Problems solved by technology

[0002] PVD (Physical Vapor Deposition physical vapor deposition) decorative plating has complex and diverse colors. For some colors (such as golden yellow, rose, brown, etc.) produced by multi-arc ion plating PVD equipment, it is necessary to add N 2 with C 2 h 2 or CH 4 , O 2 Participating in the deposition reaction, its coloring process is unstable, there are problems such as large yin and yang color of the product, large color difference between products in the same furnace, and extremely low yield, so it often needs to be reworked many times, resulting in low production efficiency, increased equipment production load, and power Increased energy consumption, increased production costs, and longer production periods make it difficult to quickly meet customer order needs

Embodiment 1

[0037]Coating TiCN thin film on a metal surface, the color of the film is yellow-orange, and its chromaticity requirements: a* value is 3.60-6.18, b* value is 32.90-37.28.

[0038] Adopt the inventive method to process above-mentioned product, comprise the following steps:

[0039] First, a multi-arc ion plating mechanism is used to deposit a layer of film on the metal surface: the target material is Ti, N 2 Dosage: 260 SCCM, CH 4 Dosage 12SCCM: Deposit for 6 minutes to form base color film layer, use spectrophotometer to measure the product, get a* value = 1.12, b* value = 23.36;

[0040] Then glow oxidize a layer of film on the base color film layer: O 2 Dosage: 320SCCM, vacuum 1.0×10 0 Pa, bias voltage 500V, glow 2min, form an oxide film layer, and obtain a yellow-orange film layer product. The product is measured with a spectrophotometer, and the a* value = 3.71, b* value = 33.28, the color reaches the target color, reaches the lower limit of the color range, and is qu...

Embodiment 2

[0044] Plating TiCN thin film on a metal surface, the color requirement of this film is the same as that of embodiment one, and its processing method is also the same as that of embodiment two, only the glow time of embodiment two is increased from 2min to 4min, and the bias voltage is increased from 500V to 600V. Vacuum up to 2.0×10 0 Pa, an oxide film layer is formed, and a yellow-orange film product is obtained. The product is measured with a spectrophotometer, and the a* value = 6.05, b* value = 37.10, the color reaches the target color, and reaches the upper limit of the color range, which is qualified.

[0045] Anti-chemical test: take 18N sodium hydroxide solution, drop 5 drops on the experimental site on the surface of the prepared film, let it stand for 16 hours, rinse it with water, and observe the condition of the experimental site. It was found that there was no corrosion in the experimental part.

Embodiment 3

[0047] A ZrCN thin film is plated on the surface of a metal, the color of the film is a kind of rose gold, and its chromaticity requirements: a* value is 3.5-5.5, b* value is 25.0-28.0.

[0048] First adopt the inventive method to process above-mentioned product, comprise the following steps:

[0049] Using the multi-arc ion plating mechanism to deposit a layer of film on the metal surface: the target material is Zr, N 2 Dosage: 180SCCM, CH 4 Dosage: 13SCCM: Deposit for 6 minutes to form a base color film layer, the chromaticity index a* value of the film layer=1.09, b* value=18.53;

[0050] Then glow oxidize a layer of film on the base color film layer: O 2 Dosage: 320SCCM, vacuum 1.0×10 0 Pa, bias voltage 500V, glow for 2 minutes, form an oxide film layer, and obtain a rose gold film product. The product is measured with a spectrophotometer, and the a* value = 3.57, b* value = 25.34, the color reaches the target color, reaches the lower limit of the color range, and is q...

Abstract

The invention discloses a PVD glow oxidation decorative coating method. The method includes the steps that the a* value interval and the b* value interval of a target color are provided; a primary color film layer of a certain color is deposited on a to-be-processed surface through a PVD method so that the a* value of the color of the to-be-processed surface can at least reach 10% of the lower limiting value of the a* value interval of the target color and the b* value can at least reach 10% of the lower limiting value of the b* value interval of the target color, wherein the a* value does not exceed 90% of the upper limiting value of the a* value interval of the target color, and the b* value does not exceed 90% of the upper limiting value of the b* value interval of the target color; and oxidation reaction is conducted on the primary color film layer through the glow oxidation method and conduction of the glow discharge process and the oxidation reaction is controlled so that the a* value of the color of a formed oxidation film layer can fall into the a* value interval of the target color and the b* value of the color of the formed oxidation film layer can fall into the b* value interval of the target color. The PVD glow oxidation decorative coating method is uniform in product film layer color and simple in process.

Description

technical field [0001] The invention relates to a coating method, in particular to a PVD glow oxidation decorative coating method. Background technique [0002] The colors of PVD (Physical Vapor Deposition) decorative plating are complex and diverse. For some colors (such as golden yellow, rose, brown, etc.) produced by multi-arc ion plating PVD equipment, N 2 with C 2 h 2 or CH 4 , O 2 Participating in the deposition reaction, its coloring process is unstable, there are problems such as large yin and yang color of the product, large color difference between products in the same furnace, and extremely low yield rate. Therefore, multiple reworks are often required, resulting in low production efficiency, increased equipment production load, and power Energy consumption increases, production costs rise, and production periods are lengthened, making it difficult to quickly meet customer order needs.
