Bilge Inhibitors
Abstract
A multifunctional borax-nitrite-base inhibitor has been developed for preventing corrosion damage in urinal, galley, and bilge areas of aircraft. Most of the corrosion tests were conducted in a synthetic urine consisting of more than twenty aggressive ingredients which was formulated in the laboratory. The corrosion behavior of this synthetic urine has been studied and found to be comparable to that of natural urine. A number of commercial inhibitors have been screened, and corrosion tests have been conducted with over two hundred formulations consisting of soluble, nontoxic, organic, and inorganic compounds. Several formulations have been developed which inhibit the corrosion of the most aggressive medium (urine) encountered in the bilge and related areas of aircraft. The results of corrosion-fatigue and crack-growth studies on aluminum alloys and high-strength steels confirm a reduction of nearly one-half an order of magnitude in the crack-growth rates in the presence of one of these formulations.
