Abstrak

Active brazing of zirconia with metallic alloys is a promising method for enhancing the mechanical property of zirconia. However, the brazing process of zirconia and metallic alloys has not been studied in detail because of a limitation in selection of materials and processing conditions. Here, we successfully brazed zirconia with Ti-3Al-2.5V alloy using amorphous Zr<sub>54</sub>Ti<sub>22</sub>Ni<sub>16</sub>Cu<sub>8</sub> active filler alloy. By manipulating the brazing temperature from 800 °C to 860 °C, a highest strength of ~186 MPa was achieved at 860 °C. Reduced brittle (Zr,Ti)<sub>2</sub>(Ni,Cu) intermetallic phases from formation of island-type (Zr,Ti) matrix, ZrO<sub>2-X</sub>, TiO, and TiO<sub>2</sub> interlayer play a key role in increasing the joint strength. Our findings will be helpful in developing brazing processes for zirconia and metallic alloys.
