100% Cu Coated 325/400 For Resin Bond Diamond Powder Grade HID R

325/400 mesh Plated Resin Bond Diamond Powder for Lapping

Description:

Plated diamond particle products are mainly divided into electro-plated diamond particles and chemical-plated diamond particles. One layer of metal is plated on the surface of diamond particles for improving holding force, reducing thermal shock, protecting the diamond surface from oxidation and graphitization so as to prolong service life of tools. Plated metals are nickel(Ni), titanium(Ti) and copper(Cu).
Plated diamond particles also can be divided into the fallowing two types according to exterior appearance of the plated diamond particles:
Normal type: plated diamond has a smooth plating surface.
Dendritic crystal-burr type: metal coated on the surface of diamond particle forms a structure of dendritic crystal,it looks like a burr,and most burrs are concentrated on the edge.The crystallization of the coated layer on the surface of diamond particle is 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:
- Nickel electroplated products: the product is mainly used to fabricate resin-bonded tools for dry and wet grinding processing of materials. The product has good heat dissipation feature, which can prevent carbonization of diamond particles in high-speed cutting. Nickel-plated diamond with burrs easily combines with resin, thereby achieving better holding force. Service life of tool produced by nickel-plated diamond particles is longer than that of normal type diamond particles.
- Chemical nickel-plated diamond particles: the product is mainly used to fabricate resin-bonded tools for dry and wet grinding processing of materials. In the process of chemical plating,current is not necessary, metal coated layer on the surface of diamond particle is carried out by self-catalytic redox reaction, so the metal layer formed shows features with uniform thickness and dense structure.
- Electro-plated diamond particles with different weight ratio and chemical-plated diamond particles with size in the range of 5-60um are available upon requests; or sizes can be tailored as per customser's requirments.- Copper coated diamond abrasive is mainly used to manufacture resin bonded dry grinding wheels.
