The initial process on the gold cathode is the epitaxial growth of a layer up to 3 µm thick with a smoothed surface and a considerably later growth of grain boundaries. Gradually, on the protruding parts of deposit, the growth of dendrites starts. The dendrites are the major form of gold deposits. Typical gold dendrites are two-dimensional 2D112 and 2D112n110 and three-dimensional 3D100. Upon supplying air into the atmosphere above the melt at high current densities at the initial period there appears a powder comprising particles of a rounded twisted shape. Probable mechanisms leading to the formation of the iroundedi powder are discussed. Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Semerikova, O. L.; Molchanova, N.
