The outer surface of the aluminum alloy panel substrate is provided with a color functional layer, and the color functional layer comprises a color nitride layer positioned on the inner side and a transparent protective layer positioned on the outer side. The thickness of the color nitride layer is 0.5-5.0 μm, and the thickness of the transparent protection layer is 1.0-5.0 μm. The color nitride layer is Ti_aZr_bAl_1-a-bN, wherein a is more than or equal to 0.25 and less than or equal to 0.50, b is more than or equal to 0.03 and less than or equal to 0.10, and the transparent protective layer is Al_1- _cZr_cAnd O, wherein c is more than or equal to 0.10 and less than or equal to 0.15, and the values of a, b and c are measured by an EDS elemental analysis method.

In the invention, the color nitride layer in the color functional layer can endow the metal panel with golden yellow color appearance, and the composition of the color nitride layer is Ti_aZr_bAl_1-a-bN_xWherein a is more than or equal to 0.25 and less than or equal to 0.50, b is more than or equal to 0.03 and less than or equal to 0.10, x is more than or equal to 0.50 and less than or equal to 1.50, and the values of a, b, 1-a-b and x respectively represent the atom (mol) content of Ti, Zr, Al and N. The values of a, b and x can be measured by an EDS elemental analysis method. The inventors of the present invention have found that by adding an appropriate amount of Zr element to a nitride layer, it is possible to compare with Ti_aAl_1-aThe N-nitride layer can obtain a golden color tone without adding Zr elementThe color tone of the pixel is shifted to blue (b value becomes smaller) and to red (a value becomes larger), and the golden color tone of the present invention cannot be obtained. Compared with the traditional pigment coating (or polymer color layer), the color nitride layer obtained by the invention has more excellent stability and weather resistance, and no organic volatile or other toxic substances are released in the preparation and application processes, so that the color nitride layer is safer. In addition, Ti_aZr_bAl_1-a-bThe N color layer also has high hardness, has excellent wear resistance, and can prevent accidental friction and loss, thereby being maintained for a long period of time. In the color nitride layer, the limitation of the content of nitrogen within the above range is advantageous for obtaining a golden color tone, and the limitation of the content of nitrogen within the above range is also advantageous for the stabilization of the color tone, that is, for the color tone of the color nitride layer to be maintained stable under a humid, heated or dry environment. Regarding the content of nitrogen, it can be obtained by controlling different process parameter conditions according to the preparation method. Composition for the color nitride layer is Ti_aZr_bAl_1-a-bN_xThe color of (A) is represented by a Lab color system, and the L value of the color is 72.0-89.0, the a value is-10.0-5.0, and the b value is 65-80; preferably, the color nitride layer is expressed by Lab color system, and has an L value of 75.0-85.0, an a value of-5.0 and a b value of 70-80; more preferably, the color nitride layer is expressed by Lab color system, and has an L value of 78.0 to 85.0, an a value of-3.0 to 5.0, and a b value of 73 to 80. The thickness of the color nitride layer is not particularly limited in the present invention. Preferably, the thickness of the color nitride layer is 0.5-5.0 μm, which is beneficial to displaying color tone and presenting better color tone effect when the thickness of the color nitride layer is increased, and is beneficial to keeping stable color tone for a long time, but when the thickness of the color nitride layer is more than 5.0 μm, the internal stress of the coating is increased, and the risk of peeling off the coating is increased. In the present invention, the color nitride layer is prepared by a vapor deposition method, and as examples of vapor deposition, CVD, PVD or the like, CVD (e.g., PECVD, DC-PCVD, RF-PCVD, MPCVD or the like), PVD (e.g., vacuum evaporation, sputtering, ion plating) and the like can be used. For vacuum deposition according to evaporation sourceAnd resistance heating evaporation, electron gun heating evaporation, induction heating evaporation, arc heating evaporation, laser heating evaporation, electron beam heating evaporation and the like can be selected. As the sputtering, direct current sputtering, radio frequency sputtering, magnetron sputtering, unbalanced magnetron sputtering, reactive magnetron sputtering, pulse sputtering, or the like can be selected. The ion plating may be radio frequency discharge ion plating, cathode arc ion plating, magnetron sputtering ion plating, or the like. Ion plating is preferably used, and for example, a cathode arc ion plating or magnetron sputtering ion plating method can be conveniently used to obtain a color nitride layer having a uniform and homogeneous film thickness, and N can be selected for forming the nitride layer₂、NH₃And the reactive gas source is adopted, in addition, Ar inert gas can be adopted when the sputtering ion plating process and the like are adopted, and the molar content of the nitrogen in the color nitride layer can be conveniently adjusted by controlling the reactive gas source by adopting the ion plating process.

In the invention, the transparent protective layer in the color functional layer can provide protection for the color nitride layer, particularly can prevent penetration of other ions such as O and the like, so that the color nitride layer can keep the original color for a long time without discoloration. Specifically, the composition of the transparent protective layer is Al_1-cZr_cOy, wherein c is more than or equal to 0.10 and less than or equal to 0.15, and y is more than or equal to 1.2 and less than or equal to 1.5. The values of c, 1-c, y represent the atomic (molar) contents of Al, Zr, O, respectively. The values of c and y can be measured by an EDS elemental analysis method. By adding Al to_1-cZr_cThe introduction of an appropriate amount of Zr element into Oy can reduce or prevent oxygen permeation in a heated or humid environment, so that a protective layer can be provided for the color nitride layer below the Zr element, thereby endowing the color functional layer with good weather resistance and discoloration resistance, and the transparent protective layer also has high hardness, so that the color functional layer can be endowed with higher wear resistance and scratch resistance. The thickness of the transparent protective layer is not particularly limited in the present invention. Preferably, the thickness of the color nitride layer is 1.0-5.0 μm, and when the thickness of the color nitride layer is less than 1.0 μm, although protection can be provided for the color nitride layer, long-term discoloration resistance of the color nitride layerThe energy may be decreased, and increasing the thickness of the transparent protective layer, while being advantageous for providing long-term protection of the color nitride layer, may result in increased internal stress of the coating layer when the thickness is greater than 5.0 μm, and may increase the risk of peeling of the coating layer. In the present invention, the transparent protective layer is formed by a vapor deposition method, and examples of vapor deposition include CVD, PVD, CVD (e.g., PECVD, DC-PCVD, RF-PCVD, MPCVD, etc.), PVD (e.g., vacuum evaporation, sputtering, ion plating), and the like. For vacuum evaporation, resistance heating evaporation, electron gun heating evaporation, induction heating evaporation, arc heating evaporation, laser heating evaporation, electron beam heating evaporation, and the like can be selected according to different evaporation sources. As the sputtering, direct current sputtering, radio frequency sputtering, magnetron sputtering, unbalanced magnetron sputtering, reactive magnetron sputtering, pulse sputtering, or the like can be selected. The ion plating may be radio frequency discharge ion plating, cathode arc ion plating, magnetron sputtering ion plating, or the like. Ion plating is preferably used, and for example, a cathode arc ion plating or magnetron sputtering ion plating method can be conveniently used to obtain a transparent protective layer having a uniform and homogeneous film thickness, and further, to form Al_1- _cZr_cOy layer can be selected from O₂As a reactive gas source, in addition, Ar inert gas may be used when a sputtering ion plating process or the like is used, and the molar content of oxygen therein can be conveniently adjusted by controlling the reactive gas source using the ion plating process.
