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...

For the first time, this research reports the formation of nanoporous layers of metals on the surface of metal substrates by Raney method and their conversion to corresponding porous perovskite layers. The noble metals doped perovskites are used as catalytic converter for reducing automotive pollutants. The use of perovskite as a substrate for the noble metals can reduce the need for such metal...

Pre-treated low carbon steel specimens with flux or + tin mixture were coated by hot-dip aluminizing process. Al alloy (6061) was melted and hold at 750 °C. Fluxed pre-tinned samples dipped in a molten bath for time intervals of 0.5, 1, 2.5 3.5 min. Applying double coating processes via tinning-aluminizing techniques facilitated the formation Fe-Al intermetallic interface increasing thickness h...

Abstract Among the various surface modification processes, hot-dip aluminizing process has increasingly evoked considerable attention. This method proved to be commercially cost-effective and technically better than galvanizing. In contrast aluminized steel components, galvanized components cannot used in service conditions at elevated temperatures. During last few years, intensive research by ...
