Embodiment 1

[0034] Such as figure 1 The illustrated anti-scratch superhard glass includes a glass substrate 1, a buffer nano-layer is arranged on the glass substrate, a nano-transition layer is arranged on the nano-buffer layer, a carbon nitride nano-layer 4 is arranged on the nano-transition layer, and the thickness is selected to be 6-20nm . In this embodiment, the buffer nano layer is an aluminum oxide nano layer 2 with a thickness of 50-75 nm, and the nano transition layer is a silicon dioxide nano layer 3 with a thickness of 40-80 nm.

Embodiment 2

[0036] Such as figure 2 The illustrated anti-scratch superhard glass, the difference between this embodiment and Embodiment 1 is that the buffer nano layer is a silicon nitride nano layer 5, the thickness is selected from 40-80nm, and the nano transition layer is a silicon dioxide nano layer 3. The thickness is selected to be 45-68nm, and the thickness of the carbon nitride nano-layer 4 is selected to be 9-20nm.

Embodiment 3

Abstract

The invention discloses anti-scratching extra-hard glass and a preparation method thereof, relating to the improvement and development of amorphous carbon nitride in the manufacturing field of glass. The anti-scratching extra-hard glass comprises a glass substrate, wherein a buffer nanolayer is arranged on the glass substrate, a nanometer transition layer is arranged on the buffer nanolayer, and a carbon nitride nanolayer is arranged on the nanometer transition layer. According to the anti-scratching extra-hard glass, as aluminum oxide and carbon nitride are taken as the transition layer of the glass substrate, the adhesive force of a membrane layer is increased; by buffering the internal stress of aluminum oxide or carbon nitride by virtue of silicon dioxide, the stress difference between the membrane layer in the front part and a carbon nitride layer can be decreased, the rigidity and the adhesive force of the membrane layer are improved, and the abrasive resistance of the membrane is enhanced; the phenomena that a thin layer is broken and falls off and the transmittance of a carbon nitride structural layer system is low caused by the large stress difference between a substrate and layer materials after the carbon nitride structural layer system is plated are solved; the Moh's hardness measurement reaches a level 6.5, and good anti-reflection and anti-scratching effects are achieved.

Description

Technical field: [0001] The invention relates to the field of glass manufacturing, in particular to scratch-resistant superhard glass and a preparation method thereof. Background technique: [0002] In order to enhance the surface strength of glass, for example, it can be achieved by forming a composite layer through coating, etc. In the prior art, silicon nitride coating is used to modify the strength of glass, but it still cannot meet the requirements in special application fields. High glass has become a demand, and the selection and application of materials have always been the bottleneck restricting the further development of this technology. [0003] At present, in the research of hard materials, the advent of carbon nitride quickly caused strong repercussions and huge shocks in the scientific and engineering circles all over the world. [0004] The experiment of preparing carbon nitride was first predicted theoretically in 1989 and succeeded four years later. After a...
