Excerpt: ...acceleration action produced by rust accumulation, and if a barrier can be interposed so that a rust spot will spread out rather than become deeper, there will be a minimizing of the damaging action. The writer believes that slag and other non-conductive impurities frequently found in iron, under certain conditions, constitute such barrier. A study of the influence, of impurities must recognize, not only those which are alloyed with the iron and the metallographic relationship of the same, but those impurities which exist as included non-metallic compounds. Mr. Gaines: Do you mean to suggest that a half percent of silicon in wrought iron would render it more durable? Prof. Burgess: In all probability silicon as an alloy with the iron has a decidedly different influence on the corrosion than has silicon in the form of included slag. Silicon in the former condition appears to be disadvantageous, while in the latter there may be some advantage. Xa: Electrochemistry, and Ve: Paints, of the VIII International Congress of Applied Chemistry, in New York City, September u, 1912. Dr, -W, H. Walker in the Chair. A METHOD FOR TESTING THE MUTUAL CORROSIVE EFFECT OF METALS. By Hugo H. Hanson And Warren K. Lewis. It is being widely recognized that the acid test, as a measure of the resistance of iron and steel to corrosion under normal conditions, is unreliable and deceptive. Whipple & Whipple emphasize this in their paper. A trustworthy method of determining this resistance is highly desirable. A test for determining the relative values of paint films as protective coatings for iron and steel, devised by one of the authors (Walker and Lewis, Jour. Ind. Eng. Chem., 1, n (1909)), developed by the late Mr. M. T. Jones, and used recently by Mr. W. C. Slade...
