Detailed Description
In this application, it will be understood that terms such as "including" or "having," or the like, are intended to indicate the presence of the disclosed features, integers, steps, acts, components, parts, or combinations thereof, but do not preclude the presence or addition of one or more other features, integers, steps, acts, components, parts, or combinations thereof.
It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
The application is further described with reference to examples of embodiments shown in the drawings.
Referring to fig. 1, an embodiment of the present application provides a method for processing precious metal jewelry, which includes the following process steps.
The material of the precious metal jewelry body is gold or platinum, for example. The shape of the precious metal jewelry body is, for example, earrings, necklaces, rings or bracelets.
103, exciting plasma by using mixed gas containing oxygen and nitrogen, forming a titanium oxide film on the surface of the precious metal jewelry body by using pure titanium as a target through a reactive magnetron sputtering process, wherein element titanium in the titanium oxide film has various valence of plus 6.
Specifically, after glow discharge, mixed gas containing oxygen and nitrogen bombards a pure titanium target, ionized titanium steam is formed on the surface of the titanium target, ionized titanium is accelerated by an electric field to move to the surface of the noble metal jewelry, and then the ionized titanium is oxidized by the oxygen. The nitrogen is used as a protective gas, so that the reaction process is more stable.
The nitrogen is inert gas, and can discharge redundant oxygen in the environment after rushing into the reaction chamber, thereby preventing the quality of the titanium oxide film from being influenced by excessive oxidation reaction. According to the content of oxygen in the diffusion pump, the titanium oxide film can present different color effects. The color effect of the coated product can be changed by changing the oxygen content. Too large oxygen addition can cause too severe pressure change in the reaction chamber and increase process errors; the oxygen addition amount is too small, resulting in insufficient reaction. The gas inlet amount of the nitrogen is not too large, otherwise, the ion amount in the plasma is too large, and the noble metal jewelry body is burnt out. The specific amounts of oxygen and nitrogen may be adjusted depending on the test results.
Specifically, the rf power source may be introduced into the reaction chamber by capacitive coupling. The frequency of the radio frequency power supply is, for example, 27.12 MHz. The noble metal jewelry body is placed on a rotating frame, and the rotating frame is driven by a mechanical motor to rotate.
The inventor tests that titanium in the titanium oxide has a plurality of valences, wherein the valences are + 6.
Because the element titanium has various valence, the surface of the jewelry presents various colors similar to seven colors, and the jewelry is more gorgeous in appearance. Furthermore, the titanium oxide film is hard and stable, is not easy to scratch, has uniform thickness and is corrosion resistant. The reaction raw materials are safe and nontoxic.
Optionally, the titanium oxide thin film has a thickness between 10um and 15 um. The inventor finds that if the titanium oxide film is too thin, the surface of the titanium oxide film has weak scratch resistance and is easy to transmit color (namely, the color of the noble metal jewelry body can be transmitted); if the titanium oxide film is too thick, the content of the noble metal jewelry body is too low, and color is not enough.
Optionally, the air pressure in the reaction chamber of the reactive magnetron sputtering process is not more than 8 × 10-4Pa. The excessive air pressure in the reaction chamber can cause single valence of titanium and single color of the titanium oxide film on one hand; on the other hand, the thickness of the titanium oxide film is not controllable.
Optionally, the temperature in the reaction chamber of the reactive magnetron sputtering process is between 380 ℃ and 440 ℃. The temperature in the reaction chamber is too low, and the element titanium is difficult to oxidize; the bonding force between the titanium oxide film and the noble metal jewelry body is insufficient when the temperature in the world is too high before the reaction.
Optionally, the processing method further comprises: 102, covering a protective layer on part of the surface of the noble metal jewelry body before the reactive magnetron sputtering process is carried out; and 104, removing the protective layer after the reactive magnetron sputtering process.
These two steps are optional. After step 104, the area covered by the protective layer may be subjected to subsequent processes such as wire drawing or polishing.
In other words, the titanium oxide film can be formed on the whole surface of the noble metal jewelry body, and the titanium oxide film can also be formed on part of the surface of the noble metal jewelry. Thus, the shape of the multicolored regions is also customizable.
Optionally, the protective layer is insulating ink or high-temperature gummed paper.
Based on the same inventive concept as the previous embodiment, referring to fig. 2, an embodiment of the present application further provides a precious metal jewelry, comprising: the jewelry comprises a precious metal jewelry body 1 and a titanium oxide film 2 covering the surface of the precious metal jewelry body 1, wherein the element titanium in the titanium oxide film 2 has various valence of plus or minus 6.
Because the element titanium has various valence, the surface of the jewelry presents various colors similar to seven colors, and the jewelry is more gorgeous in appearance. Furthermore, the titanium oxide film is hard and stable, is not easy to scratch and is corrosion resistant. The reaction raw materials are safe and nontoxic.
Optionally, the thickness of the titanium oxide thin film 2 is between 10um and 15 um.
Optionally, the material of the precious metal jewelry body 1 is gold or platinum.
The embodiments in the present application are described in a progressive manner, and the same and similar parts among the embodiments can be referred to each other, and each embodiment focuses on the differences from the other embodiments.
The protective scope of the present application is not limited to the above-described embodiments, and it is apparent that various modifications and variations can be made to the present application by those skilled in the art without departing from the scope and spirit of the present application. It is intended that the present application also include such modifications and variations as come within the scope of the appended claims and their equivalents.
