Microstructure evolution and corrosion behavior of the Incoloy 028 alloy upon aging
Source abstract
Abstract
This study investigates the microstructural evolution, electrochemical behavior, and passive film formation of Incoloy 028 alloy during immersion in simulated oilfield solution. The results show that higher aging temperatures lead to increased precipitate formation, which deteriorates the corrosion resistance. Mott-Schottky analysis indicates that the passive films exhibit both n-type and p-type semiconductor behavior, with decreasing donor and acceptor densities at higher aging temperatures, suggesting improved film stability. XPS analysis reveals that the formation of Cr and Mo compounds enhances film densification.
