Blevins, R. D.

The results of a series of measurements made on the fretting wear of heat exchanger tubes and support plates at room temperature in a nitrogen/air atmosphere are presented. The fretting wear is shown to be a function of the amplitude and frequency of tube vibration as well as the gap between the tube and the support plate and the mean load supported by the tube. Conceptual and empirical models are developed for the fretting wear of heat exchanger tubes. The models are based on the experimental data on the concept that fretting wear is the result of relative motion between the tube and the support plate.
