Description of the Invention: [Technical Field] The present invention relates to the field of coating technology, and in particular to a substrate having a multilayer film structure. [Prior Art] As a film processing technology, the coating mainly includes a plasma plating method, a magnetron sputtering coating method, a vacuum evaporation method, a chemical vapor deposition method, and the like. Ichiki, M. et al., May 2003, 2003, Symposium on Design, Test, Integration and Packaging of MEMS/MOEMS, Thin film formation-a fabrication on non-planar surface by spray coating method A method of spraying a non-planar film. The reactive magnetron sputtering coating method is applied to metal or glass substrates to form a multi-layer film structure with high metallic texture and colorful fullness. It has been widely used in consumer electronic products. _ At present, in order to improve the hardness and wear resistance of the coated layer, it is common to increase the number of layers of the film to be coated and the thickness of the film. However, when the coating layer is a metallic alloy and the substrate to be plated is a glass substrate, there is a difference in physical properties such as a lattice structure and a coefficient of expansion between the substrate to be plated and the coating layer. The ability to bond the layer to the substrate to be plated is reduced, resulting in the disadvantage that the coating layer is not worn out and is easily peeled off. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a glass sheet having a multilayer film structure to solve the above problems by the solution of the present invention. A substrate having a multilayer film structure will be described below by way of examples. A substrate having a multilayer film structure comprising a substrate layer, an iron film layer, and a transition film disposed between the substrate layer and the plating layer. The transition film contains chromium oxide, and the chromium content thereof is reduced from the surface of the substrate layer to the surface of the coating layer. Compared with the prior art, the substrate layer is bonded to the coating layer by the transition film to improve the bonding force between the substrate layer and the outer layer film and the transition film, thereby improving the structural stability of the substrate having the multilayer film structure. [Embodiment] Hereinafter, a base having a multilayer film structure will be further described in detail with reference to the accompanying drawings and the plural embodiments. Referring to Fig. 1', the substrate 10' provided in the first embodiment of the present invention includes a substrate layer η, a ruthenium layer 12 and a transition film 13 between the material layer 11 and the plating layer 13. The base material layer 11 is made of a metal material such as metal aluminum, titanium or an alloy (e.g., stainless steel, Mingqin alloy). This includes a surface m on the outermost side for setting the plating. " soil 9 11 The mineral film layer 12 is placed on the substrate layer u, and the root layer can be plated with different materials as needed. The axial film layer 12 includes an outermost film relative to the outer layer 121, which may be composed of one material: = film (i.e., the single layer layer is an outer layer film), or may be a multilayer film formed earlier. The outer layer film 121 adopts::, the layer of the early layer film is superimposed. The sheet is made of 12, and the non-metal material is formed into a carbon, glass or ceramic. The ceramic is a metal compound containing nitrogen, carbon or oxygen, for example: titanium nitride, 5 carbon chromium, gasified magnesium. The opposite sides of the transition film 13 are respectively associated with the substrate layer 11 and the plating layer 12 . In this embodiment, the opposite sides of the transition film 13 are in contact with the outer surface 111 and the outer layer film 121, respectively. The transition film 13 contains chromium and nitrogen, and has the chemical formula: CrNx, X is 1 or less and 0 or more. The chromium content of the transition film 13 is reduced from the surface of the substrate layer to the surface of the coating layer. Since the chromium content in the transition film 13 is higher than that of the & high (e.g., chromium, Cr), it is metallic, and when the nitrogen content is high (e.g., chromium nitride, CrN), it is non-metallic. Therefore, the physical properties (such as: lattice structure, expansion coefficient, etc.) of the material of the transition film 13 and the substrate layer 11 and the outer layer film 121 at the contact interface are similar, and the substrate layer 11 and the outer layer film 121 and the transition film 13 are improved. The bonding force increases the structural stability of the substrate 10 having the multilayer film structure. Of course, the transition film 13 may include CrN having a higher hardness to increase the hardness of the entire plating layer. The transition film 13 can be prepared by vacuum coating. In the embodiment 10, a chromium gas is used as a starting material, and a mixed gas of argon gas and nitrogen gas is introduced into the vacuum plating chamber, which is plasma-formed by an electromagnetic field and combined with chromium to form a transition layer containing nitrogen and chromium. . In the coating process, the transition layer 13 having the desired properties can be obtained by adjusting parameters such as the ratio of argon to nitrogen in the true cavity and the sputtering speed. For example, when a mixed gas of argon and nitrogen having a high nitrogen content is introduced (for example, argon gas is introduced at a rate of 25 cubic centimeters per minute and nitrogen gas is introduced at a rate of 99 cubic centimeters per minute), a transition can be formed. The region of the film 13 having a high nitrogen content, that is, CrN. Conversely, when the nitrogen content is lowered or the nitrogen gas is stopped (for example, argon gas is introduced at a rate of 25 cubic centimeters per minute, and nitrogen gas is stopped), a region containing a high chromium content in the transition film 13 is formed. Namely: Cr. In addition, the amount of nitrogen (adjusted between 0 and 99 cubic centimeters per minute) can be adjusted according to the required hardness of the transition film 13. Referring to FIG. 2, a substrate 20 having a multilayer film structure according to a second embodiment of the present invention has a structure substantially the same as that of the substrate 10 having a multilayer film structure provided by the first embodiment, and the difference is that the substrate layer twenty one. The A substrate layer 21 is made of a non-metal material. The non-metallic material can be glass or ceramic. The ceramic is a metal compound containing nitrogen, carbon or oxygen. In order to ensure the bonding force of the film layer, the substrate 20 is provided with a first matching layer 24 between the substrate layer 21 and the transition film 23. The opposite sides of the first matching layer 24 are in contact with the outer surface 211 and the transition layer 23. The first matching layer 24 contains nitrogen and chromium, and the nitrogen content is higher than the nitrogen content of the transition film 23, such as chromium nitride. The transition film 23 is in contact with the outer layer film 221 on the side facing away from the substrate layer 21. Referring to FIG. 3, a substrate 30 having a multilayer film® structure according to a third embodiment of the present invention has a structure substantially the same as that of the substrate 10 having a multilayer film structure provided by the first embodiment, and the difference is that the coating layer 32. The outer layer film 321 of the plating layer 32 is a metal film. In order to secure the bonding force of the film layer, the substrate 30 is provided with a second matching layer 35 between the outer layer film 321 and the transition film 33. The opposite sides of the second matching layer 35 are in contact with the outer layer film 321 and the transition film 33. The second matching layer 35 contains nitrogen and chromium, and the chromium content is higher than the chromium content of the transition film 33, such as chromium. In addition, if the substrate layer is made of a non-metal material and the outer layer film is a metal film, the substrate can be provided with a first matching layer and a second matching layer between the substrate layer and the transition layer and the transition layer and the outer layer 201024463 film, respectively. To obtain better film adhesion. In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law.
