Abrasion, quarrying, and melt-water erosion operate in concert to remove rock at the base of glaciers. Long parallel grooves on glacially polished surfaces connect the polish formation specifically to abrasive wear (Iverson, 1991).Therefore, a simple explanation for glacial polish is that it forms by abrasive removal of material at multiple …

Bluing involves a chemical reaction that produces a thin protective oxide layer on the surface of steel. It provides minimal protection against corrosion and wear. Bluing also wears off over time with use and handling. Cerakote forms a much thicker, more durable ceramic layer that better resists corrosion, abrasion, and oils.
