 COATING TECHNOLOGY |
| Violet Coating |
| (Al,Ti)N coating, which has excellent adhesion strength for HSS tools. |
| Succeeded in applying Miracle coating technology for carbide substrate to HSS tools. With the newly developed high adhesion technology of (Al,Ti)N coating at low substrate temperature needed for HSS coating process, Violet coating has the same level of adhesion strength as Miracle coating in addition to high film hardness and excellent oxidation resistance properties. |
 FEATURES OF VIOLET COATING |
| Violet Coating | TiN | |
| Hardness (HV) | 2,800 | 1,900 |
| Adhesion (N) | 80 | 60 |
| Oxidation Temperature (°C) | 840 | 620 |
