摘要:
Substantially defect-free titanium aluminide components and methods are provided for manufacturing the same from articles formed by consolidation processes. The method includes providing an intermediate article comprised of a titanium aluminide alloy and formed by a consolidation process. The intermediate article is encapsulated with an aluminum-containing encapsulation layer. The intermediate article is compacted after the encapsulation step. A substantially defect-free titanium aluminide component comprises a compacted three-dimensional article comprised of titanium aluminide and formed by a consolidation process and an aluminum-containing encapsulation layer on at least one surface of the compacted three-dimensional article. The aluminum-containing encapsulation layer comprises an aluminide material, MCrAlY wherein M is cobalt, nickel, or a combination of cobalt and nickel, or TiAlCr.

The disclosed embodiments generally relate to non-destructive evaluation methods. In an embodiment, a method for non-destructive evaluation of a aerospace component includes positioning a first plurality of sensors in the region of interest, positioning a second plurality of sensors in the region of interest, inducing a vibration in the region of interest using the first plurality of sensors and receiving a resonance frequency spectra using the second plurality of sensors, and comparing the received resonance frequency spectra against a reference spectra to determine the presence of an anomaly in the region of interest.
摘要:
A method of coating articles comprises providing a plurality of coating dispensing devices at each station in a coating material application line, each device being connected to a common source of coating material. Coating material is dispensed fron only one device while measuring the flow rate of coating material therethrough. When the measured flow rate falls below a predetermined threshold, flow through the device is automatically terminated and switched to another device. Apparatus for practicing the method includes a plurality of dispensing devices connected to a common coating source through respective flow rate sensors. A programmable logic control station connected to the sensors and the devices is used to control the operation of the dispensing devices.
