Corrosion Rate of Steel in Liquid Zn, Zn-Bi and Zn-Sn Baths

چکیده
In the hot dip galvanizing process, steel products are immersed in a liquid zinc bath. The contact of with causes corrosion as result Fe dissolution processes liquid. If process is carried out controlled manner, it results formation coating. Uncontrolled leads to degradation surface. This article presents research into influence Bi and Sn additions baths on zinc. Corrosion tests were under conditions kinetic using rotating disc method. constants different Si contents Zn, Zn-0.5Bi Zn-2Sn determined. It was found that addition lowers value constant may act an inhibitor Based measurements determined constant, activation energy temperature range 440–480 °C, increases energy, which reduces intensity transfer

Liquid Metal Corrosion of 316L, Fe3AI, and FeCrSi in Molten Zn-AI Baths
Corrosion tests of 316L and two intermetallic compounds Fe3AI and FeCrSi in industrial Galvanizing (Zn-0.18Al), GALFAN (Zn-5AI), GALVALUME (Zn-55AI), and Aluminizing (AI-8Si) baths and lab-scale static baths were conducted. In on-line tests in industrial hot-dip baths, 316L steel shows better corrosion resistance than Fe3AI in Galvanizing, GALFAN, and GALVALUME baths. The corrosion resistance o...
متن کاملCorrosion Protection of Steel Using Nonanomalous Ni-Zn-P Coatings
A novel technique for obtaining nonanomalous Ni-Zn-P coatings with high Ni content ~74 wt % as compared to 15-20 wt % in the conventional plating method! has been developed. These coatings show promise as a replacement for Cd in sacrificially protecting steel. Ni-Zn-P coatings were deposited using an electroless method from a solution containing NiSO4 , complexing agent and ammonium chloride. V...
متن کاملElectrodeposition and Characterization of Sn-Zn Alloy Coatings from Sulfate Based Baths
Tin-Zinc alloy coatings have many applications because of their unique properties such as corrosion resistance, solderability and flexibility. In this study, the effect of current density, temperature and pH on chemical composition, cathodic current efficiency, morphology and structures of the coatings was investigated. The results illustrated that, at low current densities (<0.5 mA/cm2), the c...
متن کاملThe Enthalpies of Mixing of Liquid Ni-Sn-Zn Alloys
The partial and integral enthalpies of mixing of liquid ternary Ni-Sn-Zn alloys were determined. The system was investigated along two sections xNi/xSn ≈ 1:9, xNi/xSn ≈ 1:6 at 1073 K and along two sections xSn/xZn ≈ 9:1, xSn/xZn ≈ 4:1 at 873 K. The integral enthalpy of mixing at each temperature is described using the Redlich-Kister-Muggianu model for substitutional ternary solutions. In additi...
