specific Embodiment approach

[0007] Specific embodiments: take the surface decoration of titanium nitride as an example.

[0008] 1. Use a sandblasting machine to sandblast metal and metal alloy workpieces for 15 minutes.

[0009] 2. Coating Take spraying as an example, use UV light-curing epoxy acrylate paint to spray the polished metal and metal alloy workpieces. The spray thickness is 20 microns.

[0010] 3. Put the sprayed metal and metal alloy workpiece into the UV curing oven for curing for 1 minute.

[0011] 4. Polish the surface of the solidified metal and metal alloy workpiece with a fine polishing machine.

[0012] 5. Put the finely polished metal and metal alloy workpieces into the vacuum PVD (vacuum plasma physical vapor deposition) chamber, and the vacuum in the chamber reaches 1.0x10 -3 After Pa, pass argon into the vacuum chamber to keep the vacuum chamber at 1.0x10 -1 Between Pa—2.0Pa, use the ion source to clean metal and metal alloy workpieces for 3—5 minutes, then turn off the ion s...

Abstract

The invention discloses a surface decoration process for metal and metal alloy workpieces and aims at solving the problem of pollution caused in an electroplating process of the traditional surface decoration process for the metal and metal alloy workpieces. An electroplating method for surface decoration of metals and metal alloys is replaced, and a decorative coating obtained by using the process disclosed by the invention is durable, non-dropping, colorful and pollution-free.

Description

technical field [0001] The invention relates to a process for surface decoration of metal and metal alloy, and provides a brand-new method for surface decoration of metal and metal alloy. Background technique [0002] The surface decoration method of traditional metal and metal alloy workpieces is mainly electroplating. The electroplating industry emits a large amount of pollutants every year, including 400 million tons of heavy metal-containing wastewater, 50,000 tons of solid waste, and 30 million cubic meters of acid gas. Currently 70-80% of the state-owned electroplating enterprises have established pollution control facilities, however most of the treatment facilities are outdated and cannot operate. (Only 50% of the facilities in the city can operate, and the rural area is even lower, only 25%. Most township electroplating enterprises have hardly taken any pollution control measures. It has caused great harm to the environment. The post-environmental treatment cost is...
