    摘要: A gas turbine engine includes: a turbine section including a casing extending circumferentially about a plurality of turbine blades and having at least one seal member coated with an abradable coating. At least one turbine blade has sides and a tip and at least one seal member is located adjacent to the tip of the at least one turbine blade. The tip of the at least one turbine blade has a wear resistant layer and an abrasive coating disposed on the wear resistant layer. The wear resistant layer has a thickness less than or equal to 10 mils (254 micrometers) and includes metal boride compounds.

    摘要: A gas injector including in which a gas is passed through high-voltage/low-current electrical discharges before being discharged into the chamber of a thermal treatment furnace. The electrical activation of the gas accelerates desirable reactions between the gas, gases in the furnace chamber, and the chamber workload. Preferably, a hot electrode is electrically charged and the other parts of the gas injector and the furnace are grounded.

    摘要: A coated article and method for manufacturing the same wherein an alloy substrate of iron, nickel, cobalt, or titanium base has a diffusion layer formed thereon of an intermetallic boride of the substrate alloy. A coating is subsequently deposited on the diffusion layer, which coating is a refractory, ceramic or intermetallic compound having desired wear and/or corrosion resistant properties superior to those of the substrate.

    摘要: A process is provided for boriding metals and metal alloys in a fluidized bed at a temperature of from about 580.degree. to about 1300.degree. C. As a boriding agent, there was used a granular material comprising essentially spherical particles having a particle size of from about 0.025 to about 5.00 mm, which granular material was manufactured by spray drying a preferably aqueous suspension or dispersion based on materials that yield boron, and which can contain fillers, extenders and binders.
