Abstract

The field of chemical literature points to many applications of aluminum and its alloys as an important metal for various structural purposes. Among the many reasons for aluminum and its alloys being so unique as a metallurgical substance are its low specific gravity, high thermal and electrical conductivity, high reflectivity for radiant energy and ease of fabrication. Chemically considered, its compounds are colorless and are without harmful action upon the human system. While ordinarily quite inert, at very high temperatures or in the presence of certain chemicals, notably strong alkalies, aluminum as a strong reducing agent is used to reduce certain metals from their ores and to remove gases from molten steel. It also possesses high resistance to the corrosive action of the atmosphere and a great variety of chemical compounds. Considerable research has been conducted on the use of inhibitors which have been added to corroding media to prevent the deterioration of metals by the attacking materials. Such agents as sodium silicate, hydrogen peroxide, etc., have been used to inhibit the effect of alkaline solutions on aluminum. More recent is the practice of using organic agents for the same purpose. The present work is an investigation on aluminum to ascertain the inhibiting effect of various series of nitrogen containing organic compounds in the presence of an attacking medium.
