Ice friction, wear features and their dependence on sliding velocity and temperature

Abstract

Friction processes for ice samples sliding on steel have been determined by examining wear and debris morphology with low-temperature scanning electron microscopy and relating the processes to the velocity and temperature of formation. Friction experiments were carried out over a temperature range of -27 to -0.5°C and velocity range of 0.008-0.37 ms-1. Data were used to develop a friction map. Low friction 0.15) at low temperature (-24.5°C)-low velocity (0.03 ms-1) results from insufficient lubrication at the sliding interface, leading to plastic deformation. Diagnostic morphologies of plastic deformation include scuffing features on the wear surface and the accumulation of sheets of unconsolidated debris on the trailing edge of the wear surface.
