Silicon carbide (SiC) films were deposited on stainless steel (SS), mild steel (MS) and aluminium (Al) from a SiC targeted in a magnetron sputtering system to produce the amorphous SiC coating. Magnetron sputtering is a Physical Vapor Deposition process for deposited material onto substrate by ejecting atom from such SiC and condensing the ejected atom onto SS, MS and Al metals in high vacuum environment. The behavior of the films as corrosion protection barriers in different concentrations of sodium chloride (NaCl) solution in 0.5 M and 1.0 M at different temperatures (30 o C and 50 o C) were evaluated by electrochemical impedance spectroscopy (EIS) measurements. Films on SS exhibited a better corrosion resistance than MS and Al. The weight loss measurement, it shows that uncoated metals loss more weight than coated metals for longer time of immersion. Meanwhile the EIS results also depicted that the polarization resistance, (R p) coated metals indicates higher value compared to uncoated metals. The water salinity and temperatures also showed a significant effect on polarization resistance, (R p ) for both coated and uncoated metals. The R p are decreased with the increased of salinity and temperature accordingly. X-ray diffraction (XRD) used for determination of phase identification. Based on XRD, there are no higher peaks were obtained on SiC, and showed that SiC were confirmed amorphous. It concluded that this study shows corrosion rate of coated metals was decreased obviously compared to uncoated metals and SiC nanocomposite coating performed a significant corrosion behaviors and resistance parameter on different metals.

a b s t r a c tPlasma sprayed ceramic coatings are successfully used in many industrial applications, where high wear and corrosion resistance with thermal insulation are required. The alumina powders were plasma sprayed on AZ31B magnesium alloy with three different plasma spraying parameters. In the present work, the influence of plasma spray parameters on the corrosion behavior of the coatings was investigated. The corrosion behavior of the coated samples was evaluated by immersion corrosion test in 3.5 wt% NaCl solution. Empirical relationship was established to predict the corrosion rate of plasma sprayed alumina coatings by incorporating process parameters. The experiments were conducted based on a three factor, five-level, central composite rotatable design matrix. The developed relationship can be effectively used to predict the corrosion rate of alumina coatings at 95% confidence level. The results indicate that the input power has the greatest influence on corrosion rate, followed by stand-off distance and powder feed rate.
