Herbert Henry Uhlig (3 March 1907 – 3 July 1993) was an American physical chemist who studied corrosion.
This was interrupted by World War II, during which time he joined the staff of the Research Laboratory at the General Electric Company in Schenectady, New York, to study metal corrosion on aircraft and other military equipment.
In the area of passivity, Uhlig showed that the chemisorbed oxide layer is too thin to serve as an atomic diffusion barrier in electrochemical corrosion, which was the commonly held view at the time and, rather, functions to decrease the rate of the electron transfer process (oxidation-reduction reaction).
He also concluded that the minimum ratio of metals corresponding to passivity in binary alloys tends to be retained in higher-order ternary and quaternary systems.
Canadian metallurgical engineer R. Winston Revie was the editor for subsequent editions of each book.
