โœฆ Synopsis

Research in the Quality and Integrity Design Engineering Center of the University of Utah was conducted to determine the relative ลฝ . importance of wear and corrosion oxidation failure mechanisms on the fretting fatigue behavior of 8090-T7 and 7075-T7351 aluminum ลฝ . alloy specimens. Specimens were tested either in laboratory air or in the vacuum chamber of a scanning electron microscope SEM . The fretting fatigue process in the SEM vacuum was assumed to be relatively more wear and less corrosion dependent than the process in air. Under the test conditions it was found that the wear mechanism dominates for the 8090 alloy, but that the corrosion mechanism appears to dominate for the 7075 alloy.

This paper proposes a modification on both the Smith-Watson-Topper and the Morrow parameters concerning the prediction on fretting fatigue life, in order to take into account the wear damage. It is proposed that, besides the principal stresses involved in fretting contact (axial, normal and tangenti

It is well known that the fatigue limit in air disappears in a corrosive environment. This is often because corrosion pits initiate and grow in the early stage of corrosion fatigue process, and a final failure of specimen is brought by crack initiation and propagation from the grown pits, even if th
