High release/nonstick coatings, applied over thermally (plasma) sprayed layer, can produce range of surface textures. While coatings are available with average roughness of 50 µin. Ra on smoother end of scale, varying degrees of roughness are available up to 1,000 µin. when high traction is required along with release. Silicone topcoats are optimized for release over durable, wear-resistant, metallized, or ceramic basecoats.
