30%, 56%, 60% Nickel Coated Inustrial Diamond Mesh Powder Grade SCDA

SCDA 120/140 Mesh Diamond Powder 30% 56% Nickel Plating

Description:

SCDA nickel plating adopts Harmony's unique technology to carry out various proportions of electroless nickel plating on SCDA and series products (the weight gain ratio is usually 30%, 56%, 60%), which greatly enhances the relationship between SCDA and particles. The inter-holding force and heat dissipation capacity effectively improve the service life of the grinding wheel and the surface finish of the processed workpiece.

Coated Synthetic diamond abrasive refers to the diamond surface plated with a layer of metal by chemical plating and electroplating methods, in order to improve the adhesion between bond and diamond abrasive, reduce the thermal shock, and protect the diamond abrasive from oxidation to prolong the service life of diamond products. It mainly include three categories: nickel-coated diamond abrasive, titanium-coated diamond abrasive and copper-coated diamond abrasive. Tungstun-coated synthetic diamond can be customized.

Available Sizes:

Feature:
Nickel – 30%,56% or 60% by weight, or any customized specification
Copper – 50% by weight or any customized specification
Used to enhance bond retention
Allows for better heat dissipation
Can be Customized based on customers' demand

Production process
Adopting advanced composite plating process, the product has dense coating and high grinding ability;
Increase the holding force between the abrasives and the bond between the abrasives and reduce the diamond particles from the substrate;
The heat dissipation capability is high, and the thermal shock is slowed down so that the diamond can be carbonized from the impact of the instantaneous high temperature;
In high temperature sintering and high temperature grinding, the coating plays a protective role on the diamond, preventing diamond carbonization, oxidation and so on;
Self sharpening, can maintain good grinding efficiency and service life.
It can improve the electrical conductivity and chemical properties of diamond.

Characteristic:
Bonding strength between diamond/CBN and binding agent increased, also grit's holding strength.
The coated layer can separate air, increase heat dissipation, reduce thermal damage to diamond/CBN.
It can blanket particle defects and uplift their strength.

Application Field:
Chemical nickel coating mainly for resin bond products.
Electro nickel coating mainly for resin bond products.
Copper coating mainly for metal bond products.
Ti coating mainly for metal and ceramic bond products.

Coated Diamond Series:
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: Nickel-coated diamond abrasive is mainly used to manufacture resin bonded grinding tools including dry grinding and wet grinding. The diamond has good heat dissipation ability and control ability, and can adapt to high-speed cutting environment without oxidation.

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.
