| Summary: | Nano sized TiO2 particles were prepared
by sol-gel method. TiO2 nano particles were
dispersed in zinc-nickel sulphate electrolyte and thin
film of Zn-Ni-TiO2 composite was generated
by electrodeposition on mild steel plates. The effect
of TiO2 on the corrosion behavior and
hardness of the composite coatings was investigated.
The film was tested for its corrosion resistance
property using electrochemical, weight loss, and salt
spray methods. The paper revealed higher resistance of
composite coating to corrosion. Microhardness of the
composite coating was determined. Scanning electron
microscope images and X-ray diffraction patterns of
coating revealed its fine-grain nature. Average
crystalline size of the composite coating was
calculated. The anticorrosion mechanism of the
composite coating was also discussed. |
