Parameter Optimization Of The Composite Electro-brush With Nanomaterial And The Performance Of Composite Coating

The composite electrolyte with nanoparticles is prepared on the basis of fast nickel electrolyte under the ultrasonic wave vibration function by appending n-SiC and compound surfactant in this paper. Four factors, the content of nanoparticles in the electrolyte, the content of compound surfactant in the electrolyte ,the brush plating voltage , affecting the performance of composite coatings are optimized in the orthogonal experiments.Test results show that the content of nanoparticles in the electrolyte and the brush plating voltage have remarkable effect on the performance of composite coatings , the content of compound surfactant in the electrolyte and the composite electrolyte initial temperature have little effect on the performance of composite coatings. A mathematical mode of two remarkable factors that effect on the performance of composite coatings is built by nonlinear regression of data of uniform design experiment.The performance of composite coatings is also contrasted with the fast nickel coatings. Results indicate that both of coatings combine with matrix very well and satisfy operation ,the microhardness and wear resistance of nanocomposite coatings are higher than that of fast nickel coatings . the microhardness of nanocomposite coatings is higher 62.1% than that of fast nickel coatings. The wear resistance of nanocomposite coatings is more than three times than that of fast nickel coatings. All these show that nanoparticles can strengthen the coatings. 25 period neutral salt spray corrosion test shows that the corrosion resistance of nanocomposite coatings is superior to that of the fast nickel coatings.
