Abstract
The use of a hard thin film is advanced by a recent automotive field. However, adhesion strength of a hard thin film is related directly at the product-life cycle. Adhesion was evaluated from the analysis of the destruction phenomenon on the interface between film with the machine of Nano-indentar hardness examination instrument. As a result, it was able to be confirmed that SEM in the film section was observed, and the destruction of the interface by the minimum pushing examination related to adhesion.
