This invention discloses a method for applying a plasma coating to non-stick pans, relating to the field of plasma spraying technology. The specific steps of this method are: substrate pretreatment and forming, substrate adaptation brazing, surface sandblasting and roughening, plasma cladding for film formation, and post-treatment sealing. This invention achieves a suitable surface state for pans with different substrate types by performing differentiated pretreatments. Iron plate substrates obtain long-term stable rust prevention capabilities through deep nitriding rust prevention treatment, meeting the long-term use requirements of iron plate non-stick pans.
