Abstract
Superhydrophobic coatings based on calcium stearate were prepared successfully by direct current and pulse electrodeposition on an anodized magnesium alloy. The duty cycle have great effects on the morphology, surface wettability and thickness of the coatings, without affecting the phase composition. The corrosion resistance of the coated substrates in simulated body fluid was investigated as well. The results indicate that the coatings fabricated under different deposition modes and duty cycles exhibit different corrosion resistance. The coating under pulse mode with 50% duty cycle can provide the best corrosion protection for the substrate.
