The invention relates to the technical field of mechanical steel machining, and discloses a method for improving wear resistance and heat resistance of steel. The multi-element alloying method is mainly utilized, manganese, nitrogen and the like are used for replacing nickel, the nickel content is reduced, and meanwhile rare earth elements are added; the affinity of the alloy elements with carbonand nitrogen is quite high, carbide and nitride particles which are distributed in a highly dispersed manner and are extremely high in hardness are formed in the alloy smelting process, the stabilityof the particles is quite high, and the particles cannot be completely dissolved even at the temperature of 1,300 DEG C; and the surface treatment technology is further adopted, oxidation resistance of the steel is improved, the highest heat resisting temperature of the heat resisting steel is improved to 1,200 DEG C-1,300 DEG C from original 900 DEG C-1,000 DEG C, and therefore the application field of the heat resisting steel is greatly expanded.

The invention discloses a non-stick pan coating with graphene material. The non-stick pan coating is composed of a bottom layer and a surface layer; the bottom layer is composed of the following parts by weight of raw materials: 50-90 parts of polytetrafluoroethylene Ethylene / polysulfone blend, 0.5-2 parts modified graphene oxide, 1-5 parts thermochromic pigments, 0.8-1.2 parts modified silicon carbide whiskers, 1.5-3 parts additives and 15-35 parts deionized water; the surface layer is composed of the following raw materials in parts by weight: 35-75 parts of polytetrafluoroethylene resin, 1.5-5 parts of modified calcium carbonate whiskers, 3-8 parts of fatty alcohol polyoxyethylene ether ammonium sulfate, 5 parts of ~10 parts maleic anhydride and 35-60 parts deionized water. Through the reasonable compatibility of different raw material components of the bottom layer and the surface layer, the prepared non-stick pan coating has a better over-temperature prompting function, is more conducive to the control of the cooking temperature, and has excellent high temperature resistance and wear resistance. Extends the life of non-stick pans.
