纳米复合镀层的研究历程

Research Course on Electrodeposited and Electroless Nanocomposite Coatings

总结了纳米复合镀层的研究结果,纳米复合镀层具有硬度高、耐磨损和耐腐蚀的特性,一些纳米复合镀层还具有自润滑性、光催化活性、良好的电接触性及耐高温等性能。纳米复合镀层的基体材料主要是金属镍,还有铜和锌等。纳米粒子材料包括SiC、SiO2、CeO2、金刚石、碳纳米管、Al2O3、Si3N4、TiO2、PTFE、MoS2、WS2、石墨、ZrO2、La2O3、Cr、Ag及Si微粒等。目前,纳米复合镀层的制备技术还不成熟,需要进行更深入的研究。

The reviews on electrodeposited and electroless nanocomposite coatings were summarized. The nanocomposite coatings have the characteristics of high hardness,wear resistance and corrosion resistance, and some of which have the properties of self-lubrication, photocatalysis, electrical contact and antioxida- tion. The based materials for preparing nanocomposite coatings are mostly nickel, zinc and copper, and the nanoparticles used are normally SiC, SiO2, CeO2, diamond, carbon nanotube, A1E 03, Si3 N4, TiO2, FIFE, MoS2, WS2, graphite, ZrO2, La203 , Cr particulate, Ag particulate, Si particulate and so on. At present, the preparation processes for nanoeomposite coatings are still in developing, and need further investigation.
