Abstract
To join titanium and titanium alloy for a crown and bridge, soldering with titanium solder is desirable. Therefore, composition of titanium solder was analyzed and tensile soldering strength was measured. Wave dispersive electron probe X-ray microanalyzer was used for an analysis of the composition. Pure titanium bars (Type 3) were prepared and soldered in an argon gas atmosphere using an infrared soldering apparatus.
As a result, it appeared that the composition of commercial titanium solder was Ti, Ni and Cu and the structure of the layered solder was Ti and Ni-Cu alloy. The composition of Ti, Ni and Cu was 50〜67 wt%, 17〜30 wt% and 16〜20 wt%. The tensile strength of the soldered joint was 392〜516 MPa.
