Embodiment 1

[0073] This embodiment prepares a Cu-5Fe-3Zn alloy, and the specific steps are as follows:

[0074] S1: Use pure Cu (99.99wt.%), pure Fe (99.99wt.%), pure Zn (99.99wt%) as raw materials, mix according to different mass ratios, 5wt.%Fe, 3wt.%Zn, and the balance is Cu . Place the weighed raw materials in a drying oven for baking at a temperature of 250°C and a baking time of 20h;

[0075] S2: In the atmospheric environment, place the raw material baked in step S1 in an induction melting furnace, then start the induction heating power supply, and rapidly heat up to 1350 °C at 50 °C / min to obtain a copper alloy melt. The scum on the surface of the melt is removed by a slag pulling tool. When the temperature of the melt is lowered to 1250°C, the melt is poured into the crystallizer by tilting the melting furnace for casting and solidification;

[0076] S3: perform homogenization heat treatment on the Cu-5Fe-3Zn alloy casting billet in step S2 to eliminate alloy dendrite segregati...

Embodiment 2

[0082] This embodiment prepares a Cu-5Fe-0.1Mn alloy, and the specific steps are as follows:

[0083] S1: Use pure Cu (99.99wt.%), pure Fe (99.99wt.%), pure Mn (99.99wt%) as raw materials, mix according to different mass ratios, 5wt.%Fe and 0.1wt.%Mn, the balance is Cu. Place the weighed raw materials in a drying oven for baking at a temperature of 250°C and a baking time of 20h;

[0084] S2: Place the raw materials baked in step S1 in the vacuum induction melting furnace, and vacuum the closed furnace to 10 -2 Pa, then pass high-purity argon into the furnace, then start the induction heating power supply, and rapidly heat up to 1300 °C at 30 °C / min to obtain a copper alloy melt. When the melt temperature drops by 1250°C, pour the melt into the crystallizer by tilting the melting furnace for casting and solidification;

[0085] S3: perform homogenization heat treatment on the Cu-5Fe-0.1Mn alloy casting billet in step S2 to eliminate alloy dendrite segregation and improve al...

Embodiment 3

[0091] This embodiment prepares a Cu-3Fe-1Mg alloy, and the specific steps are as follows:

[0092] S1: Using pure Cu (99.99wt.%), pure Fe (99.99wt.%), pure Mg (99.99wt%) as raw materials, mixed according to different mass ratios, 3wt.%Fe and 1wt.%Mg, the balance is Cu . Place the weighed raw materials in a drying oven for baking at a temperature of 250°C and a baking time of 20h;

[0093] S2: Place the raw materials baked in step S1 in the vacuum induction melting furnace, and vacuum the closed furnace to 10 -2 Pa, then pass high-purity argon into the furnace, then start the induction heating power supply, and rapidly heat up to 1300 °C at 30 °C / min to obtain a copper alloy melt. When the melt temperature decreases by 1270°C, pour the melt into the crystallizer by tilting the melting furnace for casting and solidification;

Abstract

The invention provides a Cu-Fe-X alloy and its preparation method and application. The Cu-Fe-X alloy of the present invention, on the basis of the Cu-Fe binary alloy, adds elements with good biocompatibility such as Zn, Ag, Mg, Mn and Ti through the alloying technology, and combines the heat treatment process at the same time, The content and distribution of alloy elements and Fe phase in the copper matrix are comprehensively regulated, and then the release process of copper ions in the alloy is regulated, which improves the antibacterial and antibacterial properties of the alloy. The invention also provides the preparation method of the alloy and the application of the alloy in the preparation of antibacterial and antibacterial materials.

Description

technical field [0001] The invention belongs to the technical field of copper alloy preparation, and in particular relates to a Cu-Fe-X series alloy and a preparation method and application thereof. Background technique [0002] With the continuous development of biomedical technology, more and more middle-aged and elderly people and even young people rely on implantation or contact with biomedical materials to repair body defects and improve their health, such as bone transplantation and implantation of prostheses. These medical methods often achieve the therapeutic effect through the close contact between the medical device and the patient's body, but at the same time, it also causes great pain for the patient. The reason is that the implant is immersed in the human body for a long time. Complex side effects occur in a constant temperature electrolyte environment and with proteins, enzymes and cells. In addition, medical devices carry bacterial infection and cause health ...
