Description
Technical Field
The invention relates to the technical field of vacuum coating, in particular to a black and blue PVD decorative film and a preparation method thereof.
Background
The PVD decorative coating film adopts physical vapor deposition technology to form a layer of uniform, smooth and metal-like surface on the surface of the substrate. The film has high wear resistance and corrosion resistance, and can improve the appearance effect of the product, so that the film is attractive.
The PVD decorative film has various colors including silver, gold, black, gray, blue, purple, coffee, multiple colors and the like. With the increasing diversity of color demands of consumers, more diversified decorative film plating products are also introduced in the market, so that higher requirements are put on the development of the decorative film plating process with rich colors.
Among the many decorative films, black and blue gives a mystery and profound feel, is an attractive color and is highly appreciated by consumers. Under the general condition, people often adopt a metal aluminum target and a titanium target to co-sputter, and simultaneously, the blue film is prepared and obtained by introducing nitrogen, but the L value in the Lab value of the color is larger, the brightness requirement cannot be met, and meanwhile, the corrosion resistance of the TiAlN film component is lower, and the corrosion resistance requirement of high-end electronic products cannot be met. Meanwhile, currently proposed black and blue films are prepared by adopting metal targets (chromium, titanium and the like) and carbon source gases (methane, acetylene and the like) through a PVD method, and the preparation method has certain defects in color debugging, and mainly comprises that the prepared product is not blue enough, cannot meet the demands of consumers, and is insufficient in wear resistance of a color film layer and the like.
Disclosure of Invention
The invention aims to overcome the technical defects and provide a black and blue PVD decorative film and a preparation method thereof, so as to solve the technical problems of insufficient color and poor wear resistance of the PVD decorative film in the prior art.
In order to achieve the technical purpose, the technical scheme of the invention provides a black and blue PVD decorative film and a preparation method thereof.
The black and blue PVD decorative film is deposited on the surface of a substrate, and comprises a priming layer, a transition layer and a color layer which are sequentially arranged, wherein the priming layer is a Cr layer and is arranged between the substrate and the transition layer for improving the adhesive force of a coating; the transition layer is a CrSiC layer, the sum of Cr and Si atom contents in the transition layer is larger than C atom content, and the Cr atom content is larger than Si atom content and is arranged between the priming layer and the color layer to improve the binding force of the coating; the color layer is a CrSiC layer, the sum of Cr and Si atom contents in the color layer is smaller than C atom content, cr atom content is smaller than Si atom content, and the black and blue tone can be controlled.
First, the sum of Cr and Si atom contents in the transition layer is larger than the C atom content, and the Cr atom content is larger than the Si atom content. This composition arrangement allows the transition layer to have a relatively high refractive index and to absorb a portion of light of a specific wavelength, especially red and green light. This results in the absence of red and green components in the light spectrum passing through the transition layer.
Next, the sum of the Cr and Si atom contents in the color layer is smaller than the C atom content, and the Cr atom content is smaller than the Si atom content. This allows the color layer to have a lower refractive index and to scatter the remaining light. Since the transition layer absorbs a portion of the red and green light, the blue component of the spectrum is relatively high after passing through the color layer. At the same time, the path of light reflected in the color layer increases due to the presence of scattering, resulting in the surface of the color layer appearing darker.
Thus, the blue-black color of the film surface is caused by the absorption of red and green light by the materials in the color layer and the scattering of blue light. This combination gives a relatively high blue component of the spectrum through the film, and a low red and green component, thus giving the appearance of black and blue.
Preferably, the thickness of the priming layer is 100-500 nm, the thickness of the transition layer is 300-1500 nm, and the thickness of the color layer is 300-1000 nm.
