Abstract
A process that controls sizes, shapes, and densities of the abrasive composite structures on a substrate by controlling the properties of the slurry (more than just the number and size of the particles in the slurry), controlling wet coating thickness of the slurry on the substrate, and controlling drying conditions of the slurry. Similar to how mud dries and cracks when arid and parched, the controlled drying of the slurry produces cracks as the slurry dries. These cracks form structures that are separated by grooves (or valleys), which form the abrasive surface.
