Electroless nickel plating technology has developed rapidly in recent years, and with the electronics, aerospace, oil and other areas more and more applications, electroless nickel plating technology will be further developed. Electroless nickel plating is a nickel salt and a reducing agent in a solution oxidation-reduction reaction, deposited on the surface of the workpiece of Ni-P alloy coating, and simultaneous deposition of hydrogen. Electroless nickel plating workpiece can get in addition to its good wear and corrosion resistance, as well as strong operability, coating thickness uniformity, good chemical stability and excellent performance. In this paper, the reaction mechanism of electroless nickel plating starting by changing the bath composition and the composition of the nickel plating to determine the composition and ingredients for nickel-phosphorus layer deposition rate, corrosion resistance, porosity, hardness, and other effects. Meanwhile in the trial found that the coating quality and pre-plating treatment, plating and after plating processing conditions have a great relationship.
Through testing, and ultimately determine the optimal formula. The formulation process of the plating rate at 12μm / h or so, copper sulfate drip experiment time was 101min, porosity 0.250 /, and its morphology tests. In determining the optimal formula, the amount of load of the bath, the bath life and bath maintenance study, it can be produced in industry.

Chemical nickel plating technology develops rapidly in recent years, and with the application of more and more fields of electronics, aviation, petroleum, chemical nickel plating technology will be developed further. Chemical plating nickel salt and the reducing agent in the solution of the redox reaction occurs, the Ni-P alloy coating was deposited on the surface of workpiece, and hydrogen gas. Chemical nickel plating it except the workpiece can be wear resistance and good corrosion resistance, good performance and strong operability, coating thickness, good chemical stability and so. This paper from the reaction mechanism of chemical nickel plating, by changing the bath composition and composition, to determine the influence of velocity, deposition of Ni-P Layer nickel plating solution for the composition and corrosion resistance, porosity, hardness etc.. Also found in the experiment, the quality of coating and plating pretreatment, plating and post-plating process has the very big relations.
Through the test, and ultimately determine the optimal formula. The formulation of the plating rate is about 12 μ m/h, copper sulfate drop experiment time is 101min, the porosity is 0.250 /, and test its morphology. The optimal formula of plating solution, loading capacity, the life of the plating solution and the bath maintenance were studied, which can be produced in industry
