Micron Diamond Powder



HARIS DIVISION company offers micron powders with the grain size ranging from 60 to 1 micron, obtained by the method of static or centrifugal sedimentation, and sub-micron powders with the size less than 1micron, obtained by the method of classification on super centrifuges from the preliminary processed product of 1micron class.

In technology of production an important part play physico-mechanical impact on grains for the purpose of achievement of the necessary granulometric structure and increasing their isometrics. In the HD lab there was worked through new technological schemes of micron powder manufacturing, which allow adjusting granulometric structure, shape factor, field-performance data of powders. This ensures manufacturing of the vast assortment of high quality products.

The main operational characteristics of micron powders quality is their abrasive ability and roughness of the grinded surface. Abrasive ability features a ratio between mass of removed corundum and mass of used powder at the set mode of test. (Tab. 2) Diamonds with the surface saturated with oxygen, show hydrophilic properties. Their processing with hydroxyl groups increase hydrophility of micron powder surface. This characteristics matter while choosing basic substrate to use it in micron powders for emulsions and diamond compounds.


Electroless nickel coating

Durability and efficiency of abrasive tools is significantly dependant on firmness of grain strengthening in bond. That is why high adhesive characteristics of contact - "abrasive-bonding material", increases tool performance effectiveness.

Due to advanced surface of elecroless nickel coating, crystals are well knit with bonds, which ensures firm retention of grains before complete deterioration during abrasive tool performance. During the electroless nickel cladding process, the surface of crystal is catalytically activated, thus the optimum adhesion between grains and nickel is reached.

It provides intensive heat deflection, emergent from working surface of grains during grinding process, while the coating of crystal itself aids to distribute temperature farther on the bond, which lowers general temperature of processing. Thus suggested coating significantly betters thermo-physical properties of tool.
