“…although the corrosion of sulfur on steel in the alkaline solution has been studied by many scholars, most of them mainly focus on the corrosion of steel in white liquor, which contained the highest concentrations of alkaline and sulfur-contained species. esteves et al [7] studied the cyclic potentiodynamic polarization behavior of two steels in white and green liquors from a pulp processing plant. Feng, et al [8] evaluated the effect of temperature on the corrosion behavior of S32750 steel in white liquor.…”

Study on CorroSion Behavior of Q235 Steel and 16Mn Steel By eleCtroCheMiCal and Weight loSS MethodThis study investigates the corrosion characteristics of Q235 steel and 16Mn steel in the sulfur-containing alkaline solution. The composition and the morphology of the corrosion products were analyzed by XpS and SeM respectively. The electrochemical behavior of Q235 steel and 16Mn steel was evaluated by potentiodynamic polarization curve and eiS. The results indicated that the corrosion rate of Q235 steel is greater than 16Mn steel in the early corrosion. pitting and selective corrosion appeared on the surface of the two steels, and the surface product layer was granular and defective. XpS and eDS indicate that the structurally stable iron oxide is formed on the surface of the two steels. electrochemical results show the corrosion kinetics of Q235 steel and 16Mn steel are simultaneously controlled by the charge transfer and ion diffusion, and the formation mechanism of corrosion products was clarified.

The present article focuses on the electrical discharge treatment of duplex stainless steel (DSS-2205) to enhance its biological responses and corrosion resistance. Electrical discharge machining (EDM) was executed at different spark energy levels (by varying input factors) and 18 different morphological DSS substrates were prepared according to the L18 experimental array. Further, an electrochemical potentiodynamic test was performed on the unmachined and treated surfaces to investigate the corrosion performance. Moreover, the high corrosion resistance substrates along with untreated specimen were further analyzed for the in-vitro interaction with human red blood cells. The results claimed that the surface treatment by EDM significantly enhances the corrosion resistance (< 90%) as well as the biological responses of DSS alloy. The current of 10A, on-time = 60 µs, off-time = 150 µs, machining with W-Cu electrode in deionized water was witnessed as the best set of parameters in both corrosion and hemocompatibility test. Thus, surface alteration of DSS-2205 by EDM can be believed as a promising technique for improving the corrosion resistance and biological responses that essential for biomedical applications.
