摘要： A method of making pre-sintered preforms using a mixture of base superalloy particles and titanium-containing boron and silicon free braze alloy particles, such as for the repair of superalloy gas turbine engine components. Alloy particles as large as 2 mm provide reduced shrinkage when compared to prior art preforms. Braze material compositions disclosed herein are boron and silicon free and may have melting temperature ranges as low as 10° C., and they include no element not already present in the composition of the superalloy component.

摘要： A method of manufacturing includes depositing a braze filler adjacent to a void between a first component and a second component thus holding the components in position before brazing. The first and second components are heated to melt and flow the braze filler into the void. A braze joint is formed between the first and second components by cooling the braze filler. Depositing the braze filler can include laser cladding the braze filler to the first and/or second components adjacent the void. The method also optionally includes welding the first and second components in position with the braze filler adjacent to the void. The braze filler may be deposited as a powder, cold spray, melted brazed filament, spherical ball or any other suitable form.

摘要： Alloys comprising titanium as the principal component and which melt between 700 and 1400 degrees C. are disclosed to have favorable characteristics for braze-joining. The alloys form strong, corrosion-resistant braze-joints. They are useful for infiltration and formation of joints between components made of alloys and ceramics of similar and dissimilar compositions.

摘要： The erosion-prone sections of the tubes in a circulating fluidized bed boiler are provided with a locally thickened sidewall without forming discontinuities on the outer surface of the tubes. This can be accomplished, for example, by replacing the erosion prone portion of the tube with a section having a smaller inside diameter, but the same outside diameter, or by replacing the erosion prone portion of the tube with a section having a thicker sidewall, but the same inside diameter, and smoothing over the outside discontinuity with an alloy coating. A useful alloy coating is also disclosed which can be used for this and other applications.

摘要： A laser net shape manufactured BLISK, compressor blade, turbine blade or turbine component including a plurality of overlapping predetermined variable bead widths of a material defining a first material layer, a plurality of overlapping predetermined variable bead widths of a material deposited on top of the first material layer, forming a second material layer; and additional material layers deposited on top of the first material layer and the second material layer. The variable bead width of the deposited material is controlled to maintain the approximately constant percent of bead width overlap. A first 2 to 100 deposited powder layers are deposited by a first laser power and the remaining powder layers are deposited by a laser power that is ramped down over the course of depositing the remaining powder layers. In addition, disclosed is A BLISK, compressor blade, turbine blade or turbine component formed by a method.
