Abstract

In this paper, the application of TZM alloy and the development on brazing technology of TZM alloy is described. Combined with the practical engineering applications, the special brazing filler metal for TZM alloy which can serve at 1 300 ℃ is developed. The wettability of the brazing filler metal(BFM) over the surface of TZM alloy is tested, a reference wetting area is introduced to determine the vacuum wettability of the BFM and the effect of Cr on the properties of BFM is discussed. The results show that the corresponding relationship between shear strength and composition is that with the addition of Cr, the shear strength of the joint first becomes larger and then becomes smaller, which can provide an important reference for practical engineering applications. It is found that when the content of Cr in the BFM is 3 wt.%, the wettability of the BFM is the best and the shear strength of the joint is the highest at 135 MPa.
