Abstract In accordance with the requirement of industry for plating layer with high corrosion or wear resistance property,the method of chemical plating and the composition of plating solution are analyzed,the corrosion rate is determined,and the performance of the plated layer is investigated. Several affecting factors for corrosion rate are discussed,and some processes are optimized.Accordingly,electroless plated nickel-phosphorus layer on various metal surface with better corrosion resistance comparing with electro plated layer.
