Hydrophilic surface properties created through metal surface micro-texturing. A sponge like aluminum surface soaks up water and spreads it evenly across the surface. Directional metal wetting can be performed using this technique and the flow can even be directed vertically upwards (opposite to the Earth’s gravity). Proper manipulation of surface wettability gives full control over the function of a part. Hydrophilic surface applications include coating adhesion and medical implant osseointegration.
