Embodiment Construction

[0031] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0032] A coating method for preparing an amorphous carbon superhard coating on the surface of a resin and organic glass lens:

[0033] (1) Soak the lens in deionized water, clean it with ultrasonic waves, and finally dry it with nitrogen;

[0034] (2) the lens after drying is packed into frock 6, puts into the frock turntable 5 in the coating machine vacuum chamber 3 immediately, as figure 1 As shown, prevent re-contamination and affect the coating quality. The coating coating equipment at least includes a filtered arc ion source 1, an S-shaped magnetic filter device 2, a vacuum chamber 3, a cold cathode ion source 4, a tooling turntable 5, a tooling frame 6, an air suction port 7, an air inlet 8, a vacuum gauge 9, Magnetic scanning coil 10, graphite cathode 11. Using magnetic scanning, the scanning direction is in the vertical direction of the vacuum chamber, and ...

Abstract

The invention discloses a hard resin lens and organic glass lens surface ultra-hard coat coating method, which comprises the following steps that: an amorphous tetrahedral carbon film is formed on the surface of the lens through pretreatment, glow discharge cleaning, electric arc discharge and carbon ion precipitation, the film has good light transmission and good corrosion resistance, the abrasion resistance of the coated lens is remarkably improved compared with that of the non-coated lens, the coherence force between the amorphous tetrahedral carbon film and the resin and organic glass substrate is strong, the film is difficult to drop of, and the ultraviolet light test indicates that the ultraviolet transmission rate can be effectively reduced by the coat; and the hardness of the coated lens which is prepared with the method can reach more than 85 GPa, the SP3 key structure content in the coat is more than or equal to 85 percent, the friction coefficient is small, the abrasion resistant time is long, and the abrasion resistance is greatly improved.

Description

Technical field: [0001] The invention belongs to the field of surface modification of ion beam materials, and relates to a coating method for preparing an amorphous carbon superhard coating on the surface of a resin and a plexiglass lens, in particular to the ability to prevent lens scratches, improve the wear resistance of the lens, and increase the service life of the lens. A method of coating the surface of a lens to prevent the transmission of ultraviolet light. Background technique: [0002] Resin lenses have the advantages of small weight and easy molding, while plexiglass has good light transmission, corrosion resistance, and easy processing. Therefore, the two have basically become the first choice materials for various optical lenses, glasses and other industrial products. But as a plastic product, the hardness and wear resistance of resin lenses are very poor, while the texture of plexiglass is relatively brittle, the surface hardness is not large, and the wear re...
