Diamond micro-powder electroless nickel plating is a very early practical technology, early called diamond metallization plating, diamond micro-powder electroless nickel plating is equivalent to the diamond micro-powder wearing a black coat ( Diamond black powder coat ), when the diamond plating is mainly used for diamond tools, diamond grinding wheel composite plating, in order to enhance the holding force of diamond and tool, abrasive substrate ( we call the binding force ). The current process basically follows the traditional process ( oil removal - coarsening - sensitization - palladium activation - electrolysis nickel plating ).
Diamond and Diamond Powder: The diamond mentioned here is an artificial diamond crystal, which is artificially produced by graphite and catalyst in the mould of the hexahedral top press at high temperature and high pressure. The density is 3.5 g / cm3, and it has the physical and chemical properties of natural diamond. It is the material with the highest hardness at present, and is often used for the production of high hardness tools and abrasives. After crushing, particle size sorting and shape classification, the artificial diamond crystal is used as the determined specification of diamond powder for diamond wire saw. At present, the conventional particle size is from 5 microns to 50 microns, and the classification level is roughly 5 – 10, 8 – 12, 10 – 20, 20 – 30, 30 – 40, 40 – 50...(the unit is micron). Following the mode of using large-size diamond in the coarse line and small particle size diamond in the fine line, by 2015, the minimum diameter of the large-scale production of diamond wire saw bus has reached 50 microns ( 5 wires ), which is used for cutting silicon materials. The minimum bus diameter of diamond wire saw for rare earth permanent magnet cutting is 120 microns ( 12 wires ).
