on the surface were in terms of Al2O3, Cr2O3, NiO, and NiCr2O4. In addition, the electrochemical behavior of DD32 alloy before and after corrosion was further analyzed with the polarization curve and the impedance spectrum. The results indicated that the corrosion resistance of the corroded alloy decreased and the thickness of the passive film decreased from 0.65 nm before corrosion to 0.38 nm. Under marine atmospheric environmental conditions, the corrosion of alloy was affected by active oxygen, and the corrosion process occurred cyclically, reducing the alloy's corrosion resistance. This study provides guidance for the application of nickel - based single crystal alloy in marine atmospheric environments.
