A method for calculating the anodic polarization curves of binary alloys from those of their components is presented. Heterogeneous alloys can be treated as simple galvanic couples, but homogeneous alloys are subject to a modification of Tammann's concept of surface enrichment. Potentiostatic anodic polarization curves are used to compare the calculated and experimental curves. Data are presented for the tin‐zinc, cadmium‐zinc, iron‐chromium, titanium‐chromium, and iron‐titanium systems.

“…Research on external corrosion of pipe lines has resulted in the development of good working theories which have aided in the development of remedies or means of overcoming such corrosion. Morral and Bray (28) showed that the anodiccorrosion of aluminum bronze, silicon bronze, and copper in 20% sulfuric acid solution is quite high compared with other materials: they investigated the anodic corrosion resistance of sixty-eight metals and alloys.…”

“…Tellurium-lead resists corrosion by most strong acids to a remarkable degree and v'hen attacked leaves a uniform surface unlike the pitted surface obtained when pure lead is used. The rate of solution of a lead anode containing 0.05 per cent tellurium is one tenth that of commercial lead in an electrolyte containing [15][16][17][18][19][20] per cent by rveight of sulfuric acid (91). The presence of 0.5 per cent tellurium is reported to double the life of lead in sulfuric acid plants (103).…”

SeleniumScrubber Solutions SELENIUM is widely distributed over the world's surface, but the total amount has been calculated to be equal only to that of gold or bromine. The availability of tellurium is less than half that of selenium, and both of these elements are usually classed among the rarer elements. However, they are not rare in the sense of being unavailable to commerce, since nearly 1,000,000 pounds of selenium are recovered yearly in peacetime. World production of tellurium is about 200,000 pounds yearly.Selenium and tellurium are readily available because they are concentrated in small amounts in most of the important sulfide ores of copper, silver, gold, and nickel-copper which are mined in the United States, Canada, Mexico,
