The subject is content with future aviation. It has some significance of theory and practice for surface treatment of oceanic product. The present situation and development of technology electroless Nickel-Phosphorus are reviewed on the base of studying a host of paper and books. The advantage and disadvantage of usually electroless Ni-P plating technologies are analyzed and compared by experiment. It is selected one of them as a basic prescription, then added proper complex agents. The ability of solution can be tested by porosity, depositional rate, surface, adhesive strength, corrosion of nitric acid and sulphric acid. The data-processing is adopted advanced Signal Noise Ratic of G.Toguchi instead of synthesis addition estimation. A lot of datas are dealed with C language by computer. The optimized techniological parameters are determined by the highter data of SN from different solution. The questing for electroless Ni-P technology leads to the preferable prescription. The other steps are proceeded ordinarilly. Using the preferable prescription, We can obtained lower porosity; higher deposition rate. Moreover, the time of corrosion resistance to nitric acid is about 52s, resistance to sulphuric acid is 42min.In sum,the integrate properties meet the requirements of industry application.
