Based on mold steel (GCr12), the relationship between pulse electrochemical machining (PECM) parameters and surface for wetting characteristics was explored. The groove structure with the depth of 0.5mm has been machined on the surface of the steel casting GCr12 by impulse electrochemical machine. Under the best processing parameters, the hydrophobic angle can reach 161.8°. The microstructure, elementary composition, and wettability of the sample were characterized and analyzed by scanning electron microscope (SEM), ultra-depth-of-field microscope, EDS energy spectrum, and contact angle measuring instrument. Single factor experiments are used to explore the influence of pulse electrochemical machining voltage and pulse time on the surface wettability of mold steel (GCr12).
