Abstract:
A layered coating for a sapphire component is described herein. The sapphire component comprises one or more layers of alumina adhered to the surface of a sapphire member. At least the first layer of alumina adheres to the surface of the sapphire member filling all defects in the surface forming a pristine new layer that also provides isolation from damage.
