It is shown that high penetration of the CPCs can lead to the reduction of the riveted joints fatigue life.

Introduction For thin walled aircraft structures the problem of the corrosion is crucial, therefore the efforts are aimed both for development of the new materials and methods for the protection against corrosion. Corrosion Preventive Compounds (CPCs) also known as Corrosion Inhibiting Compounds (CIC), Water Displacing Corrosion Preventative Compounds (WDCPs) are widely used in contemporary civil aviation as an additional method for the aircraft protection against corrosion. CPCs are classified as Water Displacing Soft Film, 1.
