Hard anodize is certainly a popular process for increasing wear resistance for aluminum. In fact, surface values between 68 and 70 Rockwell C are attainable. But did you also know these finishes can be modified as anodizing non stick coatings?

Anodize coatings have a definite cellular structure. For illustration purposes, imagine individual cells with hollowed centers extending inward, by the millions per square inch. This makes for excellent absorptive properties.

Teflon (PTFE), waxes, oils and other compounds, can be integrated for release (nonstick). And because these compounds can penetrate the ceramic (depending on processing methods) their contributing surface growth is oftentimes negligible. For best results, be sure your service provider understands your requirements.

Depending on cohesive and adhesive characteristics of the sticking compound, hardcoat surface finish may play an important role with release. Most product designers will start by polishing to improve the surface finish. In many cases though, release performance may be improved with surface finish ‘roughness’. Advantages may include minimizing area contact, or even preventing vacuum lock by dissipating trapped air.

Anodizing non stick coatings can offer significant advantage over traditional finishes. In addition to dramatic improvements in wear resistance, newfound surface characteristics will include more uniform surface heat profiles, a critical component in many sticking applications.
