Abstract:The titanium film was coated on the surface of diamond crystal in order to improve the chemical properties of diamond and the effect of titanium coating on the property of diamond was discussed. The anti-impacting strength, the oxidization process and the soakage property between vitrified bond and diamond were investigated. It is found that, when the titanium film is coated on the surface of diamond crystal, the soakage angle between vitrified bond and diamond decreases from 39.5˚ to 34.5˚ at 993 K, and the oxidization degree on the surface of diamonds is lowered greatly.
Key words: diamond; titanium coating; soakage property
