  • Chemical milling using an inert particulate and moving vessel
    Patent number: 4563239
    Abstract: Thin edged workpieces are chemically milled to remove material uniformly from their surfaces by tumbling the workpieces in a barrel in which is contained a sufficient volume of inert polymer particulate media. Titanium airfoils for turbomachinery are able to have an oxidized surface layer removed without suffering small nicks and other damage to their critically shaped edges.

  • In situ interlayer formation for transient liquid phase diffusion bonding
    Patent number: 4208222
    Abstract: An interlayer for transient liquid phase diffusion bonding is provided by depositing a metallic coating on at least one of the superalloy surfaces to be bonded and boriding a portion of the metallic coating to form a working coating having an overall composition resembling that of an interlayer alloy and an overall melting temperature less than that of the superalloys. When the superalloy surfaces are placed in contact and heated to above said melting temperature, the partially borided metallic coating functions as an interlayer alloy to effect bonding.
