STUDY OF PARAMETERS WHICH AFFECT CORROSION BETWEEN SOLID FILM LUBRICANTS AND AIRCRAFT ALLOYS

This paper summarizes the findings of a program demonstrating how parameters such as humidity, surface pretreatment, inhibitors, SO2/salt ratio, environment, etc., affect corrosion between solid film lubricants and various aircraft alloys. It was found that burnishing the surface of a solid film lubricant causes rapid loss of corrosion protection. The reason for this could be that the MoS2 particles are pressed closer together and become more of the conductor. If this is true, it would mean that a lubricant does not have to contain graphite to cause galvanic corrosion when involved in a dissimilar metal couple. Pretreatments were found to have less effect than expected on corrosion prevention. Humidity was found to have no effect on wear life or corrosion rate.
