Zirconia ceramics surface roughness

A ceramic bond coat is almost exclusively used to modify a surface for adhesive bonding. The ceramics include, but are not limited to, alumina, zirconia, titania, spinels, carbides and combinations of these materials." The thermally sprayed bond coatings provide a rough surface on the order of 8 p,m R that has a three-dimensional morphology. Arc-plasma is traditionally used for deposition of the ceramics for these applications.
