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...

15 August 2008 Abstract The intermetallic compounds PdGa and Pd3Ga7 are introduced as selective catalysts for the hydrogenation of acetylene. Single phase PdGa and Pd3Ga7 can readily be prepared by the appropriate thermal treatment of the stoichiometric mixtures of the corresponding elements. The initial low surface areas of the as-prepared materials can be increased by careful mechanical treat...

Monodispersed intermetallic AuCu pentagonal nanorods with controlled size and composition have been developed by a seed-mediated growth route. The AuCu/C nanomaterial catalyzed the coupling reaction of sulfonamide with benzyl alcohol in good to excellent yields.

This study investigated the interfacial microstructure between gold-coated titanium and low-fusing porcelain. The square surfaces of cast titanium split rods were sputter-coated with gold using a sputter coater at 40 mA for 1,000 seconds. Specimens were prepared for transmission electron microscopy (TEM) by cutting and polishing two pieces of the gold-coated split-rod specimens, which were glue...

In bi- and trimetallic Pt-bipyridine-acetylide/Ru-bipyridine complexes the intermetallic Pt-Ru distance is approximately 9 è, and complete Pt-->Ru energy transfer is observed with sensitization of the Ru-based luminescence.

REAu4Al8Si (RE = Ce-Gd, and Yb) is the end member of a new series of intermetallic structures grown from aluminium flux; this new structure contains thick AuAl2 slabs and the ytterbium analog exhibits mixed-valent behavior.

A non-intermetallic PtPb/C catalyst of hollow structure is synthesized through a simple reduction method, and exhibits an activity as high as 3.6 times that of commercial Pd black and a much higher stability for electrooxidation of formic acid.
