CVD Drawing Dies
The nano-diamond composite coating drawing die is created using cemented carbide (WC-Co) as a base and employing chemical vapor deposition (CVD) to apply micron-level and nano-level diamond composite coating on the mold’s inner hole surface. Subsequent to precisely grinding and polishing the coating, a brand-new mold is obtained. The micro-nano composite coating on the surface of the inner hole possesses not only the strong adhesion and good wear resistance of the micro-diamond coating, but also the advantages of high surface finish, low friction coefficient, and facile grinding and polishing of the nano-diamond coating.
- Targeted pretreatment process: the coating is tightly bonded to the substrate.
- Bottom micron diamond coating: excellent wear resistance.
- Surface nanoscale diamond coating: excellent surface finish and low coefficient of friction.
- Computer simulation to optimize the pass design: make the wire stress uniform.
