    摘要： A single crystal alloy for high AN2 applications has a composition consisting essentially of from 4.0 to 10 wt % chromium, from 1.0 to 2.5 wt % molybdenum, up to 5.0 wt % tungsten, from 3.0 to 8.0 wt % tantalum, from 5.5 to 6.25 wt % aluminum, from 6.0 to 17 wt % cobalt, up to 0.2 wt % hafnium, from 4.0 to 6.0 wt % rhenium, from 1.0 to 3.0 wt % ruthenium, and the balance nickel. Further, these single crystal alloys have a total tungsten and molybdenum content in the range of from 1.0 to 7.5 wt %, preferably from 2.0 to 7.0 wt %, a total refractory element content in the range of from 9.0 to 24.5 wt %, preferably from 13 to 22 wt %, a ratio of rhenium to a total refractory element content in the range of from 0.16 to 0.67, preferably from 0.20 to 0.45, a density in the range of from 0.300 to 0.325 lb/in3, and a specific creep strength in the range from 106×103 to 124×103 inches. These alloys provide (a) increased creep strength for a given density and (b) specific creep strengths as high as or higher than all 2nd generation single crystal alloys with a significant decrease in density.

    摘要： The present invention relates to a method for repairing turbine engine components, such as vanes and blades, which have airfoils. The method broadly comprises removing oxidation debris from portions of the component by blending areas exhibiting thermal barrier coating spall and/or oxidation damage, removing a ceramic insulating layer from the component, and blending surfaces of the component where nicks, dents, and/or cracks are located. If the component has a depleted aluminum zone, the depleted zone is either removed or replenished. Further, a tip portion of the component, if damaged, is restored and tip abrasives are applied to restore the component's cutting ability. Thereafter, a ceramic coating is applied to the component.
