Hardness measurement considered the influence of the basis material hardness exerted on the surface property of a DLC film. Bi free cutting steel and Super hard alloy were selected in basis material. The rapid hardness fall took place at the time of the depth in which indentation broke through the film of Super hard alloy/DLC as a result of hardness measurement. Recorded image of indentation observation was performed in order to solve this cause. Consequently, the hollow had generated Super hard alloy/DLC. Moreover, a rapid change in the depth direction was looked at by the action graph of examination process. From the above thing, with Super hard alloy/DLC, by there being no crack, since modification was also small, energy was accumulated, when a film was broken through energy was wide opened from one point, pushing in the rapid depth direction took place, and hardness fell.
