Coated diamond is made of coating of a specific thickness of metal layer on the diamond surface. The metal coating can improve the combination ability of diamond abrasive and binder, enhance the control force of abrasive, cover up the defects of abrasive itself, improve the strength, thermal stability and chemical corrosion of abrasive. At the same time, the metal coating can isolate the air and improve heat dissipation, then protecting the diamond abrasive from oxidization and graphitization, prolonging the service life of the products.
Synthesis and Classification
Chemical plating and electroplating are the two major ways to synthesize coated diamond. According to the appearance, coated diamond can be roughly divided into two types: ordinary shape (the surface of coated diamond is smooth) and burr shape (the diamond surface looks like needling from the outside, most of the burrs are clustered in the edge and the crystallization of coating is relatively delicate). In addition, the most common classification way is according to the coating type, coated diamond can be mainly divided into nickel coated diamond, titanium coated diamond, copper coated diamond and chrome coated diamond.
- Various diamond can be coated by our Alfa Chemistry.
- Our mature plating process ensures that the diamond coating is compact and uniform, while also allowing precise control of coating thickness and metal weight gain.
- Our unique surface purification pretreatment process makes the firm adhesion between diamond and coating.
- Our rich experience of dispersion and surface treatment of nano-sized powder, ensure the products will not appear adhesion phenomenon.
