| Properties of CVD Diamond Coating Wire Drawing Dies 1. What is the CVD diamond coating wire drawing die? CVD diamond coating wire drawing die, using carbide substrate as raw material and chemical vapor deposition (CVD), was used for micro level and nano level diamond composite coating on the inner surface of the dies, and then the coating was polished and polished to obtain a new die. The inner hole surface of the die is close to the nature of natural diamond, and has the characteristics of high finish and good wear resistance. 2. Advantages of CVD diamond coating wire drawing die 1, The die replacement period is long, the production continuity is good, and the energy consumption is reduced. 2, Reduce the labor intensity of 90% workers and improve the production efficiency. 3, Improve product quality, production process line diameter without change. 3. Production process We introduce the mixture of carbon source gas and hydrogen into the vacuum chamber, and the gas is decomposed and decomposed at high temperature and below the standard atmospheric pressure, forming active carbon atoms and depositing on the substrate to grow into polycrystalline or monocrystalline diamond crystals. 4. Application of the CVD Diamond Coating Wire Drawing Dies
It is suitable for drawing all kinds of gas shielded welding wire, high carbon steel wire, medium and low carbon steel wire, stainless steel wire, copper and aluminum wire and all kinds of special-shaped pipe and wire without selecting material.
5. Properties and Characteristics of CVD Diamond Coating Wire Drawing Dies
(1) Die life, physical and chemical properties of the coating
Under normal working conditions, the drawing tonnage is more than 30 times of the carbide drawing dies;
Physical performance
(2) Die Characteristics: -Special pretreatment technology creates super strong film base bonding force and prolongs die life; -Ultra long life, greatly reducing the mode frequency; -The ultra fine nano polishing surface improves the quality of wire rod; - Improve drawing rate, achieve ultra high speed drawing and improve production efficiency; -Without special cooling, water cooling can ensure long life; -Without special lubrication, clean and lubricated medium can realize the super long service of the mould;
