Industrial Synthetic Diamond Mesh & Micron Powder By 100% Cu Coated

Red 100% Cu Coated Synthetic Diamond Powder 50/60-325/400 Mesh

Description:

Diamond is a simple crystal composed of carbon element formed under high pressure and high temperature conditions in the deep parts of the earth. Diamond is a colorless octahedral crystal whose composition is pure carbon, which is linked by carbon atoms with four-valent bonds. It is the hardest substance known to exist naturally. Since the CC bond in diamond is very strong, all valence electrons participate in the formation of covalent bonds, and there are no free electrons, so the hardness of diamond is very large, the melting point is 6900 degrees Fahrenheit, and the ignition point of diamond in pure oxygen is 720~800℃. It is 850~1000℃ in the air, and it is not conductive.

Plating products are mainly divided into electroplating and electroless plating. A layer of metal is plated on the diamond surface to improve its holding power, slow down the thermal shock, protect the diamond from oxidation and graphitization, and prolong the service life of the product. Generally, three chemical elements, nickel (Ni), titanium (Ti), and copper (Cu), are plated. Coated diamonds can be divided into two categories according to their appearance: Ordinary shape: The surface of the coated diamonds is smooth. Technical crystal burr shape: the appearance looks like a needle punch, most of the burrs are concentrated on the edge, and the coating crystal is relatively fine.

Coated Diamond Series:
Grade HID Ni Coated Diamond
Description: Coated diamond is divided into electrolytic and chemical plating, it includes Ni coating, Cu coating, Ti coating, Cr coating etc. Coated diamond effectively increase holding force between diamond and bonding, reduce thermal shock, protect diamond against oxidation and graphite, lengthen product lifetime.

Application: Electroplating Nickel products mainly used in resin bond products with dry and wet abrasives, effectively improve the holding force with good thermal stable ability, avoid carbonization in high speed cutting. Chemistry plating Nickel products mainly used in resin bond products with dry and wet abrasives, no external current conditions, and deposited metal on diamond surface by process of self-catalytic redox reactions, form the thickness and density of nickel-plated.

Grade HID Cu Coated Diamond
Description: Recommend for resin bond tools. Able to effectively enhance the tools life by improving the mechanical retention of diamonds and reducing heat damage.

Characteristics:
Effectively enhance the tools life by improving the mechanical retention of diamonds and reducing heat damage.

Grade HID Ti Coated Diamond

The coating greatly enhances the mechanical attachment of diamond to the bond matrix through the strong metallurgical adhesion between Ti and the matrix. It also protects diamond from oxidation or metal erosion which causes graphitization of the diamond, therefore, improves the application features of diamond tools.

Grade HID Si Coated Diamond
Silicon coating strengthens the retention between bond and diamond, improves the thermal stability, wear resistance and helps better conduct the heat. It also helps to avoid the corrosion from Fe, thus it protects the diamond, prolongs the tools' life and raises the sintering temperature.

Grade HID W Coated Diamond
W reacts with diamond particles and generates WC, which is with good thermal stability and wear resistance. The coating improves the bond retention and enhances the diamond toughness, its alloy coating layer improves the thermal conductivity, which can prolong tool life.

Grade HID Co Coated Diamond
Cobalt coating could improve the retention of diamond and bond. In addition, the sintering temperature could be raised because the coating can protect diamond from oxidation and corrosion. It also enhences the hardness and abrasive resistence of coated diamond.

Grade HID Cr Coated Diamond
Chromium enjoys nice wettability and affinity on diamond. It forms a layer of chromium-carbide between diamond and bond during coating and sintering, thus the coating improves the retention between diamond and bond. It also increases the hardness and abrasive resistance of coated diamond.

Application Field:
- Plating nickel products: mainly used for dry and wet grinding products of resin bond, which can effectively improve the holding force, have good heat dissipation characteristics, and prevent carbonization in high-speed cutting. Since nickel-plated diamonds are mostly used in resin bond products, burr-shaped nickel-plated diamonds combine better with resin and have better holding power. The service life of diamond products is longer than that of ordinary shapes.
- Electroless nickel plating products: mainly used for dry and wet grinding products of resin bond. Under the condition of no applied current, metal is deposited on the surface of diamond through redox reaction in the autocatalytic process, thereby forming a uniform thickness and dense nickel plating layer.
Electroplating can provide plating products with different weight gain ratios according to customer requirements; the available particle size range of electroless plating: 5μm-60μm; undertake processing business with supplied materials.
- Copper coated diamond abrasive is mainly used to manufacture resin bonded dry grinding wheels.
