The invention discloses a manufacturing method for a non-stick coating. The non-stick coating comprises a substrate layer arranged on the inner surface of a pot body, wherein a first transition layeris arranged on the substrate layer; a second transition layer is arranged on the first transition layer; and a surface layer is arranged on the second transition layer. According to the non-stick coating which does not contain fluoride and is in metallurgical bonding, the substrate layer adopts a high-temperature-resistant binder material which is low in aluminum-nickel melting point and is good in wettability, is easily bonded with matrix, and is excellent in adhesion; each layer of paint is mixed progressively, so that the boning performance is good, and therefore, the paint is not liable todrop; a micro structure of the coating continuously changes in a special direction, and mechanical properties and the structure of the coating gradually change in the thickness direction, so that a thermal stress interface ge
