Nickel-plated copper wire Introduction of nickel-plated copper nickel-plated method:1, electroless nickel: under certain conditions, aqueous solution of metal ions were reduced by reducing agent, and precipitation on the solid substrate surface process. The bath is generally nickel sulfate, nickel acetate, such as the main salt, hypophosphite, sodium borohydride, borane, hydrazine and other reductants, and then add a variety of additives.
Advantages of electroless nickel plating of brass wire:
(1) has a wide range of coverage, for various parts of the complex parts can be more uniform coating.
(2) has a much better plating than the deep plating capacity, can greatly reduce the blind hole plating, deep hole within the coating without the phenomenon.
(3) Electroless nickel plating has better corrosion resistance, abrasion resistance, weldability, uniform coating thickness and higher hardness than plating and brush plating.
2, electroplating: In the pre-plated metal containing salt solution to be coated with the substrate metal as the cathode, by electrolysis, so that the pre-plating solution in the metal cation deposition in the base metal surface to form a coating surface processing method.
3, Brush: with an anode connected to provide the necessary electrolytic plating solution electrode or brush, as a cathode in the workpiece to move on to select the plating method.
Brush plating advantages: brush plating is developed in recent years, a new technology, its biggest advantage is not plating tank, and the deposition rate is faster. Because of its equipment cartridge, easy operation, you can choose a variety of coatings, and has a high bonding strength, etc., so in aviation, ship, railway, electronics and machinery and various vehicle maintenance is widely used, is the national promotion Of a new process.
Brush plating disadvantages: Brush plating in many fields, such as repairing large quantities of large parts of the coating, the production rate is obviously not very high, and compared with the chemical plating, brush plating plating deep plating is also significantly less than electroless plating.
Nickel-plated red copper wire Introduction of nickel-plated copper and bare copper wire difference: nickel-plated copper and bare copper wire in the temperature and electrical properties of almost no difference, the difference is that nickel-plated layer in the air stability is high , Because the metal nickel has a strong passivation ability, the surface can quickly generate a thin layer of passive film, can resist the atmosphere, alkali and some acid corrosion, and nickel coating hardness is relatively high, can improve the surface Of the wear resistance.
