摘要
This paper describes the development and calibration of an original test apparatus to study the effect of frictional heating on lubricant effectiveness. The configuration used the Seebeck effect between a stainless steel ball and a disk of tool steel. Good agreement was found between the average temperature rise indicated by the thermoelectric voltage and Archard's models. Surface temperature rises approaching 200-degrees-C were obtained in lubricated contact and an upper bound temperature of 830-degrees-C was found in dry contact. The likely effect of track heating was assessed by analysis and, for this configuration, was found to be negligible. A slight lag was found between a local increase of friction due to the passage of an asperity and the thermal response.
