    Abstract

    Fretting wear, produced by the twisting motion of a flat steel specimen against a fixed 12.7-mm steel ball, has been investigated in the limited microslip region ranging from 0.05 to 5.0 μm. The construction of the test rig and the type of fretting wear associated with this particular specimen configuration and motion are discussed. This discussion is exemplified by data obtained either with SAE 52100 steel or Hastelloy B alloy ball specimens in combination with SAE 1018 steel flat specimens. The first indication of metal oxidation normally associated with the onset of fretting occurred at a slip amplitude of about 0.075 μm. Severe damage was noted at 2.5 μm.
