In the press forming, dry press forming would be required for environmental problem. In this study, a diamond-like-carbon (DLC) for achieving the dry press forming was applied to the surface of blanks. Then, the effect of the deep-drawability of A5052 aluminum alloy sheet with DLC-coating was investigated due to improve the formability in dry press forming. The deep-drawing experiments were carried out at the elevated temperature improve the formability of A5052 aluminum alloy sheet. The deep-drawability with DLC-coating was examined by deep-drawing test and friction test. As the result, dry press forming of the aluminum alloys without metalic adhesion was achieved by DLC-coating. In addition, it is confirmed that the formability of A5052 aluminum alloys sheet due to lower friction coefficient between blank and the die in the case of DLC-coating is improved in comparison with lubricating oil.
