Abstract
A one step ceramic brazing material preferably for use in joining ceramics to each other or in joining a ceramic to a metal. The brazing material includes a strip of a metal of alloy and greater than 3% titanium or titanium hydride in powder form, in a polymer coating thereon, to enhance the wettability of the braze metal onto ceramics and metals. The brazing material is made in the form of a coated strip so that it can be stamped to washers rings or discs for particular applications.

A brazing product comprising:
- a metal or alloy article of a filler material for forming a braze joint when heated to an appropriate brazing temperature;
- and
- a coating upon at least a portion of the article and comprising a Group IVb transition metal or transition metal hydride and a binder for retaining the transition metal or transition metal hydride upon the article when the coating is applied thereto.
A brazing product comprising:
- a metal or alloy article of a filler metal of at least two metals for forming a braze joint when heated to an appropriate brazing temperature;
- and
- a coating upon at least a portion of the article and comprising a Group IVb transition metal or hydride in powder form and present in an amount of greater than 3 weight percent based on the weight of the alloy article, and a binder of an organic component for retaining the transition metal or hydride upon the article when the coating is applied thereto, the transition metal or hydride powder dispersed substantially uniformly throughout the organic binder and being retained upon the alloy article by the coating, and the binder capable of volatizing when heated to the brazing temperature without substantially interfering with or contaminating the braze joint.
