It depends on thickness, substrate size and other parameters included in coating's specification. The easiest and cheapest solution is thin film of alumina which can be made on aluminum by anodization. Many physical vapor deposition methods enable to obtain a lot of wear resistant oxides or nitrides. Finally, the coatings of oxides can me made by thermal spray or plasma/laser cladding.
Quick look on internet indicates that non-sticking coatings it can be made by the use of anodized alumina: http://www.t-falusa.com/All+Products/Cookware/Nonstick+Cookware/Products/Ultimate+Hard+Anodized/ULTIMATE+HARD+ANODIZED.htm
But "non-stick" is hardly physical but rather popular definition and I would start with defining the liquids you want not to stick to your coatings and then, to make the research of such ceramics which has great wetting angle to these liquids.
Thank you so much for your suggestion. I think, the company coated kind of polymer e.g PTFE on hard anodized interior in order to make a non-stick surface. I would be so glad, if you have any suggestion for non-stick ceramic
Thanks Mr Armin. I have read that almunium cookware and Cast Iron are toxic while glass cookware it doesn't has chemicals but the dengerouse of being broken which will harm others. While for ceramics I couldnt find enough information . Kindly, what do you recomand ?
