The coated layer structure of this patent employs multi-layer coating technology, sequentially constructing a high-performance protective layer and an aesthetically pleasing interactive layer from the front to the back of the glass cover plate. The front coating layer uses the cobalt-nickel-aluminum alloy layer 4 as the outermost layer, utilizing its excellent wear resistance, corrosion resistance, and high reflectivity to improve the surface quality of the cover plate; the nickel-aluminum alloy layer 3 serves as a transition layer, enhancing high-temperature resistance and promoting bonding with the next layer; the iron-nickel-cobalt alloy layer 2 further enhances the strength and corrosion resistance of the cover plate. The iron-nickel-cobalt alloy layer 2, the nickel-aluminum alloy layer 3, and the cobalt-nickel-aluminum alloy layer 4 together form a strong anti-scratch barrier, ensuring that the cover plate remains smooth and undamaged under various usage conditions. Each layer of material has high hardness, which significantly improves the wear resistance of the cover plate and extends its service life.
[0029] Please see Figure 1 and Figure 2Furthermore, a thermochromic ink layer 5 is disposed on the lower surface of the glass substrate 1 located in the non-visible area. The thickness of the thermochromic ink layer 5 is 6μm-9μm. It can change color according to temperature changes, increasing the fun and interactivity of the product. At the same time, the screen printing process is flexible and can design a variety of patterns and colors, improving the aesthetics of the product. In this embodiment, the basic color of the thermochromic ink layer 5 is red at 31°C. It is colorless above 31°C and red below 31°C.
[0030] Furthermore, a cobalt-chromium alloy layer 6 is provided on the lower surface of the thermochromic ink layer 5. The thickness of the cobalt-chromium alloy layer 6 is 20nm-30nm. With its high hardness and good corrosion resistance, it effectively prevents the ink layer from being scratched and serves as a transition layer to improve the adhesion with the next layer.
[0031] Furthermore, a cobalt-iron alloy layer 7 is provided on the lower surface of the cobalt-chromium alloy layer 6. The thickness of the cobalt-iron alloy layer 7 is 40nm-60nm, which further enhances the hardness and corrosion resistance of the cover plate, provides additional protection for the ink layer, and forms a good bond with the cobalt-chromium alloy layer 6, thereby improving the overall performance.
[0032] The back coating layer cleverly incorporates thermochromic ink technology. The thermochromic ink layer 5 changes color with temperature, increasing the product's fun and interactivity. Meanwhile, the cobalt-chromium alloy layer 6 and the cobalt-iron alloy layer 7 act as inner protective layers, effectively preventing scratches on the ink layer and ensuring the durability and aesthetics of the design. Through meticulous process control and material selection, the overall structure achieves a tight bond between layers and stable overall performance, providing a high-performance and aesthetically pleasing cover solution for high-end electronic products.
