Coating drawing die

Nano-diamond composite coating drawing die, based on carbide (WC-Co) as the substrate, the use of chemical vapor deposition (CVD) in the mold hole surface of the micron level and nano-level diamond composite coating, and The coating is subjected to precision grinding and polishing to obtain a new mold. Micro-nano composite coating on the surface of the hole, both micron-grade diamond coating adhesion, good wear resistance characteristics, but also nano-diamond coating surface finish, the friction coefficient is small and easy grinding and polishing advantages.  Pretreatment process: the coating and the substrate closely with the underlying micron-scale diamond coating: excellent wear resistance of the surface layer of nano-diamond coating: excellent surface finish and low coefficient of friction computer simulation optimization hole design: So that the wire force evenly
