Problems solved by technology

[0004] It can be seen from the Zn-Se phase diagram that the melting point of Zn is 420°C and the boiling point is 907°C, while the melting point of Se is 220°C and the boiling point is 685°C. The solid solution ability between Se is extremely poor. The existing technology can only prepare micro-nano-scale Zn-Se alloys by deposition method. There is no report of Zn-Se-based alloy prepared by smelting method in the prior art.

Embodiment 1

[0035] The 99.9% pure Zn ingot and the 99.9% pure Se-Ag master alloy were weighed according to the mass ratio of the three elements in the ternary Zn-Se-Ag alloy composition. 220g of Zn ingot and 20g of Se-Ag master alloy were weighed, protected by argon gas, and smelted in a pit furnace at a melting temperature of 650°C, and kept at this temperature for 30 minutes to fully melt the raw materials. After the pouring temperature drops to 550°C, the alloy melt is poured into a steel casting mold preheated to 250°C to obtain an alloy ingot. The ingot was kept at 300 °C for 1 h for homogenization annealing, and then rapidly cooled to room temperature by water cooling. Prepared by wire cutting into a plate sample with a width of 10mm, a length of 40mm and a thickness of 10mm.

[0036]Put the plate into the muffle furnace, set the temperature at 200 °C for 20 minutes, take it out, and carry out rolling. The deformation amount of each pass of the rolling mill is 10%. After each pass ...

Embodiment 2

[0044] Example 2 (cu)

[0045] First, 99.9% pure Zn ingot and Se-Cu master alloy were weighed according to the mass ratio of the three elements in the ternary Zn-Se-Cu alloy composition. Weigh 220g of Zn ingot and 20g of Se-Cu master alloy, and smelted in a pit furnace with argon protection. After the pouring temperature was lowered to 500°C, the alloy melt was poured into a steel casting mold preheated to 250°C to obtain an alloy ingot. The ingot was kept at 300 °C for 1 h for homogenization annealing, and then rapidly cooled to room temperature by water cooling. Wire cutting was used to prepare a plate sample with a width of 10mm, a length of 40mm and a thickness of 10mm.

[0046] Put the plate into the muffle furnace, set the temperature at 200 °C for 20 minutes, take it out, and carry out rolling. The deformation amount of each pass of the rolling mill is 10%. After each pass is rolled, it is immediately put into the muffle furnace for 200 °C heat preservation. 2min, wh...

Embodiment 3

[0049] Example 3 (sn)

[0050] First, 99.9% pure Zn ingot and Se-Sn master alloy were weighed according to the mass ratio of the three elements in the ternary Zn-Se-Sn alloy composition. 220g of Zn ingot and 20g of Se-Sn master alloy were weighed and smelted in a pit furnace under argon protection at a melting temperature of 600°C and kept at this temperature for 30 minutes to fully melt the raw materials. After the pouring temperature was lowered to 500°C, the alloy melt was poured into a steel casting mold preheated to 250°C to obtain an alloy ingot. After the ingot was kept at 300 °C for 1 h for homogenization annealing, a plate sample with a width of 10 mm, a length of 40 mm and a thickness of 10 mm was prepared by wire cutting.

Abstract

The invention discloses a Zn-Se-based alloy material and its preparation method and application. The Zn-Se-based alloy material comprises the following components in terms of mass percentage: 0.1-10wt.% of Se, 0.1-10wt.% of X , the balance is Zn, and the X is selected from at least one of Ag, Cu, and Sn. The preparation method is as follows: mix pure Zn ingots and Se-X master alloys according to the design ratio, melt them in a protective atmosphere to obtain melts, cast them to obtain Zn-Se-based ingots, perform homogenization annealing on the ingots, and then homogenize The ingot after chemical annealing is processed into an alloy plate, and the alloy plate is rolled. After the rolling is completed, aging treatment is carried out under a protective atmosphere, and then water-cooled to room temperature. The Zn-Se-based alloy material prepared by the present invention has excellent Mechanical properties and degradable properties, as well as excellent biological activity, can be used as biomedical implants.

Description

technical field [0001] The invention belongs to the technical field of biodegradable zinc alloys, and particularly relates to a Zn-Se-based alloy material and a preparation method and application thereof. Background technique [0002] Zinc-based biodegradable metal materials are considered as potential new biomaterials that can be used as biodegradable implants, mainly because zinc-based biodegradable metal materials have ideal properties compared to magnesium-based and iron-based alloys. degradation rate. Compared with magnesium- and iron-based materials, zinc-based materials show attractive properties, making them potential alternatives for biomedical applications. However, the mechanical properties of zinc are not enough for most applications, so zinc alloy degradable biomaterials can meet the biocompatibility and degradation properties by adding alloying elements, rapid solidification, heat treatment, and deformation. Effectively improve the mechanical properties of th...
