Electrodeposition and properties of bismuth alloys with low-melting metals

The electrodeposition of bismuth alloys with indium, lead and cadmium from trilonate baths is investigated. X-ray diffraction and scanning electron microscopy are used to determine the structure of the prepared alloys deposited under various electrolysis conditions. The electrocrystallization conditions of two-phase alloys-mechanical mixtures, are determined. The electrochemical alloying of bismuth coatings with low-melting metals is conducive to refining the grain structure, smoothing the surface relief, and increasing their acidic corrosion resistance.
