Problems solved by technology

However, most amorphous magnesium alloys cannot meet the requirements of corrosion resistance in the human body. The current clinical application of amorphous magnesium alloys is mainly reflected in these two aspects. On the one hand, the clinical application performance of amorphous magnesium alloys in medicine There is no systematic evaluation standard and system. Second, in terms of materials science, the amorphous magnesium alloy strips degrade too quickly after being implanted in the body, which leads to the failure of the strips.

Abstract

The invention discloses a ternary MgZnCe amorphous alloy. The ternary MgZnCe amorphous alloy comprises the following components of high-purity magnesium, high-purity zinc and high-purity cerium, an alloy material is prepared according to the proportion of Mg70-XZn30CeX, X is an even number, the diameter of high-purity magnesium particles is 4 * 4 mm, the diameter of high-purity zinc particles is 3* 3 mm, and the diameter of high-purity cerium particles is 2 * 5 mm. According to the ternary MgZnCe amorphous alloy, compared with the traditional amorphous material, the ternary MgZnCe amorphous alloy has higher corrosion resistance, the degradation rate of the ternary MgZnCe amorphous alloy is reduced, and a slow uniform corrosion effect is realized.
