Description

A blue vacuum coating structure

[technical field]

The utility model relates to vacuum coating, in particular to a blue vacuum coating structure.

[Background technique]

The traditional blue vacuum coating structure vacuum-plates ZrCN film or ALN film on the substrate, wherein the ZrCN film is plated by multi-arc ion plating, and the ALN film is plated by magnetron sputtering. The above blue vacuum coating structure has the following disadvantages:

1. After the plated ZrCN film is touched by human hands, it is difficult to wipe off the fingerprints, and at the same time, the film layer will be corroded by hand sweat and change color.

2. The ZrCN film layer adopts multi-arc ion plating. When the workpiece with mirror effect adopts this process, the energy of the plasma is too high, which will make the mirror surface numb and foggy.

3. When the workpiece coated with ALN film is exposed to the air, the Al in the film is easily oxidized by oxygen in the air, causing the film to change color.

4. For the film structure of ZrCN and ALN, the B value in the LAB is not small enough, that is, the color is not bright enough.

[detailed description]

The blue vacuum coating structure of the embodiment of the utility model is shown in Figure 1, including a base material, a Cr base film, a Cr-Ti transition film, a TinO blue film and an AF transparent protective film. The substrate can be a metal substrate or a ceramic substrate.

The blue vacuum coating structure of the embodiment of the utility model is completed through the following steps:

101. Place the workpiece in the vacuum chamber of the magnetron sputtering coating machine, and fill the vacuum chamber with argon;

102. A Cr bottom film is plated on the substrate surface of the workpiece by vacuum magnetron sputtering;

103. A Cr-Ti transition film is plated on the Cr base film by vacuum magnetron sputtering;

104. Coating TinO blue film on Cr-Ti transition film by vacuum magnetron sputtering;

105. The AF transparent protective film is plated on the TinO blue film by vacuum evaporation.

Among them, the Cr base film can increase the bonding force between the film layer and the substrate; the transition film layer can increase the bonding force of the film layer, and the multi-layer structure produced gradually can increase the density of the film layer.

The range of LAB values for TinO blue film color is: 35 to 70 for L, -10 to 3 for A, and -5 to -30 for B.

Compared with the prior art, the above embodiments of the utility model have the following advantages:

Compared with single-film coating, the film structure of multi-film layer-by-layer coating is adopted to make the film layer denser. The blue film layer is plated with Ti target, and the B value in the film color can reach about -30. Compared with the color plated by Zr target and Al target, this color is more gorgeous. The AF film layer is added at the final stage of the process to effectively protect the blue film layer, making the composite film layer anti-fingerprint and not easy to change color.
