WANG Hong yan (Department of Chemistry, Huaiyin Teachers College, Huaian 223001,China)
The structure?morphology and composition of the composite coating of the Ni P PTFE were analyzed by using the methods of XRD? SEM? AES and XPS. The results show that the structure of the Ni P PTFE composite coating is amorphous and the composite deposite is smooth, uniform and good black in appearance. The coating is approximately 3.32?μm thick and has stronger corrosion resistance. The relative atomic percent contents of the coating is Ni 53.01%, P 29.38%, C 1.51%, F 2.88%, O 0.75% and Fe 10.08%, respectively.
