Description
Technical Field
The invention relates to the technical field of vacuum coating, in particular to a vacuum coating method with an antique grain effect.
Background
It is known that the surface of some materials can be coated with a thin film to provide the materials with many new and good physical and chemical properties. In the 70 s of the 20 th century, the methods for plating films on the surfaces of objects mainly include electroplating methods and chemical plating methods. In the former method, an electrolytic solution is electrolyzed by applying current, and the electrolyzed ions are plated on the surface of a substrate as the other electrode, so that the conditions for such plating are that the substrate must be a good electrical conductor and the film thickness is difficult to control. The latter adopts chemical reduction method, the film material must be prepared into solution, and can quickly take part in reduction reaction, and the film-plating method not only has poor bonding strength of the film, but also can not uniformly and easily control the film plating, and at the same time, can produce a large amount of waste liquor to cause serious pollution. Therefore, these two coating processes, which are called wet coating processes, are greatly limited.
Vacuum coating is a new coating technique developed in comparison with the above-mentioned wet coating method, and is generally called dry coating technique. Vacuum coating is an important aspect in the field of vacuum application, and provides a new process for preparing a film for scientific research and practical production by using a physical or chemical method based on a vacuum technology and absorbing a series of new technologies such as electron beams, molecular beams, ion beams, plasma beams, radio frequency, magnetic control and the like. Briefly, a method of evaporating or sputtering a metal, an alloy or a compound in a vacuum to solidify and deposit it on an object to be coated (referred to as a substrate, a substrate or a base) is called vacuum coating.
Vacuum coating techniques generally fall into two broad categories, namely Physical Vapor Deposition (PVD) techniques and Chemical Vapor Deposition (CVD) techniques.
The physical vapor deposition technique is a method of directly depositing a plating material on the surface of a substrate by gasifying the plating material into atoms or molecules or ionizing the atoms or molecules into ions by various physical methods under a vacuum condition. The hard reaction film is prepared by physical vapor deposition method, which utilizes some physical process, such as thermal evaporation of material or sputtering of material surface atoms when being bombarded by ions, to realize the controllable transfer process of material atoms from source material to film. The physical vapor deposition technology has the advantages of good film/substrate binding force, uniform and compact film, good controllability of film thickness, wide application of target materials, wide sputtering range, capability of depositing thick films, capability of preparing alloy films with stable components, good repeatability and the like.
In the current popular products, such as mobile phone middle frames, hardware ornaments, clocks, glasses, locks and the like, ornamentation (such as antique lines) is required to be added on the outer surface of the products so as to improve the aesthetic property, the invention provides a technical scheme which has the antique line effect on the outer surface of the products by a vacuum coating method. Meanwhile, the product has the characteristics of bright color of the film layer, diversified color, wear-resistant quality of the film layer, high hardness, corrosion resistance, environment-friendly process (no waste water or waste gas discharge) and the like.
