This paper mainly studied the application of nickel plating liquid as the nickel source, and its application performance was discussed through the following three methods.
The compound coating of Ni-p-ferrite particles was prepared by using nickel plating waste solution as the nickel source:The renewable chemical nickel plating solution was prepared, and its best parameters were optimized. In the base of vortices elements, a equipment which was used to produce the compound coating was designed and manu...
