Title:
INVESTIGATION OF VOLATILE CORROSION INHIBITOR ADDITIVES FOR STANDARD OPERATING OILS TO IMPROVE THEIR PRESERVATIVE CHARACTERISTICS

Abstract:
Nine volatile corrosion inhibitor VCI concentrates were evaluated in eight selected base oils to determine the feasibility of utilizing a VCI concentrate to improve the preservative properties of operating lubricants. The work reasonably demonstrated the feasibility of using carefully selected concentrates to improve the preservative properties of an operating lubricant. However, unpredictable compatibility problems may prevent a practical application of this process. Three promising concentrates were found that would provide vapor phase protection comparable to that of Specification MIL-L-46002 VCI oil, and exhibited only slight sedimentation in compatibility tests with operating lubricants. Of the three, only one had the supply and logistics properties deemed to be most desirable. It was revealed that concentrates in liquid form were best suited because solubility problems were encountered with the powdered form of concentrate. The type of diluent which is part of the concentrate can also produce detrimental effects on a product when it is added to an operating oil as evidenced by drastic changes in viscosity, pour point and flash point.
