| Outline of Final Research Achievements |
To evaluate adhesion quality of diamond-like carbon (DLC) film for the life prediction of the die for glass press molding, laser spallation technique, thermal shock test and indentation test were carried out. Cyclic thermal shock test was useful to evaluate the adhesion quality and surface damage of the DLC film at high temperature, and was possible to estimate the influence of the intermediate layer structure on the adhesion quality. In the indentation test, the adhesion quality of the DLC film at high temperature up to 300℃ was decreased with temperature increasing. The cyclic number to crack initiation for the sample in 300℃ was smaller than that in room temperature.
