IN RECENT years, chafing, galling, or fretting corrosion of surfaces in contact has become a serious problem in aircraft engines concurrent with increased demands for more power and minimum weight.Deflection of parts designed for minimum weight increases the tendency of clamped or pressed surfaces to move slightly relative to each other, especially under increasing loads. This motion causes chafing, which introduces stress concentration in the affected areas.The authors describe a group of laboratory tests evaluating a limited number of methods for eliminating chafing, primarily for application to aircraft-engine development.Results indicate that chafing can be prevented by:
