摘要：

In present investigation, a low-cost and facile fabrication route for developing nano-sponge like aluminum coating on carbon steel through flame spraying is demonstrated. The silanization of coating resulted in highly de-wetting state with contact angle > 152 degrees, low contact angle hysteresis and sliding angle (< 5 degrees). The coating also showed low adhesion force of 6 mu N with water. The superhydrophobic coating showed 56 times lower corrosion rate than carbon steel due to high polarization resistance. The coating showed self-regenerative nature during abrasion resulting in persistent superhydrophobicity. High durability was also observed during exposure to rain, weathering, and long-time immersion.
