Majority of elemental metal or alloy which is difficult to effectively wetting and bonding

However, diamond is non-metallic material, which metal (or alloy) between strength, hardness, elastic modulus, and other aspects of the structure there is a big difference, especially the interfacial energy between the two so high that the vast most  polycrystalline diamond  metal or alloy which is difficult to effectively wetting and adhesion of diamond particles, the bonding is weak, limiting its scope of application. Therefore, the study of diamond and bond issues interfacial  Diamond blade  the metal and composite mechanism has a special significance. Given the current  abrasive wheels  polycrystalline diamond composite research status and problems to Hunan Provincial Natural Science Fund Project "polycrystalline diamond composite interface and composite Mechanism" (Project No. 00JJY2044) relying on the guidance of instructors and launched on the basis of previous work of this thesis.
