浅谈钛金属在首饰表面装饰中的运用

Study of Application of Titanium on Surface of Decorative Jewelry

钛金属作为一种新型材料在装饰画领域中得到运用,但目前对其在首饰设计中的运用研究甚少。本次研究以钛金属运用到首饰表面进行装饰为目的,通过钛金属单纯氧化、氧化基础上的机械方式、化学蚀刻等制作方式对钛金属表面首饰性装饰进行运用和分析。研究结果表明,在机械方式基础之上,对钛金属表面进行化学蚀刻同时结合单纯氧化可以达到钛金属首饰表面装饰的效果。

Titanium is a new type of materials used in the decoration painting field, and re- search of its application in jewelry design is rare. The surface treatments of titanium decora- tive paintings are divided into three kinds, namely the atmosphere heating oxidation, chemi- cal oxidation and anodic oxidation method. There is a titanium oxide film of microns or even tens of microns thick on titanium surface. Under the condition of this thin film, light reflec- ting from the upper side of the film and penetrating through surface of titanium respectively meet and interfere, which make the surface colour of titanium very beautiful. With the pur- pose of applying titanium to surface decoration, this research uses oxidation, mechanical treatment and chemical etching method based on oxidation to analyze jewelry decoration effects. The oxidation method is to oxidize the surface of titanium repeatedly, which changes the thickness of the oxide layer to present diverse colour effects. Mechanical treatment is generated by applying external force to the metal surface, using manual or power tools to forge, shock, grind or cut before oxidizing the surface to generate the decorative effects. Decorative painting process through chemical etching of titanium mainly refers to applying etching liquid of a certain proportion to the oxide surface, which achieves a unique decorative effect. Technology of titanium decorative painting productions applied to the surface of tita- nium jewelry through methods of oxidation, mechanical treatment and chemical etching isused to get the design and surface decoration effects of metal jewelry. Comparing the three methods, oxidation is simple and rapid and the transition is natural. The disadvantage is that the contrast effect is weak and the scope of oxidization area is hard to control. Mechanical method has advantages of presenting strong industrial manufacturing feelings, while its dis advantage is that it is difficult to produce and costs much material. The advantage of chemi- cal etching method lies in that it is subtle and clear and makes a strong effect. The second oxidation process is more conducive for colour control, and anti-corrosion wax and antiseptic paper can realize transmission among various styles, contrast of colours, textures and thick- ness. The drawback is that material used is pollutive. It is obvious that the chemical etching method is subtler, clearer and can produce texture, contrast of colour and thickness. Mean while the operation is simple and the process is relatively fast. The result shows that based on the mechanical method, the decorative effect on the surface of titanium jewelry can be a- chieved through methods of chemical etching and simple oxidation jointly.
