Abstract (en)
Cookware having a non-stick cooking surface is formed by roughening an aluminium surface, hard anodizing that surface to give a hard anodized layer of 15 to 50 microns in thickness, and finally adhering a non-stick coating, eg. of PTFE, to that surface, optionally with a primer layer between the hard anodized surface and the non-stick coating.
