Metal-coated Diamonds, Nickel-plated, Titanium-plated, and Copper-plated Diamonds, 25/30 - 325/400

Superhard material coating (electroplating, composite plating, functional plating) products

1. Electroplated products

Nickel or copper plating on the surface of single-crystal diamond, crushed material or CBN, with a weight gain of 30% or 56%. Nickel plating can improve the mechanical holding force of diamond, slow down thermal shock and increase the service life of products, which is suitable for resin-bonded products. Copper plating can improve the mechanical holding force of diamond and CBN, slow down thermal shock and increase the service life of products. It has a good dry grinding effect and is suitable for resin and bronze-bonded products.

2. Electroless plated products

Electroless nickel plating on the surface of single-crystal diamond, crushed material or CBN with a weight gain of 56% or 30%. The coating has a non-crystalline cellular structure and is hard and brittle. Compared with electroplated nickel products, it has higher processing accuracy and better mechanical holding force, and is especially suitable for resin-bonded products.

3. Composite plated products

Chemical nickel plating plus electroplating nickel on the diamond surface, with a weight gain of 30%. The products have the advantages of less adhesion, concentrated particle size, excellent magnetism and strong corrosion resistance, and are well applied in diamond wire saws, especially in silicon wafer cutting wires.

4. Magnetron sputtering coated products

Using advanced, environmentally friendly and efficient vacuum coating technology, coatings of single metals, alloys, non-metals, etc. are achieved on the diamond surface. The bonding force between the diamond and the coating is strong. The products are widely used in metal-bonded, resin-bonded, ceramic-bonded products and advanced thermal conductive composite materials.

Metal bond   Recommended coatings: titanium, tungsten, molybdenum, chromium, zirconium...

Resin bond   Recommended coatings: iron-nickel alloy, nickel, copper, copper-tin alloy, aluminum...
