| Description |
Ni based composite coatings containing SiC, Al2O3, YSZ, ZrO2, CeO2 particles have been developed through electrodeposition method. A comparison has been made among these coatings by obtaining them by adopting mechanical and magnetic agitation as the mode of keeping the particles in suspension during electrodeposition. It was observed from the microhardness studies that the coatings obtained with the aid of mechanical agitation displayed higher microhardness compared to the coatings obtained using magnetic stirring. The X-ray diffraction studies revealed that the crystal structure of all the coatings was fcc in nature. The FESEM studies showed that oxide particle reinforced coatings showed smaller grain size compared to Ni-SiC coating. The wear studies showed Ni-YSZ coating displayed better wear resistance compared to the other Ni composite coatings. The polarization studies showed that the corrosion resistance of oxide based Ni composite coatings was better compared to Ni-SiC coating.
