Enhancing Steam Oxidation Resistance of Ferritic Steels through Formation of Nickel Aluminide Diffusion Coatings at Low Temperatures

A nickel aluminide coating was formed on P92 steel substrate using a two step process of electro-Ni plating followed by pack aluminising at 650 °C. The coating was tested in 100% steam to assess its resistance against steam oxidation at 650 °C using a purpose-built rig for steam oxidation tests. The data obtained were compared with those measured from air oxidation test at the same temperature. It was revealed that steam is a more severe oxidising environment than air for the coating. Oxidation kinetics and degradation mechanisms affecting the lifetime of the coating were discussed.

Work Up

Trimesitylstibane (1) reacts with SbCl3 or SbBr3 to form the halostibanes Mes2SbCl (2), MesSbCl3 (3), Mes2SbBr (4). or MesSbBr2 (5) [Mes = 2,4,6-(CH3)3C6H2]. Action of MesMgCl on an excess of SbCl3 or SbBr3 at low temperatures gives Mes3SbCl2 (6) or Mes3SbBr2 (7), resp. Addition of Br2 to 1 gives 7 in 96% yield. The silylstibanes Mes2SbSiMe3 (8) and McsSb(SiMc3)2 (9) are formed by dehalogenation of Me3SiCl and 4 or 5 by Mg filings in tetrahydrofuran. Mes2SbOSiMe3 (10) is obtained by air oxidation of 8. Reduction of 4 with Mg gives Mes2SbSbMes2 (19). Crystals of the composition (MesSb)6·C6H6 (13a) or (MesSb)4·C6H5CH3 (13b) are obtained from Mg and 5 after work-up in benzene or toluene, resp.
