Observations on gold-palladium-silver and gold-palladium alloys
The Journal of Prosthetic Dentistry, 1980Properties, heat treatment response, structure, and composition of three high-fusing crown and fixed partial denture alloys were studied. Except for elongation, the properties of two gold-palladium-silver based materials were compared to those of a gold-palladium alloy.

1991
The bulk diffusion of gold into rhodium in thin films has been studied by [13]. Do was found to be 4.2 x 10−11 cm2/s and Q=0.93±0.28 eV. The bulk diffusion coefficients are plotted against reciprocal temperature in Fig. 173. The authors point out that these values of Q and Do are lower than would be expected for lattice diffusion in face-centred cubic ...

Electropolishing of gold and gold-rich alloys
Micron (1969), 1977Abstract The use of a mixture of sulphuric and hydrochloric acid is proposed for electropolishing gold and gold-rich alloys for study by electron microscopy. The results obtained using the proposed electrolyte are illustrated using an ordered Au4Zn specimen in which different phases of Au3Zn(H) and Au3+Zn can be recognized.

Reflectivity of gold and gold-silver alloys
Economic Geology, 1967Reflectivities of gold-silver alloys between 500 and 1,000 fine are given for six wavelengths and the curve showing spectral dispersion of reflectivity of pure gold is compared with those produced by other workers. The polishing technique is shown to have a profound effect on the optical properties, with a range of up to 15 percent in reflectivity ...
