study of the character, causes, and prevention of the rusting of iron and steel, though of comparatively recent date, has already inspired a vast literature. Evans (5), Friend (9), Pollitt (14), and Speller (18) are the authors of handbooks on this subject.Certain metals-for example, aluminum, copper, and leadare protected from more than a very superficial corrosion in air or in water by the development of a tightly adhering, impervious film of oxide, basic sulfate, or basic carbonate (6). A similar protective film of oxide is formed on iron that has been rendered passive by immersion in chromate solution or in concentrated nitric acid ( 22). Evans has also shown that even on exposure to air a film of iron oxide forms on iron which gives temporary protection against rusting (If),The destruction of iron and steel by rust is usually more rapid in salt solutions (refrigerator brines, sea water, etc.) than in ordinary fresh water. The usual inhibitor employed in refrigerator brines is sodium or potassium chromate (20),
well recognized. To some extent, they replace sugar in saturated solution. Therefore, Steffen molasses is produced at a purity lower than non-Steffen.But, because they increase viscosity and, in the case of raffinose, interfere with crystal development (S), the carbohydrate nonsucrose components decrease
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
