I am looking for ceramic coating used on Al-substrate as non-stick and anti wear. Please let me know which coating is most suitable.
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.
Thanks a lot Prof. Lech. Actually, I want to know, which chemical composition (ceramics) can act as non-stick.please let me know
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
Here's a company that manufactures SiO2-based non-stick coatings on aluminium:

very interesting topic, I have a question please, are all cookware toxic?
Dear Shumoos,
not all are toxic. please fell free if you have any question
Armin what is the application for the finished system? Temperature, pressure , general environment. These factors will determine most suitable system
Dear Ronnie,
Actually the samples are used at the form room temperature up 100 C.
Please let me know, if you have any suggestion
There are previous posts relating to cookware coatings. Is this the intended use? Can you openly declare the use of the sample?
Dear Armin can you tell us anymore about the end use of the sample. There are previous posts relating to cookware? Regards Ron
Dear Ronnie,
I am so pleased if you send any date relating to cookware coating
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 ?
Dear Shumoos,
in view of my point, please find ceramic coating e.g Al2O3.
This coating can be manufactured by common methods e.g. Hard Anodizing.
please feel free to keep in touch with me.
