ABSTRACT:
A coating composition and its use in a metallization process that facilitates bonding of brazing filler metals to treated refractory surfaces, such as ceramics. The coating can be applied in preselected areas of the refractory surface to define a target area for brazing. In one embodiment, the coating composition is applied to a refractory material prior to brazing, the composition including (i) a group IVB transition metal component selected from the group consisting of a group IVB transition metal, a hydride thereof, and mixtures of group IVB metals and/or hydrides thereof, (ii) a binder material, and (iii) a fluid carrier, disclosed embodiments, the group IVB transition metal component is titanium, and the binder material is a combination of a styrene block copolymer and a hydrocarbon resin.
