Problems solved by technology

[0002] Glass material plays a decisive role in the field of optical applications because of its easy preparation and price advantage. It can be used to prepare many kinds of optical components because of its easy doping, but its physical and mechanical strength is low, corrosion resistance is weak, and scratch resistance is poor. It cannot be solved by effective technical means, and the poor corrosion resistance of glass cannot be applied in extremely harsh environments and ultra-high temperature environments

Embodiment Construction

[0018] The technical solution of the present invention is further described below in conjunction with the accompanying drawings, but the scope of protection is not limited to the description.

[0019] A kind of preparation method of sapphire-glass laminate, it comprises the following steps:

[0020] (1) Inject He on the surface of sapphire material + Ion layer: He will have kinetic energy and momentum + Ions are implanted into the surface of the chemically mechanically polished sapphire material at a uniform velocity, making the He + Ions accumulate on the surface of the sapphire material to form He + ion layer;

[0021] (2), strip He + Ion layer: He will be implanted + The ionic sapphire material is put into the annealing furnace and filled with inert gas, and then undergoes rapid annealing. The annealing temperature is 350°C-500°C, and the annealing time is 20 ～ 40 seconds until He + Ions overflow from the accumulation layer in the form of gas, and at least one side i...

Abstract

The invention discloses a preparation method of a sapphire-glass laminated sheet. The preparation method comprises the following steps: (1) injecting a He<+> ion layer on the surface of a sapphire material; (2) peeling the He<+> ion layer to obtain an ultrathin sapphire material with at least one damage-free and ultra-smooth face; (3) roasting and welding to obtain a laminated sheet with one damage-free face and the other glass face; and (4) processing. The preparation method disclosed by the invention has the beneficial effects that (1) the processing speed is relatively fast, a lot of re-work in the sapphire material preparation and loading process is saved, and the production cost is lowered; (2) the ultra-smooth laminated sheet with characteristics of glass material and sapphire material is obtained, microcracks in the conventional sapphire processing process are avoided, and the application range of sapphire is expanded, so that the preparation method can be widely applied to the fields of optics, display and substrates.

Description

technical field [0001] The invention relates to a preparation method of a sapphire-glass laminate, belonging to the technical field of material processing. Background technique [0002] Glass material plays a decisive role in the field of optical applications because of its easy preparation and price advantage. It can be used to prepare many kinds of optical components because of its easy doping, but its physical and mechanical strength is low, its corrosion resistance is weak, and its scratch resistance is poor. It cannot be solved by effective technical means, and the poor corrosion resistance of glass cannot be applied in extremely harsh environments and ultra-high temperature environments. [0003] With its high mechanical properties, high stability, and corrosion resistance, sapphire materials are indispensable in the fields of wear-resistant and pressure-resistant industries, aerospace detection, and optical applications in extreme environments. The practical applicat...
