Abstract
The relationship between current density and the properties of gold-tin alloy deposit from pyrophosphate solution containing potassium dicyanoaurate (I) and stannous pyrophosphate has been studied. The composition of the alloy depended on current density and affected hardness. The increase in current density increased the tin content of the alloy, but current density was independent of orientation, which shows the crystal form, and had no effect on an amount of wear. However, SEM photographs showed that current density has marked effect on the condition of the deposited alloy.
