摘要

At elevated temperatures Nickel Alloys have the ability of forming a 'glaze' layer. If the test conditions are favourable, this layer can protect components from subsequent wear and fretting damage. This phenomenon has been previously shown by several researching bodies. Unfavourable conditions, on the other hand, can either delay or prevent its formation, rendering a component susceptible to further damage. This study investigates the effect that various test parameters have on the formation of these glaze layers, and how this may impact the fretting fatigue life. Parameters investigated include normal load and cycle frequency. Tests were carried out at two temperatures: 20℃ was used as the control group, and 680℃ as the experimental 'glaze' group. Experimental results are provided, and explained in terms of wear rate and frictional effect.
