Study of thermal interfacial resistance between TC11/glass lubrication/K403 joint

The heat transfer between the workpiece/glass lubricant/tool has an effect on the accuracy of the workpiece and tool-life during forging process. Consequently, accurate thermal interfacial resistance (TIR) data are needed for a heat management of the forging system. A test facility and relevant procedure are developed to measure the thermal interfacial resistance across the interface, employing a steady-state method. The effects of the average interfacial temperature, contact pressure and the thickness of the glass lubricant are evaluated. Some experimental results on the temperature dependence of the thermal conductivity of glass lubricant are presented.
