Izgaryshev, Nikolai Alekseevich
Born Nov. 4 (16), 1884, in Moscow; died there Mar. 21, 1956. Soviet electro-chemist. Corresponding member of the Academy of Sciences of the USSR (1939). Member of the CPSU from 1945.
Izgaryshev graduated from Moscow University in 1908. He taught in various Moscow institutes, becoming a professor in 1917. Izgaryshev discovered the phenomenon of the passivity of certain metals in nonaqueous electrolytes and showed that other compounds besides oxides may be passivators. A series of his works were devoted to the theory of galvanic elements and electrode processes. Between 1938 and 1951 he investigated the reaction of ferrous metals with vapors of salts of other metals. These reactions are used in chromizing and other thermochemi-cal methods of protecting metals and alloys from corrosion. Izgaryshev was awarded the State Prize of the USSR in 1949.
