Detailed description of the invention
It should be noted that, when not clearly limit or when not conflicting, the feature in each embodiment of the present utility model can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
In order to overcome the defect existed in prior art, the utility model provides a kind of non-stick pan, comprises a pot body, and the surface of described pot body has thin layer, and described thin layer formed by the film comprising Cr, Zr, N ternary nitride.
According to the structure of previous embodiment, make use of comparatively low-surface-energy and the automatically cleaning characteristic of the film of Cr, Zr, N ternary nitride, thus realize not sticky effect, and the case hardness of thin layer is high, wearability is good, and spades can be used to cook; The heat resistance of thin layer is also better, and big fire can be used to cook.
Fig. 1 is the structural representation of the non-stick pan according to the utility model embodiment.In the embodiment shown in fig. 1, provide a kind of non-stick pan, it comprises pot body 10, and the inner surface of this pot of body 10 has thin layer 20, can also have transition zone 30 between pot body 10 and thin layer 20.
Wherein, pot body 10 can adopt the materials such as stainless steel, aluminium alloy, al stainless steel composite sheet or carbon steel, and forms through punch forming, and pot body 10 can also have arcuate bottom or flat.
Thin layer 20 formed by the film of Cr, Zr, N ternary nitride.Utility model people finds through prolonged and repeated test, and the film due to Cr, Zr, N ternary nitride has certain amorphous character, thus this film has lower surface energy and self-cleaning characteristic.Thus, utilizing the characteristic of this film, by forming the film of Cr, Zr, N ternary nitride on the inner surface of pot body 10, thus when cooking food, the not viscosity of non-stick pan can be realized preferably, and wearability and heat resistance all effectively improving.
Preferably, in the film of described ternary nitride, the atom number percentage of Cr, Zr, N tri-kinds of elements is respectively 10 ~ 40%, 15 ~ 45%, 28 ~ 58%.For this film, along with N
2the increase of flow, the nitrogen content in film increases, and crystal grain diminishes gradually; When N/Zr atomic ratio increases gradually in film, in film, there will be metastable Zr
3n
4phase and amorphous phase, under higher nitrogen flow, whole film changes amorphous state into; But along with N content increases, film color burn, can lose argenteous metal appearance gradually.
Further, the thickness of the film (i.e. thin layer) of ternary nitride can be 0.1 ~ 25 μm, is preferably 0.1 ~ 20 μm, is more preferably 0.5 ~ 20 μm.If the thickness of thin layer is too thin, then its hardness and wearing no resistance, service life is short; If the thickness of thin layer is too thick, then the production cost of non-stick pan can be caused too high.Utility model people finds through test repeatedly, adopts suitable thin film layer thickness (such as each number range above-mentioned), can find the balance that suitable between hardness and wearability and production cost.Thin layer 20 can pass through the methods such as magnetron sputtering method, multi-arc ion coating method, chemical vapour deposition technique, ion beam deposition or pulsed laser deposition and be formed.
