Nano carbon fiber is a new type of carbon material has broad application prospects due to its excellent physical and chemical properties, structural reinforcement materials and battery electrode materials, microwave absorbing material and electromagnetic shielding materials and other fields, and in recent years has been widely research. In order to further enhance the electromagnetic properties of the nano-carbon fiber, reinforced with metal, ceramic matrix interfacial bond strength, paper, chemical plating method deposited on the surface layer of Ni-Fe-Co-P alloy coating. The main content of this paper is divided into two parts: First, the sample of iron plates, electroless plating bath formulation, process conditions and the stability of the bath. Weight gain method to calculate the deposition rate of the electroless plating reaction. The experimental results show that, when the other conditions remain unchanged, with the increase of the concentration of nickel chloride, the deposition rate followed increases rapidly. When nickel chloride concentration exceeds 18g.L -1 , the stability of the bath down rough coating dimmed; first reduce the deposition rate increases with increase in the concentration of cobalt sulfate, cobalt sulfate concentration 16g.L -1 , deposition rate, the lowest point, after the deposition rate is gradually increased, but the stability of the bath is decreased, the coating surface is rough, dimmed; With sulfite ammonium iron concentration increases, the deposition rate is gradually reduced; With [Co. 2 ] / [of Fe 2 ] gradually increases, the deposition rate is gradually increased, when the [Co 2 ] / [Fe 2 ] more than 3:1, the coating performance decreases, the sample surface coating is easy to fall off, dimmed; With [Fe 2 ] / [Ni 2 ] gradually increased, the deposition rate decreases gradually; With [Co 2 ] / [of Ni 2 < / sup>] gradually increased, the deposition rate decreases gradually; deposition rate gradually increases as the complexing agent concentration increases, the concentration of the complexing agent in the bath is less than 55g ยท L -1 , the coating surface is rough, gray;, deposition rate is gradually increased with the increase in the amount of ammonia add; With the increase in the reducing agent concentration, the deposition rate increases rapidly. EDS analysis results with [Co. 2 ] / [Ni 2 ] of gradually increasing the nickel content in the plating layer is gradually reduced, the content of cobalt increases gradually large, iron, phosphorus element content changes very little. Thus, by controlling the concentration of metal ions in the bath, the content of the control surface of the coating metal element, to thereby control the performance of the coating. Secondly, the study of the process of a continuous, uniform and Ni-Fe-Co-P alloy coating is deposited in the surface of the carbon nanofiber. Exploit this electroless plating process, after sensitization, the surface of the carbon nanofiber in the activation treatment after deposition of Ni-Fe-Co-P aggregate
