Advantages of CVD diamond:
High transmission,Good Thermal stability and chemical stability.. It is the best replacement of natural diamond .
CVD diamond has low surface roughness and good cutting edge compared to PCD tools.
CVD diamond has higher wear resistance than PCD and other diamond materials.
The thermal conductivity of CVD diamond is 50% higher than PCD.
Good hardness and long life exceed HPHT and natural diamond.
Applications of CVD diamond:
CVD diamond is used for semi-finishing, finishing, super finishing and continuous cutting of ultra precision cutting tools.
For Manufacturing a scalpel, ultra-thin medical tools such as biological section;
for processing mirror and rocket navigation gyroscope, computer hard disk substrate, electron accelerator ultra-precision mirror parts, etc
In addition, the CVD diamond is also used for other high-tech applications (such as diamond dresser, wire drawing die, electronics ,optical window, heat spreader and gem stone industry, etc)
Manufacturing a scalpel, ultra-thin medical tools such as biological section;
Note:1, diamond has the brittleness, it is easy to produce cracks or debris after a certain impact, it is important to prevent the impact in the process of installation and use2, When the air's temperature over 850 ℃,the surface of diamond will have acarbonation reaction3, in normal temperature environment is not suitable for cutting ferrous metals (iron, cobalt, nickel, manganese, chromium), except a protective gas cutting environment.
-CVD Character:- Melting point(℃):3800-HV HARDNESS(MPa):80000-Young modulus(KN/mm2):1050-The thermal expansion coefficient(10-6/K):1.3-Thermal conductivity(W/m.K):800--1800
