    摘要： A slurry and a coating method are provided. The slurry includes, by weight, between 10% and 40% metal powder, between 10% and 15% activator, between 10% and 20% adhesive, between 10% and 20% thickener, up to 30% ceramic, and up to 25% binder. The coating method includes providing a slurry including, by weight, between 10% and 40% metal powder, between 10% and 15% activator, between 10% and 20% adhesive, between 10% and 20% thickener, up to 30% ceramic, and up to 25% organic polymer binder, providing a substrate, applying the slurry over a surface of the substrate to form a slurry coating, drying the slurry coating over the substrate, baking the substrate and the slurry coating, and curing the slurry coating over the substrate. The curing the slurry coating over the substrate transfers metal elements of the metal powder in the slurry to the substrate to form a coating on the substrate.

    摘要： Aluminum diffusion can be effected from continuous coatings of leafing-type aluminum particles and such leafing coatings in very thin layers are more effective than coatings of non-leafing aluminum, with or without diffusion. Other protective metals in flake or leaf form can be substituted for or added to the leafing aluminum. Adhesion of the flakes to the substrate is greatly improved and can be effected at lower temperatures if the flakes are applied from a dispersion containing a volatilizable halogen-type carrier or an ammonium chromate. The leafing coatings can be sprayed on from aqueous dispersion containing wetting agents and if desired a polyethylenetrtrafluoroethylene and/or mixtures of phosphoric acid, chromic acid and magnesium, aluminum, calcium or zinc salts of these acids. A protective second coating of such mixtures can be applied as a cover layer over the layer containing the leafing aluminum, and this combination works best on a ferrous metal that has an aluminum diffusion coating, particularly a ferrous metal that contains less than 1% chromium and has such an aluminum diffusion coating. It also works very well on aluminum diffusion coatings from packs containing chromium, or chromium and silicon, in addition to the aluminum, and these alloys can be made by magnesothermic reduction of their mixed oxides or the like. The aluminum diffusion can also be made from a pack containing cobalt with or without a little chromium, and this forms a particularly desirable diffusion coating on nickel-base alloys. Aluminum diffusion coatings can be kept from undesired locations by covering those locations with an Ni.sub.3 Al-type masking layer containing thermoplastic resin over which is applied a powdered nickel masking layer containing thermoplastic resin. On firing this masking combination forms a strong shell that effectively masks without contaminating the surrounding coating pack.

    摘要翻译： 铝扩散可以由叶片型铝颗粒的连续涂层实现，并且非常薄的这种叶片涂层比具有或不具有扩散的非漂浮铝的涂层更有效。 片状或叶状的其他保护金属可以替代或添加到叶片铝中。 如果从包含可挥发的卤素型载体或铬酸铵的分散体中施加薄片，则薄片对基材的粘合性大大提高并且可以在较低温度下进行。 可以从含有润湿剂的含水分散体和如果需要的话，将这种酸的聚乙烯三氟乙烯和/或磷酸，铬酸和镁，铝，钙或锌盐的混合物喷洒在叶片上。 这种混合物的保护性第二涂层可以作为覆盖层施加在含有漂浮铝的层上，并且这种组合对具有铝扩散涂层的黑色金属，特别是含有少于1％的铬的黑色金属，以及 具有这样的铝扩散涂层。 除了铝之外，它还可以非常好地用于含有铬或铬和硅的包装的铝扩散涂层，并且这些合金可以通过其混合氧化物等的镁热还原来制备。 铝扩散也可以由含有或不含少量铬的钴组成，并且这在镍基合金上形成特别理想的扩散涂层。 通过用含有热塑性树脂的Ni3Al型掩蔽层覆盖这些位置，可以将铝扩散涂层保持在不期望的位置，在其上涂覆含有热塑性树脂的粉末状镍掩蔽层。 在烧制时，这种掩蔽组合形成了强有力的外壳，有效地遮蔽而不会污染周围的涂料包。

    摘要： An article is provided with improved resistance to hot corrosion through a coating on a metal surface based on an element selected from Fe, Co and Ni, the coating comprising a filled matrix bonded by interdiffusion with the substrate. The matrix is applied by impinging on the substrate metal surface a plurality of heated metallic particles, such as by plasma spraying. The coating includes a filler metal of aluminum and preferably an alloy of aluminum and at least one other element, for example Cr, deposited on and interdiffused with the matrix, such as through a halide vapor deposition process employing a mixture of aluminum powder and other powders. As a result of application of the filler metal, there is provided from the matrix a coating layer of an alloy including an average of about 8-20 weight percent aluminum, the application process resulting in substantial recrystallization of the matrix.

    摘要： Greatly increased thermal fatigue cracking resistance of high temperature resistant base metals such as cobalt and nickel and their alloys used to fabricate jet engine components and like parts is realized by diffusion coating the base metal with chromium, silicon and aluminum in particular proportions to diffuse into the base metal to a uniform depth and distribution between and across intergranular boundaries in the base metal, enabling slowed initiation of thermal fatigue cracking in the diffusion coating as well as reduced corrosion in the base metal.

    摘要： THE METAL PIECES TO BE TREATED ARE EMBEDDED IN A REACTIVE MASS CONTAINED IN A PARTLY GASTIGHT BOX PLACED IN A HEATING VESSEL WHEREIN THERE IS ANAT LEAST PARTLY HYDROGENATED PROTECTIVE ATMOSPHERE. THE REACTIVE MASS COMPRISES AN INTIMATE MIXTURE OF (1) A POWDER ALLOY OF CHROMIUM AND ALUMINUM, (2) AN INERT POWDERED DILUTING COMPONENT AND (3) A HALOGEN-CONTAINING COMPONENT. THE BOX AND ITS CONTENTS ARE HEATED TO 1050*C.-1100*C. FOR A FEW HOURS, THEN COOLED. THE STARTING CHROMIUM POWDER FOR THE CHROMIUM-ALUMINUM ALLOY POWDER MAY BE OF EITHER MAGNESOTHERMIC OR ELECTROLYTIC ORIGIN AND AT LEAST THE ELECTROLYTIC CHROMIUM IS SUBJECTED TO AT LEAST ONE PRETREATMENT, PRIOR TO ALLOYING, BY EXPOSURE TO EITHER MAGNESIUM OR CALCIUM VAPOR TO SUBSTANTIALLY REDUCE THE AMOUNT OF FREE OXYGEN ON AND IN THE CHROMIUM GRAINS.
