The result shows that the temperature has important effect on the friction properties. The friction coefficient decreased slowly and became not smooth with the temperature rising. The wear rates have great increase with the temperature rising for the cumulative friction heat.

Does increased temperature increase friction?

As the temperature increases, the coefficient of friction has a greater variation. Except from the experimental results carried out at 100 ºC, the general tendency of the coefficient of friction is to decrease as the contact pressure increases.

What is the relation between temperature and coefficient of friction?

The coefficient of friction is found to be strongly dependent on temperature and decreases continuously from 0.78 to 0.46 between 24 °C and 450 °C. 4. The reduction in coefficient of friction is found to be commensurate with the progressive formation of a 'glaze-layer'.
