THE ELECTRODEPOSITION OF SINGLE CRYSTAL GOLD-ALUMINUM OXIDE ALLOYS.

Abstract

Singel crystals of gold and gold-aluminum oxide were obtained by electrodeposition on a single crystal silver substrate according to the method developed by Kuhlmann-Wilsdorf. An annalysis of the factors determining the growth of the single crystals from the electrolyte indicates that the temperature and rate of growth of the deposit are the controlling factors rather than the purity or salt content of the bath itself. It was found that the films containing Al2O3 are much more stable to recrystallization than those of pure gold. Techniques for the preparation of the transmission specimens involving minimum coldworking were developed and the films examined in the electron microscope. (Author)
