Zinc-nickel alloy in the country’s development

A zinc-nickel alloy plating Profile

The zinc-nickel alloy plating, a new plating technology. Coating is no longer a layer of zinc alone but a zinc-nickel alloy layer is plated on the steel surface by electroplating. Nickel belt

Zinc-nickel alloy is doing soluble alloy anode for plating steel zinc alloy. Plating with zincnickel alloys are generally melt into a Zn-2% of Ni alloys, Zn-2% of Ni alloy formulated into a nickel content of 0.04% to 0.09% of the zinc solution, as compared with conventional galvanized layer, the zinc-nickel alloy can effective solution to the active steel extra-thick coating problems and reduce costs, improve the coating corrosion resistance.

Internal quality control of the zinc-nickel alloy plating is primarily to control the proportion of the bath in the zinc, the concentration of nickel, so that the nickel in the coating reaches a certain amount, to do this, the key is to control the zinc, the proportion of the nickel anode area and the sub-control current size (have analytical tools, in order to grasp zinc, nickel concentration). The appearance of good or bad quality selected zinc brightener.

Second, the prospects for the development of the zinc-nickel alloy plating

Zinc alloy zinc cobalt, zinc, iron, zinc and nickel. The highest corrosion resistance of the zincnickel plating layer, the main means of zinc of 90% to 95%, nickel 50% to 10% of the alloy. Such alloys have been practical for many years in many fields worldwide. Such as zinc-nickel alloy sheet provide excellent production of rough in the automotive industry and the computer industry, has greatly improved the corrosion resistance. Zinc-nickel alloy plating automotive components such as the fuel pipe, valves, actuators, transmission components have been standardized in some European and American countries design, a wider range of applications in Japan.
