Abstract

The invention discloses a biodegradable Zn-Mg-Zr alloy material. The biodegradable Zn-Mg-Zr alloy material is characterized in that the Zn-Mg-Zr alloy material comprises, by mass, 0.0001-10% of Mg, 0.0001-5% of Zr and the balance Zn. The alloy material is low in cost, nontoxic, excellent in mechanical property, low in degradation rate and excellent in biocompatibility. The invention further discloses a preparation method of the biodegradable Zn-Mg-Zr alloy material. The method is easy to implement and low in cost, plate-shaped and rod-shaped materials with different size and cross section requirements can be prepared as required, and the method can be used for preparation of bone lamellas, bone nails and other bone implantation materials as well as cardiovascular stents and other medical materials.

Description

technical field

[0001] The invention belongs to the field of biodegradable metal materials, and in particular relates to a biodegradable Zn-Mg-Zr alloy material, a preparation method and an application. Background technique

[0002] Biometallic materials are widely used clinically. At present, common biometallic materials include stainless steel, titanium alloy and cobalt-chromium alloy. material for permanent implants. However, such materials also have a series of problems during the implantation process, such as stress shielding effect, inflammatory response and heavy ion precipitation. In order to solve the problems caused by the above materials in clinical application, degradable metal materials came into being. The current research directions of degradable metal materials mainly include magnesium alloys, iron alloys and zinc alloys. Magnesium in magnesium alloy is an essential element for the human body and participates in metabolic reactions and the growth of bone t...
