Fretting fatigue and fretting corrosion are common types of tribological damage caused by oscillating contacts. The level of surface temperature generated by friction in the contact zone under these conditions and its effect on the fretting process will be studied. Experimental temperature measurements obtained by infrared microscopy will be combined with tribological fretting data and with relevant heat transfer analyses to formulate a model for the role of temperature in fretting damage. Effects of sliding distance and velocity as well as of oxide films will be included. The study will result in a better understanding of the fretting process and could lead to better guidelines for materials selection and development for fretting conditions.

微动疲劳和微动腐蚀是由振荡接触引起的摩擦损伤的常见类型。将研究在这些条件下接触区摩擦产生的表面温度水平及其对微动过程的影响。通过红外显微镜获得的实验温度测量结果将与摩擦学微动数据和相关传热分析相结合，以制定温度在微动损伤中的作用模型。将包括滑动距离和速度以及氧化膜的影响。该研究将有助于更好地理解微动过程，并可能为微动条件的材料选择和开发提供更好的指南。
