Abstract : When an object slides over an ice surface the kinetic frictional force does not behave according to either the lubrification, boundary or solid-solid types of classical friction.
In the attempt to explain frictional dependence on the temperature, the normal force and the relative them conductivities of the contacting materials , investigators have proposed the existence of one of three different phases of H p lubricant-liqid, vapor, and surface layer phase. The latter (referred to as the quasi-liquid or anofidlous layer) has been postulated to possess structural and electrical properties that are significantly different from those of ice or water and a greater rotational freedom has been ascribed to its molecules than to the H p molecules in the bulk beneath the a m l o u s layer.
The kinetic frictional force experienced by an ice surface has been measured for single crystals as well as for plycrystals for a wide range of physical. conditions, for relative velocities of nine orders of magnitude, for temperatures down to -30°C, for granite, glass,.brass, steel, ice and other contacting materials.
