Problems solved by technology

[0003] However, since the standard electrode potential of aluminum or aluminum alloy is very low, and the PVD decorative coating itself will inevitably have tiny pores, therefore, direct plating on the surface of aluminum or aluminum alloy substrates such as TiN layer, TiNO layer, TiCN layer, CrN layer, CrNO layer, CrCN layer or other PVD decorative coatings with anti-corrosion function cannot effectively prevent the electrochemical corrosion of the aluminum or aluminum alloy substrate, and the PVD decorative coating itself will also undergo abnormal discoloration, shedding, etc.

Embodiment Construction

[0019] see figure 1 According to a preferred embodiment of the present invention, the covering member 10 includes an aluminum or aluminum alloy substrate 11 , an amorphous alloy layer 13 and a color layer 15 sequentially formed on the aluminum or aluminum alloy substrate 11 . The covering part 10 may be a covering part of 3C electronic products, and may also be parts of glasses frames, building parts, automobiles and other vehicles.

[0020] The amorphous alloy layer 13 is Fe 70 Cr 10 B 13 x 7 layer, wherein X is selected from any one of phosphorus (P), carbon (C) and silicon (Si). The thickness of the amorphous alloy layer is 2.0-3.0 μm.

[0021] The color layer 15 is a TiN layer with a thickness of 0.5-3.0 μm. It can be understood that the color layer 15 can also be a TiNO layer, a TiCN layer, a CrN layer, a CrNO layer, a CrCN layer or other decorative film layers with an anti-corrosion function.

[0022] Both the amorphous alloy layer 13 and the color layer 15 can be...

Abstract

The invention provides a coated piece which comprises an aluminum or aluminum alloy substrate, an amorphous alloy layer and a colored layer with an anti-corrosion function, wherein the amorphous alloy layer and the colored layer are formed on the aluminum or aluminum alloy substrate in turn; the amorphous alloy layer is Fe70Cr10B13X7; and X is any one selected from phosphorus, carbon and silicon. The coated piece has excellent corrosion resistance and decorative appearance. The invention also provides a manufacturing method for the coated piece.

Description

technical field [0001] The present invention relates to a covering and a manufacturing method thereof. Background technique [0002] Vacuum coating technology (PVD) is a very environmentally friendly film-forming technology. The film layer formed by vacuum coating has the advantages of high hardness, high wear resistance, good chemical stability, firm combination with the substrate, and bright metal appearance. Therefore, vacuum coating is used on aluminum, aluminum alloy, magnesium, and magnesium alloys And stainless steel and other metal substrate surface decorative treatment field is more and more widely used. [0003] However, since the standard electrode potential of aluminum or aluminum alloy is very low, and the PVD decorative coating itself will inevitably have tiny pores, therefore, direct plating on the surface of aluminum or aluminum alloy substrates such as TiN layer, TiNO layer, TiCN layer, CrN layer, CrNO layer, CrCN layer or other PVD decorative coatings wit...
