1. A manufacturing process for forming abrasive composite structures on a substrate, the process comprising:
preparing a slurry comprising:
a primary particle content that is less than approximately fifteen percent (˜15%) by volume;
a binder content that is between ˜5% and ˜30% by volume;
a carrier solvent content that is between ˜50% and ˜95% by volume, the carrier solvent being a binary solvent, the binary solvent comprising water and alcohol;
a solvent ratio of alcohol to water that is between ˜0.3 and ˜5.0; and
a viscosity that is between approximately one centipoise (˜1 cP) and ˜2,000 cP;
applying the slurry to the substrate at a wet coating thickness that is between approximately five cubic centimeters per square meter (˜5cc/m2) and ˜500cc/m2; and
drying the slurry at a drying temperature and a drying air flow to produce cracks, the cracks forming abrasive composite structures on the substrate, the drying temperature being between approximately one hundred degrees Celsius (˜100° C.) and ˜190° C., the drying air flow being between approximately 0.7 meters-per-second (˜0.7 m/s) and ˜3 m/s.
