Problems solved by technology

[0003] However, since the most obvious disadvantage of magnesium or magnesium alloys is poor corrosion resistance, and the PVD decorative coating itself will inevitably have tiny pores, therefore, direct plating on the surface of magnesium or magnesium alloy substrates such as TiN layer, TiNO layer , TiCN layer, CrN layer, CrNO layer, CrCN layer or other PVD decorative coatings with corrosion resistance cannot effectively prevent the electrochemical corrosion of the magnesium or magnesium alloy substrate, and the PVD decorative coating itself will also Occurrence of discoloration, shedding, etc.

Embodiment Construction

[0021] see figure 1 , the housing 10 of a preferred embodiment of the present invention comprises a magnesium or magnesium alloy substrate 11, magnesium silicide (Mg silicide) formed on the magnesium or magnesium alloy substrate 11 in sequence 2 Si) layer 13 and color layer 15. The casing 10 can be a casing of a 3C electronic product, and can also be a frame of glasses, a construction piece, and a part of a vehicle such as an automobile.

[0022] The Mg 2 The thickness of the Si layer 13 is 300-1000 nm.

[0023] The color layer 15 is an electrical insulating layer with anti-corrosion properties. The color layer consists of sequentially formed Mg 2 Titanium dioxide (TiO 2 ) layer 151 and silicon dioxide (SiO 2 ) layer 153. The TiO 2 The thickness of layer 151 is 50-150nm, the SiO 2 The thickness of layer 153 is 50-150 nm.

[0024] The Mg 2 Both the Si layer 13 and the color layer 15 can be deposited and formed by magnetron sputtering. It can be understood that the M...

Abstract

The invention provides a shell, which comprises a magnesium or magnesium alloy substrate, and a magnesium silicide layer and a color layer formed orderly on the magnesium or magnesium alloy substrate. The color layer is a corrosion-resistant electric insulating layer. The shell has good corrosion resistant performance and decorative appearance. The invention further provides a manufacture method of the shell, comprising the steps of: providing the magnesium or magnesium alloy substrate; forming the magnesium silicide layer on the magnesium or magnesium alloy substrate by magnetic sputtering; and forming the color layer on the magnesium silicide layer by magnetic sputtering.

Description

technical field [0001] The invention relates to a casing 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 most obvious disadvantage of magnesium or magnesium alloys is poor corrosion resistance, and the PVD decorative coating itself will inevitably have tiny pores, therefore, direct plating on the surface of magnesium or magnesium alloy substrates such as TiN layer, TiNO layer , TiCN layer, CrN layer, CrNO layer, CrCN layer or other PVD decorative co...
