    摘要： An outwardly grown diffusion aluminide bondcoat is formed on a superalloy substrate and has higher concentrations of Al and Pt and lower concentrations of harmful impurities (e.g. Mo, W, Cr, Ta, S, etc.) at an outermost region of the bondcoat than at an innermost region thereof adjacent the substrate. The bondcoat is pretreated prior to deposition of a ceramic thermal insulative layer in a manner that reduces grain boundary ridges on the outermost bondcoat surface without adversely affecting the outermost region thereof, and then is heat treated to thermally grow a stable alpha alumina layer on the bondcoat prior to deposition of a ceramic layer.

    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.

    摘要翻译： 用于钻井管的磨损带，其由螺旋弹簧构成，螺旋弹簧的尺寸适于装配在井钻管或套管的接头处。 螺旋弹簧的内表面包括纹理化涂层，例如碳化物。 外表面包括限定在其中的多个流体动力学凹坑，并且优选地，外表面和内表面都适于抵抗腐蚀。 研磨涂层优选基本上由95％碳化钨和5％钴的粘合剂组成，并且涂覆一定量的内表面在50％至100％的范围内。 流体动力学凹坑的形状通常为泪滴，用作微型流体泵。 因此，磨损带可以机械连接到钻杆，同时不需要冶金焊接的硬带，因此不影响钻杆的性能和尺寸。
