ABSTRACTThe electrodeposition of nickel/silicon carbide (Ni/SiC) composite films formed from modified Watt's bath solutions under potentiostatic conditions on steel substrates was investigated. The effects of deposition potential, pH, variable concentration of SiC in suspension, and additives, such as coumarin and EDTA, on the nickel nucleation and growth transients, as well as on the composition and morphology of Ni/SiC films are described. Improved Vickers microhardness and corrosion resistance of these composite films were found in comparison to those of particle-free deposits.

Sulfamate Bath

Nickel-Silicon Carbide (Ni-SiC) composite coating has been prepared by two electrode electrochemical co-deposition technique in nickel sulfamate bath. The Cetyltrimethylammonium bromide (CTAB) was added in bath as cationic surfactant whereas saccharine as a grain modifier. The effect of current density during deposition was systematically studied and optimized to get homogeneous surface texture with utmost microhardness and deprived coefficient of friction. The result revealed that 60 mA/cm2 current density was found to be the optimum current density which showed the highest microhardness of 590 ± 10 Hv and lowest coefficient of friction with regular surface morphology.Journal of Institute of Science and TechnologyVol. 21, No. 1, 2016, Page : 82-85

Different Content

High-temperature mechanical properties, machinability, oxidation resistance and thermal shock resistance of different content of carbon particles modified silicon carbide composite ceramics (Cp/SiC) prepared by pressureless sintering techniques were studied. Adhesion of Cp/SiC to melted glass under 1000°C was also observed. The results showed that 15-Cp/SiC had the optimum machinability and it also did not adhere to melted glass at high temperature. And flexural strength, hardness, and fracture toughness of 15-Cp/SiC is 136.5MPa, 274.6kgf/mm2, 2.58MPa•m1/2 respectively. The good performance of Cp/SiC made it possible to be used as high temperature glass fixture, which means that Cp/SiC can not only improve the service life of fixture materials, but also broaden the application fields of SiC ceramics.
