    Abstract: A method and apparatus for microplasma spray coating a portion of a turbine vane without masking any portions thereof. The apparatus includes a microplasma gun with an anode, cathode, and an arc generator for generating an electric arc between the anode and cathode. An arc gas emitter injects gas through the electric arc. The electric arc is operable for ionizing the gas to create a plasma gas stream. A powder injector injects powdered material into a plasma stream. A localized area of the turbine vane is coated with the powdered material without having to mask the turbine vane.

    Abstract: A method of applying a wear-resistant coating comprises mixing about 75% to about 85% by weight chromium carbide and about 15% to about 25% by weight nickel chromium to form a chromium carbide-nickel chromium mixture, and simultaneously heating the chromium carbide-nickel chromium mixture to about 1371 degrees Celsius to about 2204 degrees Celsius and applying the chromium carbide-nickel chromium mixture at a velocity in a range of about 305 meters feet per second to about 915 meters per second by high velocity oxygen fuel (HVOF) spraying.

    Abstract translation: 施加耐磨涂层的方法包括混合约75重量%至约85重量%的碳化铬和约15重量%至约25重量%的镍铬,以形成碳化铬 - 镍铬混合物,并同时加热碳化铬 镍镍混合物至约1371摄氏度至约2204摄氏度,并以高速氧燃料(HVOF)以约305米/秒至约915米每秒的速度施加碳化铬 - 镍铬混合物, 喷涂。
