    摘要： A blade (10) for a rotor of a wind turbine having a profiled contour divided into: a root region (30), an airfoil region (34), and a transition region (32) between the root region (30) and the airfoil region (34). A shoulder (40) is located at the boundary between the transition region (32) and the airfoil region (34). The blade's profiled contour comprises a local relative thickness defined as the local ratio between a maximum profile thickness (t) and the chord length (c). The ratio between the shoulder width (W) and the blade length (L) being less than or equal to 0.075, and the relative thickness (t/c) in a blade length interval of 0-0.8L is at least 22%.

    摘要： Ferrous metal or titanium or aluminum is coated with a mixture of phosphoric acid, chromic acid and magnesium salts of these acids, as well as with aluminum flakes, or coated with a mixture of aluminum flakes and magnesium chromate or dichromate, to provide after baking excellent resistance to attack. Aluminum-silicon alloys containing about 10 to about 15 weight percent silicon give better results than ordinary aluminum, particularly when the aluminum is in powder form; and when coated products are given a burnishing treatment. Very good masking for pack diffusion aluminizing or chromizing on any metal to keep portions from being diffusion coated is effected by localized coating, the lowest layer of which is depletion-reducing. The upper coating layer can be of non-contaminating particles like nickel or Cr.sub.2 O.sub.3 that upon aluminizing or chromizing become coherently held together to form a secure sheath. Such sheath can also be used for holding localized diffusion-coating layer in place. Low-alloy steels are made resistant to hot sulfidation by first decarburizing then chromizing then aluminizing, either in independent operations or run together in a single retort.

    摘要： Chromized nickel- and cobalt-based superalloys have alphachrome phase formed during chromizing, and the amount of that phase is diminished by one or more treatments with alkali-permanganate solution and intervening removal of permanganate reaction product film as by acid dip. A kit of such solutions can be prepared. Low-alloy steel steam boiler tubing can have chromized interior and aluminized exterior, and long lengths chromized without a perfectly sealed retort around it can have end caps fitted with extra pack to reduce oxygen penetration to interior. Chain saw cutter blades can be chromized and carburized. Stripping of aluminized coatings from super-alloys with fluoride-containing nitric acid solution is improved by follow-up treatment with fluoride-free nitric acid solution. Smut that forms on ferrous surface during cleaning is chemically removed by first depositing a nickel flash plating on smut-containing surface, and then dissolving the nickel plating by treatment with aqueous nitric acid containing a little halide ion.

    摘要： Diffusion coatings can be masked from portions of a workpiece by combination of layers, the outer one of which forms coherent strong shell that holds inner layer or layers in place. All ingredients of these layers can be materials such as nickel, nickel aluminide, chromium, chromic oxide (Cr.sub.2 O.sub.3) and inert diluent that do not contaminate superalloys or even low alloy or plain carbon steels. Such a holding shell can also be used to retain on a workpiece surface a layer that causes formation of a diffusion coating. Low alloy steel conduit can be internally chromized and/or externally chromized or aluminized to make it more desirable for use as high pressure steam boiler heat exchange tubing. Nickel articles aluminized with deep Ni.sub.2 Al.sub.3 layer that has outer skin more heavily aluminized can have aluminum correspondingly leached out from outer skin only.
