摘要： A new method for increasing the durability of a turbine engine is provided. The method utilizes a cold gas-dynamic spray technique to apply wear resistant materials to turbine blades. These wear resistant materials improve the durability of the turbine blades, and thus can improve the overall durability, reliability and performance of the turbine engine themselves. In the cold gas-dynamic spray process particles at a temperature below their fusing temperature are accelerated and directed to a target surface on the turbine blade. When the particles strike the target surface, the kinetic energy of the particles is converted into deformation of the particle, causing the particle to form a strong bond with the target surface. Post-spray processing is then performed to consolidate the coating materials and restore material properties in the turbine blade. Thus, the cold gas-dynamic spray process can apply a coating of wear resistant materials to the turbine blades.
摘要翻译：提供了一种用于增加涡轮发动机的耐久性的新方法。该方法利用冷气动喷雾技术将耐磨材料应用于涡轮叶片。这些耐磨材料提高了涡轮叶片的耐久性，从而可以提高涡轮发动机本身的整体耐久性，可靠性和性能。在冷气体动态喷雾过程中，低于其定影温度的温度下的颗粒被加速并引导到涡轮叶片上的目标表面。当颗粒撞击目标表面时，颗粒的动能转化为颗粒的变形，导致颗粒与目标表面形成牢固的结合。然后进行后喷雾处理以固结涂层材料并恢复涡轮叶片中的材料性质。因此，冷气体动态喷涂工艺可将耐磨材料涂层施加到涡轮叶片上。

摘要： In a method for coating a surface of a turbine component with an environment-resistant aluminide, a coating is formed by cold gas-dynamic spraying a powder material on the turbine component surface, the powder material comprising aluminum, platinum, and at least one additional metal selected from the group consisting of nickel, chromium, hafnium, silicon, yttrium, rhenium, zirconium, cobalt, and tantalum. After forming the coating, at least one thermal diffusion treatment is performed on the turbine component to metallurgically homogenize the coating and thereby form an aluminide coating that includes by weight about 12 to about 30% aluminum, up to about 50% platinum, about 2 to about 25% chromium, about 1 to about 5% hafnium, about 1 to about 5% silicon, about 0.1 to about 1% yttrium, and about 1 to about 3% Zr, and nickel.

摘要： A new method for repairing turbine engine components is provided. The method utilizes a cold gas-dynamic spray technique to repair degradation on turbine blades, vanes and other components. In the cold gas-dynamic spray process particles at a temperature below their fusing temperature are accelerated and directed to a target surface on the turbine blade. When the particles strike the target surface, the kinetic energy of the particles is converted into plastic deformation of the particle, causing the particle to form a strong bond with the target surface. Post-spray processing is then performed to consolidate and homogenize the applied materials and restore integrity to the material properties in the repaired turbine component. Thus, the cold gas-dynamic spray process and post-spray processing can be employed to effectively repair degraded areas on gas turbine components.

摘要： There is provided a method for applying an improved chromium diffusion coating on an industrial item such as a turbine blade of a gas turbine engine. Chromium and other active metals are combined to form an alloy coating. Active elements include silicon, hafnium, zirconium, yttrium, tantalum, and rhenium. For producing the modified coatings through pack cementation chromium and a master alloy are mixed into a packing along with inert material and a halide activator. The packing surrounds a target in a diffusion box. The metals are then deposited by diffusion onto a target surface by pack cementation methods. The diffusion of the desired metals takes place during a coating thermal cycle. Alternatively, the diffusion can take place using an out-of-pack arrangement. Such modified coatings are utilized as improved performance coatings for environmental resistance applications over the current chromium diffusion coatings.

摘要： The present invention provides a chromium and active elements modified platinum aluminide coating that may be used on a surface of a gas turbine engine component such as a turbine blade. The coating may be used as a protective coating that impedes the progress of corrosion, oxidation, and sulfidation in superalloy materials that comprise the substrate of the turbine blade. Additionally, the coating may be used as a bond coat onto which a thermal barrier coating is deposited. The presence of active elements as well as chromium and platinum provides improved corrosion, oxidation, and sulfidation resistance. The coating is applied using an electron beam physical vapor deposition. The coating is applied alternatively using selected sequential diffusion processing steps involving chromium, platinum and aluminum.
