Problems solved by technology

However, it is very difficult for this process to form a uniform and controllable metallurgical bond and color division between metals of different materials. The control requirements are particularly strict. When the temperature is slightly low, there is no real welding, and cracks are prone to occur in the subsequent forging. When the temperature is slightly high, it is easy to melt at the junction and cause color mixing; the third is that the pressure between the metals during the welding process is The weaker ones are not conducive to the welding between metals; the third is that they are heated in the atmosphere for a long time, and the metal joints will inevitably be oxidized

Abstract

The invention provides a method for making yin-yang matching true color separation jewelry. The method includes the following steps: according to the color separation sequence, the dried metal powders of different colors are quantitatively loaded into the mold barrel and cup cavity, and pressed in stages. Compaction; the compacted color separation metal blank is assembled in the bucket cup between the upper paper gasket and the lower paper gasket, and connected between the lower electrode and the upper electrode of the vacuum plasma sintering furnace; at a vacuum degree of 3‑6Pa 1. Pressurizing and sintering the blank under a pressure of 28-35Mpa to obtain a formed jewelry blank; post-processing the sintered and formed jewelry blank. The method of the present invention is simple, low in cost and high in efficiency. The color separation contrast of the prepared yin and yang matching true color separation jewelry is obvious, and complex shapes such as waves, zigzags, Great Walls, and semicircles can be formed on the joint surface, and different metals It presents a uniform and good metallurgical bond, high connection strength, and eliminates the problems of oxidation and blisters at the joints in the existing production methods.

Description

technical field [0001] The invention relates to the technical field of jewelry making, in particular to a method for making jewelry with yin and yang matching true color separation. Background technique [0002] At present, the production of color separation craft jewelry is mainly based on false color separation, and the processes for forming color separation mainly include physical vapor deposition, electroplating, and chemical plating. Seal with varnish, etc., perform color coating on the unsealed area, then remove the closed varnish, and apply varnish to the surface of the coated color film to seal, and then perform another color coating on the uncoated area. In this way, two or more color contrasts can be formed to obtain a color separation effect. However, the outstanding problem of this type of method is that only a very thin color film layer is formed on the surface, which is easy to wear and lose the color separation effect during use. When making true color craft...
