    Teflon is a brand of PTFE, often used as a generic term for PTFE. The metallic substrate is roughened by abrasive blasting, then sometimes electric-arc sprayed with stainless steel. [8] [9] The irregular surface promotes adhesion of the PTFE and also resists abrasion of the PTFE. [10] Then one to seven layers of PTFE are sprayed or rolled on.

    en.wikipedia.org/wiki/Stainless_steel

    Stainless steel, also known as inox, corrosion-resistant steel (CRES), and rustless steel, is an iron-based alloy containing a minimum level of chromium that is resistant to rusting and corrosion. Stainless steel's resistance to corrosion results from the 10.5%, or more, chromium content which forms a passive film that can protect the material ...

    The coefficient of friction of plastics is usually measured against polished steel. [36] PTFE's coefficient of friction is 0.05 to 0.10, [27] which is the third-lowest of any known solid material (aluminium magnesium boride (BAM) being the lowest, with a coefficient of friction of 0.02; diamond-like carbon being second-lowest at 0.05).

  9. Surface chemistry of cooking - Wikipedia

    en.wikipedia.org/wiki/Surface_chemistry_of_cooking

    The self-healing properties of stainless steel are such that when part of the protective oxide layer gets scratched off, more of the steel reacts, leaving the surface protected again. Stainless steel is considered stainless because it has at least 11% chromium by mass.
