Diamond high hardness excellent physical and mechanical properties of diamond tools become that processing various materials can be hard is lack of effective tools. Tire body metal matrix for the diamond bonding (tire body bag/ability) affect the service life of diamond tool performance one of the main factors.
Because the diamonds and general metal alloy with high interface between can, cause diamond grains can't for general low melting point alloy have infiltrates, and poor bonding, traditional manufacturing technology, diamond grains only on tire body after cold gripping force produced machinery set in tire body metal matrix, and not form a firm chemical bonds "or metallurgical combination led to diamond grains work easy and tire body metal matrix separation, and greatly reduce the diamond tool life and performance level. Most impregnated diamond tool type inefficient use of, a lot of expensive diamond work loss in the crumbs off waste. LinZengDong and take the lead in using diamond surface metallization technology to give diamond surface many new features, such as good thermal conductivity, thermal stability of the physical and chemical properties, improve its original, enhance its metal or alloy solution invasive, etc.
Diamond surface metallization problems caused by the 1970 s the diamond tool manufacturing industry at home and abroad and great attention. Many people committed to sintering process of the diamond surface metallization realize, tire body materials added or diamond surface stick on the strong carbide metal powder (this diamond not before heating, did not and coating produces chemical reaction, can only belong to the diamond coating), to expect them to sintering process of chemical bond diamond with realize. Although literature has proved some metal such as tungsten (not oxidation) low temperature (800 ℃ or so) can diamond surface formation WC layer.
