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.
► Aluminum alloys have several advantages. ► Dry press forming of aluminum alloys which never used lubricating oil is required. ► The disposal of a large amount of lubricant waste is a serious environmental issue. ► New lubricating technique that have less impact on the environment are a necessity. ► In this study, diamond-like-carbon was applied to the surface of aluminum alloys. ► The effect of the deep-drawability of A5052 aluminum alloy sheet was investigated.
