Compound connection mechanism of Al(2)O(3) ceramic and TC4 Ti alloy with different joining modes

In this paper, laser welding-brazing of TC4 Titanium (Ti) alloy and Al(2)O(3) ceramic dissimilar material was carried. The results showed that the Ti alloy and Al(2)O(3) were joined by melting filler metal when the laser was concentrated in the Ti alloy side of the joint. The joint with one fusion w...

description In this paper, laser welding-brazing of TC4 Titanium (Ti) alloy and Al(2)O(3) ceramic dissimilar material was carried. The results showed that the Ti alloy and Al(2)O(3) were joined by melting filler metal when the laser was concentrated in the Ti alloy side of the joint. The joint with one fusion weld and one brazed weld separated by remaining unmelted Ti alloy. Laser beam offset the Ti alloy 1.5 mm, Ti alloy would not be completely melted in joint. Through heat conduction, the filler metal melted occurred at the Ti-ceramic interface. A brazed weld was formed at the Ti-ceramic interface with the main microstructure of β-CuZn + Ti(2)Zn(3), β-CuZn and Al(2)Cu + β-CuZn. The joint fractured at the brazed weld with the maximum tensile strength of 169 MPa.
