Abstract
Surface texturing methods are used to engineer surfaces with specific properties in terms of wettability, friction, adhesion, or optical response. Hydrophobic surfaces, i.e., surfaces with minimal wettability, have tremendous applications across various fields; however, texturing methods for developing such surfaces over large areas with complex geometries are limited. This work investigates the process of electrical discharge machining for creating hydrophobic textures on stainless steel (SS304). The effect of EDM parameters such as the discharge current and tool feed on the surface roughness, water contact angle, and tool wear is investigated via experimentation. An increase in the current and tool feed improves the hydrophobicity of the surface by creating a rougher surface while worsening the tool wear rate.
