Research Status and Development Trend of Titanium and Titanium Alloy Brazing Technology
The choice of brazing metal has an important impact on the brazing effect and brazing joint quality.The brazing metal used for titanium and titanium alloy brazing can be divided into four categories:silver-based brazing metal,palladium-based brazing metal,aluminum-based brazing metal,and titanium-based brazing metal.The characteristics of these four types of brazing metals are introduced,among which titanium-based brazing metal is the best choice for brazing connecting materials of titanium and titanium alloys and brazing connections with other materials,and has the characteristics of good wetting performance,good corrosion resistance and high temperature strength.This paper systematically reviews the research progress of the brazing of titanium and titanium alloys,as well as the brazing of titanium and titanium alloys with C/C composites,stainless steel,ceramics and other materials when titanium-based brazing metal is used as brazing material,focusing on the interface structure of brazed joints and the shear strength of brazed joints under the optimal brazing process,and finally looks forward to the future development direction of titanium and titanium alloy brazing technology.
