Abstract

The invention discloses an ultra-hard waterproof, anti-fouling and wear-resistant coating film. The ultra-hard waterproof, anti-fouling and wear-resistant coating film comprises a substrate layer, a film layer, an anti-fouling layer and an air medium layer, wherein the film layer, the anti-fouling layer and the air medium layer are successively arranged on the substrate layer; the thickness of thesubstrate layer is 0.05-0.8 mm; the film layer is formed by alternately arranging nitridosilicates and oxide of silicon, and the thickness of the film layer is 300-650 nm; the thickness of the anti-fouling layer is 10-20 mm; the air medium layer is an air medium with the refractive index NA equal to 1, and the wavelength gamma c is equal to 550 nm; and a color film layer is arranged between the film layer and the anti-fouling layer and is champaign gold or silver or brillant blue. Compared with the prior art, the ultra-hard waterproof, anti-fouling and wear-resistant coating film has the outstanding effect that the film layer not only has gorgeous color, but also has quite high mechanical strength and corrosion resistance, and after the anti-fouling layer is added, the hand feeling and the durability of a plated piece are obviously improved.

Description

technical field [0001] The invention relates to the technical field of optical coatings, in particular to a superhard waterproof, anti-fouling and wear-resistant coating, a coating process and a detection method thereof. Background technique [0002] Recently, traditional glass mobile phone covers and fingerprint identification materials have been gradually replaced by ceramic substrates with better dielectric properties. However, due to the relatively complex surface properties of ceramic materials, traditional electroplating or silk screen methods cannot meet the requirements of plating parts. Increasingly refined appearance and durability. The vacuum coating technology involved in this patent can deposit layer by layer on the ceramic substrate to form a superhard film showing a specific color. The coated film layer is firmly combined with the surface of the substrate, and changing the material and physical thickness of the film layer can achieve a specific color on the su...
