Abstract

The mechanical properties, corrosion-resistance, and aesthetics of stainless steel make it one of the most important and widely used materials worldwide in the construction, food, and transportation industries just to name a few. In this paper we demonstrate how these properties can be further enhanced by changing the hydrophilic stainless steel surface to be superhydrophilic, superhydrophobic, or superliquiphobic. Creation of these functional surfaces requires hierarchical roughness and chemistry. Roughness is created using various pathways including sandblasting, chemical etching, and nanocomposite coatings. Surface chemistry is controlled using methylchlorosilane, nanoparticles in methylphenyl silicone, and fluorosilane treatment. The broad approach allows for direct comparisons of these pathways. Resulting treatments can create stainless steel surfaces with a hexadecane contact angle of 155° and tilt angle of 7-10°. Discussions of rust-avoidance and coating through condensation reactions are included. Enhanced properties of self-cleaning behavior, anti-icing behavior, wear resistance, and bending resistance are demonstrated on stainless steel 304 L. Stainless steel 430, which is more corrosion prone than stainless steel 304...Continue Reading
