| titleOfInvention | A fixture and method for a small-diameter diamond-coated wire drawing die without threading |
| abstract | The invention discloses a fixture for a small-diameter diamond coating wire drawing die without threading, a preparation method for the small-diameter diamond coating, and a metal wire. Wherein, the clamp includes a first base body and a second base body in sequence from top to bottom along the height direction of the clamp. This case is based on the hot wire chemical vapor deposition method. Through the special copper fixture and the "double-layer orthogonal" hot wire arrangement method, without the hot wire perforation, the surface of the inner hole of the small-diameter cemented carbide wire drawing die is realized. Especially in the sizing zone and compression zone, single-layer micro (nano), micro/nano double-layer composite or micro/nano multi-layer composite diamond coating with uniform thickness and quality and excellent wear resistance is deposited, which greatly improves the performance of cemented carbide. The service life and reliability of the wire drawing die break through the bottleneck that the traditional hot wire perforation process is difficult to apply to the preparation of small diameter diamond coating wire drawing die, which not only ensures the uniformity of the diamond coating on the inner hole surface, but also improves the growth efficiency of the diamond coating . |
