PULSE POLARIZER STUDIES OF CORROSION PREVENTIVE OILS.

Abstract

The purpose of the study was to find a method which would require less time and be more accurate than corrosion tests currently used in military specifications. Various electrical methods are discussed as to their ability to evaluated effectively corrosion preventive oils. The Pulse Polarizer method was applied to iron specimens coated with corrosion preventive oils and immersed in a 1N KCl solution. The efficiency of the oil was based on its ability to restore a breakdown of the film, caused by pulse discharge, to its original noncorrosive equilibrium potential. A good correlation was obtained when the potential data of MIL-L-3150 and MIL-L-21260, Grade 1 oils were compared to their protective ability in the JAN-H-792 Humidity Cabinet Test. The results indicate that the Pulse Polarizer technique can be used to determine the protective ability of the two types of corrosion preventive oils studied. (Author)
