The gold solder, gold alloy interface.
With soldering the physical properties of the basis metal must be maintained and a minimum of molten metal is used. An examination of joints in 17 gauge platinized gold wire is made with 18 k gold solder following quenching immediately after flow and cooling in air; there is a widening of grain boundaries and intergranulation penetration in the latter method. A comparison with the cast gold joint is made. Some inclusions were noted.
