The frictional experiments have been carried out on alloyed tool steel (STD11) to investigate frictional surface and its hard layer. The results obtainedare as follows;
The average hardness of frictional surface increases with the compressing force, but decreases after a specific compressing force.
It also increases with the sliding distance, but stays constant after a specific sliding distance.
The thickness of hard layer due to friction increases with the sliding distance.
