How the above technical problems are solved by the solutions of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, the invention discloses a manufacturing method of a superhard scratch-resistant coating cover plate, which comprises the following steps:
plating a connecting layer 2 on a substrate 3;
sputtering a superhard scratch-resistant layer 1 on the substrate 3 plated with the connecting layer 2; the base plate 3, the connecting layer 2 and the superhard scratch-resistant layer 3 are stacked to form a scratch-resistant cover plate;
the superhard scratch-resistant layer 1 is carbonized X.
The ultrahard scratch-resistant layer 1 and the connection layer 2 formed using the carbonized X are stacked on the substrate 3 to form a cap plate. Only two layers are stacked, the manufacturing process is simple, the stress generated in the manufacturing process is small, the base plate 3 cannot deform, and the manufactured cover plate can meet the use requirements of cover plates with different sizes.
Optionally, sputtering the super-hard scratch-resistant layer 1 on the substrate 3 coated with the connection layer 2 comprises:
placing the substrate 3 plated with the connection layer 2 in a vacuum environment of inert gas;
the substrate 3 plated with the connecting layer 2 is sputtered with an intermediate frequency carbon target and an X target simultaneously to generate carbon atoms and X atoms, the intermediate frequency carbon target and the X target are deposited on the surface of the connecting layer 2, the inert gas is excited into gas ions by a radio frequency ion source, the deposited carbon atoms and X atoms are bombarded by the inert gas ions generated by sputtering to obtain high energy, and the atoms are self-combined to generate carbonized X as the superhard scratch-resistant layer 1.
By adopting the intermediate frequency carbon target and the X target which are sputtered simultaneously, carbon atoms and X atoms can be generated simultaneously, the efficiency is improved, and the formed superhard scratch-resistant layer 1 is more uniform.
Optionally, the X target is any one of aluminum, chromium, silicon, and niobium.
Any one of aluminum, chromium, silicon and niobium is used as an X target material, and one of aluminum carbide, chromium carbide, silicon carbide and niobium carbide can be formed as the superhard scratch-resistant layer 1 after sputtering. Taking silicon carbide as an example, the super-hard scratch-resistant layer 1 has the advantages of wear resistance, cold and hot impact resistance and the like, and can lead the product to have higher wear resistance and scratch resistance.
Optionally, the inert gas introduced in the sputtering process is any one of helium, neon and argon.
The inert gas can be introduced simultaneously in the process of sputtering the carbon target and the X target, or after sputtering the carbon target and the X target. In order to have better sputtering effect, the vacuum environment before sputtering is introduced can be a high vacuum environment. The inert gases such as helium, neon, argon and the like have better stability, so that carbon atoms and X atoms can obtain higher energy, and then the interatomic self-combination can be efficiently completed.
Alternatively, the super-hard scratch-resistant layer 1 has a thickness of 10-100nm.
The super-hard scratch-resistant layer 1 formed by carbonization X has stronger hardness and scratch resistance, so the sputtering thickness is smaller. Too large a thickness of sputtering will stress the substrate 3, causing the substrate 3 to deform. And the thickness of the sputtering is too large, the sputtering time is long, and the sputtering efficiency is reduced. The sputtering thickness is small, the stress generated on the substrate 3 is small, the substrate 3 cannot deform, therefore, the substrate 3 does not need to be reversely deformed before sputtering, the step of pre-deformation is omitted, and the arc edge of the finally prepared cover plate cannot generate chromatic aberration in the 3D state.
Optionally, the substrate 3 coated with the super hard scratch resistant layer 1 has a mohs hardness greater than 8. The carbide X has higher hardness as the superhard scratch-resistant layer 1, is not easy to collide and wear in use as a screen or other panels, and has higher service life and safety performance.
Optionally, the connection layer 2 is a silicon oxide layer, and the thickness of the silicon oxide layer is smaller than that of the superhard scratch-resistant layer 1.
The ultra-thin silicon oxide is used as the connection layer 2 to increase the adhesion of the carbide X to the substrate 3. The thicknesses of the connecting layer 2 and the superhard scratch-resistant layer 1 are very thin, the stress on the substrate 3 is small, and the substrate 3 cannot deform. And the formed 3D cover plate has no different colors at the arc edge, and is suitable for curved and planar products. Because the thickness is very thin, two layers are stacked, the times of the generated reflection and the generated incident light are less, the reflection light and the incident light are not strong when being cancelled, the arc edge of the glass cover plate product has no obvious chromatic aberration, the reflection-enhancing layer is not required to be added, the light-transmitting effect is good, and the visual experience is good.
Optionally, the substrate 3 is made of transparent material, and is any one of glass, resin or flexible PET.
The material of the substrate 3 may be selected according to practical use requirements, and if the cover plate is used as a display screen of an electronic product, the substrate 3 may be selected as a glass substrate, preferably as glass ceramics.
A superhard scratch-resistant coating cover plate is prepared by the manufacturing method of the cover plate.
The cover plate prepared by the preparation method has the advantages of thin thickness, no color difference at the arc edge and better adaptability to different products.
It will be apparent to those skilled in the art that various modifications and variations can be made to the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention also include such modifications and alterations insofar as they come within the scope of the appended claims or the equivalents thereof.
The foregoing description is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical solution of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
