ELECTROPLATED Co-P BASE CARBON NANOTUBE COMPOSITE COATINGS

Functional groups were obtained on the surface of carbon nanotubes by acid treatment,and high density activated sites were formed on the surface of carbon nanotubes after activation in Sn-containing and Pd-containing solution subsequently.The Co-P-carbon nanotube (CNT) composite coating was prepared by selecting appropriate electroplating conditions.The mechanical properties and corrosion behavior of Co-P-CNT composite deposits are compared with those of Co-P coating.The addition of carbon nanotubes could improve the adhesion and pitting resistance of Co-P coating significantly.
