Description
Technical Field
The invention belongs to the field of alloy materials, and particularly relates to a low-cost purple alloy material, and further discloses a preparation method and application of the purple alloy material in preparation of purple artware.
Background
In the metal artware, purple color is popular with people for a long time due to the characteristics of being heavy and full. However, the conventional purple alloy material for processing purple metal artware is generally synthesized by gold and other metal elements, and particularly gold and aluminum are the most widely used as raw material alloy. Gold-aluminum alloy is usually prepared by taking gold as a raw material, taking aluminum as an alloy element, casting the alloy into purple alloy materials with various shapes according to a certain proportion, and carrying out subsequent deep processing. However, gold is an extremely expensive metal material, so that the processing cost of the purple alloy material is indirectly influenced, and purple metal artware rarely appears in the market due to the influence of price. Therefore, the development of low-cost purple alloy materials is the key point for solving the popularization of purple metal artworks.
Currently, methods and products for synthesizing a violet alloy material based on a low-cost metal material have been developed in the prior art, such as a violet metal material synthesized by using aluminum, zinc, iron, titanium as a main raw material and iron oxide and cobalt blue as violet pigments as disclosed in chinese patent CN107447149 a. Although the processing cost of the traditional purple alloy material is reduced to a certain extent, on one hand, the production cost is still higher, and the mode of adding the purple pigment also enables the color of the alloy material to be unstable, which is not beneficial to the processing stability of the molded metal artwork. Therefore, the development of the purple alloy material with low cost, stable color and excellent processability has positive significance for the development and commercial popularization of purple metal artware.

s2, heating a selected amount of copper until the copper is completely melted, covering the surface of copper liquid with charcoal after the copper is completely melted, isolating oxygen, reducing burning loss, sequentially adding a selected amount of iron, manganese and tin, heating again until the copper is completely melted, and adding a selected amount of tellurium until the tellurium is completely melted;
and S3, pouring the obtained molten mixture into a mold, and cooling and molding to obtain the target purple alloy material.
Optionally, in step S2, the temperature is controlled to be between 1170 ℃ and 1200 ℃.

Experimental example
1. Color value detection
The violet alloys synthesized in the above examples and comparative examples of the present invention were subjected to a chromaticity test after polishing, and the test data are shown in table 1:
TABLE 1 colorimetric test results for purple alloy materials
| L | a | b | |
| Example 1 | 33.41 | 7.63 | -11.63 |
| Example 2 | 33.37 | 7.58 | -11.70 |
| Example 3 | 33.40 | 7.65 | -11.69 |
| Example 4 | 33.26 | 7.21 | -11.72 |
| Example 5 | 33.41 | 7.56 | -11.65 |
| Example 6 | 33.35 | 7.61 | -11.69 |
| Comparative example 1 | 55.44 | 2.23 | 6.25 |
| Comparative example 2 | 46.03 | 4.90 | -4.82 |
| Comparative example 3 | 68.78 | 7.02 | 15.77 |
Note that: an L-brightness axis; a-red and green axis; b-yellow blue shaft
As can be seen from the data in the table, the values of L, a and b in the examples 1 to 6 are respectively 33.26 to 33.41, 7.21 to 7.65 and-11.70 to-11.63, which shows that the colors of the 6 groups of alloys are similar and meet the expected color requirements of the alloys. The values of L, a and b of comparative examples 1, 2 and 3 are greatly different from those of examples, wherein the addition amount of tellurium element in comparative example 3 is zero, the addition amount of manganese is high, the color is off-white, and tellurium element in comparative examples 1 and 2 is purple, but the color is still obviously different from the color value detection data of the embodiment, wherein the proportion of copper in comparative example 2 is reduced, and the purple of the obtained sample is obviously lighter than that of examples 1 to 6. Therefore, in the alloy material, copper and tellurium are main components for providing expected colors, the colors of the alloy can be correspondingly changed according to different tellurium contents, and the colors of expected chromaticity can be obtained by adjusting the proportion of the copper and the tellurium.
2. Alloy performance test
The hardness test is carried out on the purple alloy materials of each embodiment and the comparative example after polishing, firstly, a required sample is cut by using an electric spark numerical control wire cutting machine tool, then, the sample is polished by using abrasive paper with the number of 600# to 2000#, cleaned and dried, finally, the sample is measured on a hardness tester and data are recorded, and the detection data are shown in the table 2:
table 2 hardness test results of purple alloy materials
| Vickers hardness of | |
| Example 1 | 37 |
| Example 2 | 36 |
| Example 3 | 36 |
| Example 4 | 35 |
| Example 5 | 35 |
| Example 6 | 37 |
| Comparative example 1 | 33 |
| Comparative example 2 | 46 |
| Comparative example 3 | 202 |
As can be seen from the above table data, the vickers hardness of examples 1 to 6 and comparative examples 1 and 2 are close, while the hardness of the alloy is significantly higher than the former group as the manganese element in comparative example 3 is increased, so that the addition of manganese element can increase the hardness of the alloy, and as can be seen from the data, the alloy produced by the present invention is not only good in hardness, but also the hardness meets the requirements of the molding process such as engraving.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the invention.
