Wetting and Corrosion Studies on SS304 Material Surfaces

Corrosion is one of the most unavoidable phenomena which is encountered in most of the aerospace structures. SS304 is well known for its good corrosion resistance property under normal environmental conditions which is widely choose in the joints of most of the aerospace structures. Literature survey shows that the Hydrophobic surfaces has better corrosion resistance characteristic. Here In this work, Hydrophobic surface will be fabricated on SS304 in the shape of micropatterns. Micro patterns like grooves and are made on the surface of SS304 material with the wire electric discharging machining process with varying channel and ridge widths. These patterns which could be helpful for the increment in the contact angle and thereby increasing wetting property of the material. The contact angle of the droplet on the surface is studied deliberately with the assist of sessile drop test. The results of ridge width vs contact angle initially there is an increase in the curve which exhibits a positive slope during that region and then slowly there is a decrement in the curve where there is a negative slope in the decreasing region. the results indicate that as the RW/CW increases initially the contact angle increases a Wetting & corrosion study will be conducted to traverse it under rugged environmental condition and its robustness.
