The Measurement of Surface Temperature in Dry or Lubricated Sliding

Abstract

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°C were obtained in lubricated contact and an upper bound temperature of 830°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.

Thermographic Inspection at the Interface of Dry Sliding Surfaces

“…However, measuring the interface temperature of a friction pair is a difficult task. Several methods have been reported (Dinc et al,1993), but infrared measurements seem to be the most effective (Anon, 1995, Cuccurullo et al, 2010. Some conclusions are well established.…”

Raman characterization of Ti–6Al–4V oxides and thermal history after kinetic friction

“…As a consequence, the efforts and the extreme surface stresses can be reduced by optimizing the mechanical parameters during friction for each material. Nevertheless, temperature is still one of those parameters currently difficult to control and measure during friction [4][5][6] because of extremely localized areas of temperature rises. An additional element that complicates the measurement of the overheating at the interface is the non-uniformity of temperature fields.…”

A Model for the Estimation of Brake Interface Temperature

“…• Analysis of results and validation of the mathematical model. different temperature non-contact measurement methods [13], such as optical and infrared methods, and contact type methods, as well as temperature measurement using thermo-couples or different temperature-sensitive materials. According to [14], the most effective way to determine the temperature on the contact surface of the disc and brake pads in the vehicle during braking is by applying thermocouples.…”
