    摘要： A CVD outwardly grown platinum aluminide diffusion coating on a nickel or cobalt base superalloy substrate wherein the platinum modified aluminide diffusion coating is modified to include silicon, hafnium, and optionally zirconium and/or other active elements (e.g. Ce, La, Y, etc.) each in a concentration of about 0.01 weight % to about 8 weight % of the outer additive (Ni,Pt)(Al,Si) layer of the coating. A particular coating includes about 0.01 weight % to less than 2 weight % of each of silicon, hafnium, and zirconium in the outer additive layer, preferably with a Hf/Si ratio less than about 1 and, when Zr also is present, a Hf+Zr/Si ratio of less than about 1. A coating microstructure is provided characterized by an inner diffusion zone or region adjacent the substrate and the outer additive (Ni,Pt)(Al,Si) layer including hafnium silicide second phase particles or regions dispersed throughout the outer additive layer of the coating.

    摘要： A method of improving the oxidation resistance of a platinum modified aluminide coating formed on a nickel base superalloy substrate, comprises providing a platinum layer on the substrate, heating the substrate in a coating retort to a temperature of at least about 1000.degree. C., forming external of the coating retort a high purity coating gas comprising hydrogen and aluminum trichloride, and introducing the coating gas into the coating retort to contact the heated substrate to form an outwardly grown, single phase [(Ni,Pt)]Al] platinum modified aluminide coating having reduced concentration of at least one of a substrate substitutional alloying element and a surface active tramp element selected from at least one of B, P, and S in said coating as compared to a platinum modified aluminide coating formed at a lower temperature.

    摘要： A wear band for a well drill pipe which is made up of a coil spring sized to fit at the joint of the well drill pipe or casing. The inner surface of the coil spring includes a textured coating such as a carbide. The outer surface includes a plurality of hydrodynamic dimples defined therein, and preferably both the outer surface and the inner surface are adapted to resist corrosion. The abrasive coating preferably consists essentially of 95% tungsten carbide and a binder of 5% cobalt and coats an amount of the inner surface in the range of 50% to 100%. The hydrodynamic dimples are generally tear drop in shape to act as miniature fluid pumps. As a result, the wear band can be mechanically attached to the drill pipe while eliminating the need for metallurgically-welded hardbands and therefore unaffecting the drill pipe properties and dimensions.
