Problems solved by technology

However, it is very difficult to process and prepare the alloy wire. Firstly, due to the large difference in the melting point of the four components forming the alloy and the high Zn content, Zn is volatile and lost during the alloy smelting process, which makes the composition of the alloy difficult to be accurate. Second, although the addition of Zn lowers the melting point of the alloy, it also brings brittleness to the material and makes it difficult to process.

Embodiment 1

[0024] A gold-ceramic alloy wire is prepared, and its design composition is Ag 12.75wt%, Pt 1wt%, Zn 12.25wt%, Au balance.

[0025] Specific steps are as follows:

[0026] (1) Using silver and zinc as raw materials, according to the ingredients of Ag-60% Zn, smelting in a vacuum induction melting furnace, filling with argon protection before melting, and solidifying after melting to obtain a silver-zinc master alloy. Three samples were randomly taken from different positions on the silver-zinc master alloy to analyze and detect the actual content of Zn. The results of Zn content are respectively: 59.64%, 60.04%, 59.84%. The results of the three groups are close, indicating that the composition of the synthesized silver-zinc master alloy is uniform;

[0027] (2) Ingot preparation: gold, platinum, silver and silver-zinc master alloy are used as raw materials, and ingredients are prepared according to the following proportions: Ag 12.75wt%, Pt 1wt%, Zn 12.25wt%, Au balance. Me...

[0032] A gold-ceramic alloy wire is prepared, and its design composition is Ag 11.15wt%, Pt 1.5wt%, Zn 13.75wt%, and the balance of Au.

[0033] Specific steps are as follows:

[0034] (1) Using silver and zinc metals as raw materials, according to the Ag-70% Zn batching, smelting in a vacuum induction melting furnace, filling with argon protection before melting, and solidifying after melting to obtain a silver-zinc master alloy. Three samples were randomly taken from different positions on the silver-zinc master alloy to analyze and detect the actual content of Zn. The results of Zn content are respectively: 69.3%, 69.88%, 69.05%. The results of the three groups are close, indicating that the composition of the synthesized silver-zinc master alloy is uniform;

[0035] (2) Ingot preparation: gold, platinum, silver and silver-zinc master alloy are used as raw materials, and ingredients are prepared according to the following proportions: Ag11.15wt%, Pt1.5wt%, Zn13.75wt%, Au ...

Abstract

The invention discloses a gold ceramic alloy wire material and a preparation method thereof. The alloy comprises, by weight, 11-13% of Ag, 1-2% of Pt, 12-14% of Zn, and the balance Au. The preparationmethod of the gold ceramic alloy wire material comprises the following steps of (1) melting silver and zinc as raw materials to obtain a silver-zinc intermediate alloy; (2) conducting smelting and casting on gold, platinum, silver and the silver-zinc alloy as raw materials to prepare a gold ceramic alloy ingot; (3) rolling the ingot into a bar at the temperature of 450 DEG C-650 DEG C at pass deformation of 1%-20%; and (4) conducting hot wire drawing at the temperature of 400 DEG C-650 DEG C at pass deformation of 1%-20%. Through the preparation method, the content of alloy ingredients can becontrolled accurately, the brittleness of materials can be overcome, and the machining process is improved obviously.

Description

technical field [0001] The invention belongs to the technical field of non-ferrous metal alloys, and in particular relates to a gold-ceramic alloy wire and a preparation method thereof. Background technique [0002] With the continuous development of biomedicine, the application of new materials and new technologies continues to expand, and new requirements are constantly put forward for the development of dental materials and connection processes. There are many kinds of dental materials, and the most used ones are metal materials. Although dental metal materials have good stability, excellent biocompatibility, corrosion resistance, wear resistance and mechanical properties, if the connection is not reliable, it may break in the oral cavity and cause new injuries to patients. Therefore, The welding reliability of dental materials has received more and more attention. At present, many dental solders are imported from abroad and are expensive. It is hoped that domestic sold...
