Problems solved by technology

However, the masking coatings used in the PVD interplating are all ink paints, and various organic solvents are used to synthesize the coatings; in the process of removing the masking coatings after PVD is completed, it is usually necessary to use a large amount of dichloromethane or trichloroethylene to dissolve and remove them. Organic coatings, hazardous to operators and the environment
Preparation of patterns, especially complex patterns, is inefficient, and the interplating process is not environmentally friendly, which is a common problem in the industry at present.

Embodiment 1

[0026] Example 1: PVD inter-plating of stainless steel base golf putter

[0027] Use high-temperature PET film, which can be used for a long time at 200℃, and the film thickness is 0.1mm. Place the high-temperature PET film tightly on the surface of the golf putter, and draw the outline of the inter-plating on the film with a pen; remove the high-temperature PET film and cut out the inter-plating pattern to form the required shielding pattern. For drawing the outline of the inter-plating on the film, it should be noted that when preparing the TiC black film coating, one surface of the golf putter must have a specific non-plating pattern. Attach the PET film to the specific surface of the golf putter, use a pen to draw the pattern at the designated position; then peel off the covered PET film; cut out the specific pattern. Pattern cutting and manufacturing can be mechanized.

[0028] Place one side of the high-temperature PET film shielding pattern (the side is marked, that is, th...

Embodiment 2

[0033] Example 2: PVD inter-plating of titanium alloy base golf head

[0034] PTFE film is selected, which can be used for a long time at 250℃, and the film thickness is 0.06mm. After unfolding the polytetrafluoroethylene PTFE film, stick it tightly to the surface of the golf head. Use a pen to draw the outline of the interlayer on the film; remove the film and cut out the interlayer with a shielding pattern.

[0035] Place one side of the shielding pattern of the PTFE film (the side is marked, that is, the opposite side of the bonding surface) to the polished stainless steel substrate, and put it in a dry sandblasting machine to obtain a rough surface. Use oil-free The compressor, with a pressure of 3 kg, uses 500 mesh corundum sand, which is removed after 10 minutes of sandblasting, and the surface is blown clean with compressed air.

[0036] After cleaning and drying the surface of the golf head workpiece, use the polyimide film shielding pattern that has been processed to cover ...

Embodiment 3

[0038] Example 3: PVD plating of the original faucet with electroplated chromium copper alloy substrate

[0039] The polyimide resin film is selected, which can be used for a long time at 300℃, and the film thickness is 0.12mm. After unfolding the polyimide resin film, stick it tightly to the surface of the faucet workpiece with electroplated chromium copper alloy substrate, draw the outline of the inter-plating on the film with a pen; remove the polyimide resin film and cut out the inter-plating pattern to form the required The shield pattern.

[0040] Use the polyimide resin film and the polished stainless steel substrate to be used together with NaHCO with a concentration of 10g / L 3 After ultrasonic cleaning the organic pattern with the solution for 5 minutes, ultrasonic cleaning in ionized water for 5 minutes; rinse and blow dry. Then place the vacuum furnace turret with the hollow cathode ion gun, pass in argon gas to make the vacuum chamber pressure 0.2Pa, start the hollow c...

Abstract

The invention discloses an environment-friendly method for physical vapor deposition intermediate color film plating. The method comprises the following steps: coating a high-temperature-resistant organic thin film with the thickness of 0.06-0.15mm to a to-be-plated base material, drawing the film to an organic matter according to the space shape and size of an intermediate plating area to form a contour pattern of the intermediate plating area, and cutting out the pattern from an organic matter fabric to finish transfer printing of an intermediate plating pattern; processing the transfer printing pattern to ensure that the transfer printing pattern has relatively strong physical adsorption force with a metal surface; cleaning and drying the surface of a workpiece, covering the intermediate plating area by using the obtained high-temperature-resistant organic matter; coating a needed coating layer on the surface of the workpiece by adopting a physical vapor deposition method; and uncovering the organic matter pattern covering the surface of the workpiece to finish the intermediate plating work. According to the method disclosed by the invention, the high-temperature-resistant chemically stable organic thin film is prepared into the intermediate plating pattern which is attached to the intermediate plating area of the workpiece, the organic thin film only needs to be simply torn off after the implementation of physical vapor deposition coating, and an organic solvent is not used in the process of intermediate plating.

Description

Technical field [0001] The invention relates to a coating method, in particular to an environment-friendly physical vapor deposition intercolor coating method, in particular to a vacuum physical vapor deposition (PVD) coating method. Background technique [0002] The physical vapor deposition method has been widely used in appearance decoration and surface protective coating preparation. There is an increasing demand for inserting surface patterns and icons into PVD coatings. In the process of physical vapor deposition, part of the surface area of ​​the workpiece is deliberately caused to have PVD coating, and some areas are not PVD coating, so that the desired pattern can be realized. One way to achieve the above intention is to use a special stripping method to remove the part of the coating that does not need to be retained after the entire surface is coated with PVD. However, this method is more difficult to implement, and it is necessary to apply the coating to the area whe...
