Diamond Powder Electroless Nickel Plating

Diamond powder electroless nickel plating is a very early practical process technology. It was called diamond metallization in the early days. Nickel plating is introduced in relevant chapters. At that time, diamond plating was mainly used for composite plating of diamond tools and diamond grinding wheels to enhance the holding force (we call it bonding force) of diamond and tool and abrasive substrate. The current common process basically follows the traditional process (oil removal - roughening - sensitization - palladium activation - electroless nickel plating).

 

Since 2015, with the large-scale promotion and application of diamond wire saws in the photovoltaic industry to replace traditional mortar + steel wire cutting silicon materials, diamond wire saws, as a relatively uncommon product, have suddenly become popular, and related industries in the photovoltaic industry have become increasingly popular. The report pointed out that the current output value of the diamond wire saw market is about tens of billions of dollars per year. In recent years, the number of companies specializing in the production of diamond wire saws has also increased, which has brought the diamond wire saw wire continuous plating industry. The great development of diamond wire saw, as the main material of diamond wire saw - diamond micropowder, diamond micropowder electroless nickel plating is also accompanied by this tuyere, and has become a rapidly developing process technology in recent years.

 

Diamond and diamond micropowder: The diamond mentioned here is artificial diamond crystal, which is artificially produced by graphite and catalyst in the mold of a six-sided top press under high temperature and high pressure, with a density of 3.5 g/cm3, with The physical and chemical properties of natural diamond are the material with the highest hardness at present, and it is often used in the production of high-hardness tools and abrasives.

 

After crushing, particle size sorting, shape classification and grading, artificial diamond crystals are used as diamond micropowders with determined specifications and are used in diamond wire saws. The current routine use particle size is between 5 microns and 50 microns The grade is roughly (5-10, 8-12, 10-20, 20-30, 30-40, 40-50, the unit is micron), follow the thick line to use large-diameter diamond, and the fine line use small-diameter diamond. Mode, in May 2019, the diamond wire saw industry held an annual industry meeting in Nanjing. The report at the meeting showed that the minimum diameter of the diamond wire saw busbars produced on a large scale has reached 50 microns (5 wires), which is used for silicon materials. Cutting, diamond wire saw for rare earth permanent magnet cutting Minimum busbar diameter is 120 microns (12 wires).

 

As a synthetic diamond micropowder, there are many parameters such as material quality, shape grade, etc., which will not be introduced one by one. If you want to know more, please contact online customer service or leave a message!
