MATERIAL - BRAZING ALLOYS - TITANIUM ALLOY JOINING WETABILITY AND EROSION CHARACTERISTICS
Abstract
Brazing tests involving titanium honeycomb core joined to various titanium alloy face plates ranging 0.015 to 0.031 in. thickness with an eutectic composition silver-copper brazing alloy, (BT alloy, 72% silver - 28% copper). Heating the BT alloy to its flow point (1435 F) in contact with the various titanium alloys and in the pres ence of an inert atmosphere showed that lithium additions to the brazing alloy and nickeled plating on the titanium alloys was not necessary to achieve good flows and wetability. This was attributed to the ability of titanium to absorb its own oxide at temperatures above 1300 F, a situation in which titanium alloys appear to possess a certain self-cleaning capability in the presence of inert atmospheres and moderate oxide coatings.
