Film plating method of metal cup

Abstract

The invention relates to a coating method for metal cups. It is mainly provided with a turntable in the operating environment. The metal cup to be coated is placed in the turntable, and the metal cup to be coated is correspondingly placed on one side of the turntable. target, and an airway fixture is provided between the target and the turret. The airway fixture is equipped with a gas nozzle corresponding to spraying inert gas on the metal cup, and arcing and discharging after the environment is heated to a certain value. The arc strikes the target to make it ionized, and cooperates with the corresponding angle of the target and the reaction of the inert gas derived from the airway fixture, so that the metal compound of the target is deposited on the surface of the cup body; through the above steps, a uniform coating process is achieved.

Description

technical field [0001] The invention relates to a coating method for metal cups, in particular to an ion coating device and a coating method for surface processing using physical vapor deposition technology. Background technique [0002] Arc ion plating is a kind of physical vapor deposition technology. It is a vacuum ion coating technology that uses vacuum arc discharge as an evaporation source. This method uses an arc to hit the target, so that the target atoms are excited and react with the inert gas. , a technique in which a compound is deposited on the surface of a workpiece. In the arc ion plating technology, the target is not only the evaporation source of the cathode material, but also the ion source of the emitted plasma. Because arc ion plating has the advantages of high ionization rate, uniform coating, best adhesion, and good bonding force between the prepared film and the substrate, it is mostly used on metal hard coatings, especially the requirements wear-res...

Problems solved by technology

[0003] In addition to stainless steel that can be used in the production of cups and bottles among metal materials, there are also other metal materials with high-quality properties such as high strength, low quality, high temperature resistance, low temperature resistance, strong acid resistance, and strong alkali resistance; however, traditional metals When the steel cup is coated, the coating is generally carried out before the overall molding, so that the high-quality metal material is sputtered on the surface of the steel cup by using the coating technology, and after the coating is completed, the forming process such as spinning or welding the bottom of the cup and Combining inner and outer cups and other processes to complete the finished cup; and the above-mentioned process will cause the coating to be damaged during the processing, and the surface of the coating will be damaged to produce defective products.

Then, after coating, the cup will basically show the original color of the coated metal. Therefore, there are not many changes on the surface of the cup, or another coating pattern is required, which will increase the process steps and cost. The above problems and deficiencies are urgently needed for research. One of the breakthrough topics
