HARD COATING FILM HAVING ANTI-ADHESION PROPERTY TO SOFT METAL |
| 摘要 |
The invention provides a hard coating film insusceptible to adhesion to a soft metal, the hard coating film being suitable for use as a coating on the surface of, for example, a die in contact with the soft metal. Further, the hard coating film includes a metal element containing at least two species of elements selected from the group consisting of Ti, Al, and Cr, and a non-metal element containing O (oxygen) only, or O and at least one species selected from the group consisting of C and N. A proportion accounting for the O in the total non-metal element is not less than 0.2, in atom ratio. |
