From classical approximation, we can say that the frictional force is independent of the temperature of the surface.
heating of a surface will increase the K E of the molecules.this KE is due to the vibrational motion of the molecules. whereas frictional force appears due to the relative motion of the surfaces.friction adds on heat to the surface.
