摘要： A method for forming a barrier to flow of brazing alloy on the surface or into internal cavities of a component to be treated by brazing. A quantity of stopoff slurry comprising alumina and a polyethylene oxide binder is applied to a surface of the component or into internal cavities of the component. The slurry is dried to set the binder and form a hardened stopoff material on the surface or in the internal cavities to form a barrier to flow of brazing material.

摘要： A method for repairing a recess in an article surface comprises providing first and second metallic powders. The first powder has a first melting temperature and the second powder has a second melting temperature less than the first melting temperature. The first powder is disposed in the recess substantially to fill the recess at least to the article surface. The second powder is disposed over the first powder in an amount that will fill the recess at least to the article surface after melting and flowing the second powder into the recess. The powders are heated to a treatment temperature at least at the second melting temperature and less than the first melting temperature for a time sufficient to melt the second powder, to flow the second powder into the recess about the first powder, and to bond the second powder to a recess surface.

摘要： A final throat area of a gas turbine nozzle circumferential structure is established by providing at least two gas turbine nozzle vanes, and determining a pairwise initial throat area between each pair of gas turbine nozzle vanes. For each pair of gas turbine nozzle vanes whose pairwise initial throat area is not within the final pairwise throat area target range, a trailing edge of at least one of the gas turbine nozzle vanes is extended responsive to the step of determining the initial pairwise throat area, so that a final pairwise throat area is within a final pairwise throat area target range. A nozzle plurality of pairs of gas turbine nozzle vanes that together comprise the gas turbine nozzle circumferential structure may be selected so that a sum of their final pairwise throat areas is within a final total throat area target range. The trailing edge may be extended for this or other purposes by affixing an extension wire to the trailing edge extending lengthwise along the trailing edge, applying a braze material to the extension wire and the trailing edge, and heating the braze material to a brazing temperature to melt at least a portion of the braze material and, upon cooling, to bond the extension wire and the braze material to the trailing edge.
