Abstract — Some peculiarities of the Al–1Sn alloy corrosion in sodium sulfate solution were investigated by applying video-observation in-situ. As a result of the free corrosion the inclusions of almost pure tin were revealed and identified with the use of a scanning electron microscope. The hydrogen evolution occurs just at the inclusions1.

Abstract — 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.
