Bonding Strength of Titanium Alloy Joints Brazed with Low-Melting-Temperature Zirconium Based Filler Metals

The wettability, microstructures, and bonding strength of infrared brazing Ti-15-3 and Ti50Ni50 shape memory alloy using 72Ag-28Cu (wt.%) and 68.8Ag-26.7Cu-4.5Ti (wt.%) filler metals have been investigated. Only Ticusil® active braze readily wets both Ti50Ni50 and Ti-15-3 substrates. Wetting of eutectic 72Ag-28Cu melt on Ti50Ni50 base metal is greatly ameliorated by adding 4.5 wt.% Ti into the alloy. The brazed Ti-15-3/BAg-8/Ti50Ni50 joint consists of Cu-Ti intermetallics in the Ag-rich matrix. The formation of interfacial Cu(Ti,V) and (CuxNi1−x)2Ti intermetallics next to Ti-15-3 and Ti50Ni50 substrates, respectively, is attributed to the wetting of both substrates. The brazed Ti-15-3/Ticusil®/Ti50Ni50 joint shows a vigorous reaction, which results in the formation of a large amount of Ti2Ni intermetallics in the joint. The maximum joint strengths using BAg-8 and Ticusil® filler metals are 197 MPa and 230 MPa, respectively.

Gradient Coating

To improve bonding strength between titanium alloy and coating and to eliminate thermal stress during laser cladding, a gradient coating materials is designed. And the gradient coating with different contents of multiple rare earth deoxide was produced by wide band laser cladding technique. The experimental results indicate that when addition of Sm2O3 is fixed to 0.3wt.%, as addition of Y2O3 increases, the microstructure of bioceramic is different. When addition of Y2O3 reaches 0.4wt.%, the amount of Ca-P based bioactive phases such as HA, α-TCP as well as β-TCP becomes biggest. After soaking the coating with 0.3wt.% Sm2O3 and 0.4wt.% Y2O3 in SBF for 14 days, a large amount of Ca-P white spherical particles can be observed on coating, which demonstrates the bioceramic coating is of best bioactivity.
