Abstract:The preparation methods of fixed diamond，such as wire brazing, resin bonded adhesion and electroplating were summarized. The principle, model and methods of cladding on diamond were analyzed, and some methods of cladding on diamond were compared. The mechanism of composite electroplating containing the theories of adsorption, mechanics and electrochemistry was discussed. The developmental trends of the preparation of fixed diamond wire saw were proposed.
Key words: diamond; wire saw; fixed grits; cladding; composite electroplating; depositional mechanism
