Abstract:
A coating apparatus comprises a coating chamber for coating the articles. The at least one preheat chamber is coupled to the coating chamber. The at least one loading station has a proximal end connectable to at least one of the preheat chambers when in an installed position at a distal end of the preheat chamber. The loading station further includes a carrier for carrying the articles and a drive system. The drive system is positioned to move the carrier between: a loading/unloading position of the carrier in the loading station; a preheat position of the carrier in the preheat chamber to which the loading station is connected; and a deposition position of the carrier in the coating chamber. A gas source is connected to the preheat chamber.

Abstract:
A method of bonding a titanium article to another metal article using a superplastic interlayer is disclosed. A fine-grain titanium alloy interlayer is provided between faying surfaces of the articles to be bonded. The interlayer has an alpha-beta microstructure and an average grain size of less than about 1-3 microns (.001-.003 mm) in at least one plane. The articles to joined and the interlayer are heated to between 1000 °F (538 °C) and 1500 °F (816 °C). A sufficiently large compressive force is then applied to the articles to cause superplastic deformation of the interlayer and bonding of the articles.
