Abstract

The invention belongs to the technical field of alloy materials, and discloses an alloy material with antibacterial property and high toughness and a preparation method and application thereof. The alloy material comprises a magnesium alloy layer, an intermediate alloy layer and a zinc alloy layer, wherein, the magnesium alloy layer and the zinc alloy layer comprise Ag and Cu; and the intermediatealloy layer is made of magnesium-zinc-silver-copper alloy. The magnesium alloy layer is made of magnesium alloy, and the magnesium alloy further comprises at least one of Nd, Sn or Sr; and the zinc alloy layer is made of zinc alloy, and the zinc alloy further comprises at least one of Nd, Sn or Sr. The alloy material can simultaneously satisfy the characteristics of long-acting antibacterial function, lower degradation rate and favorable mechanical properties, has obvious killing effects on staphylococcus aureus, Escherichia coli, Candida albicans, pneumobacillus, proteus and salmonella typhimurium, and has important application value in the field of medical implant materials.

Description

technical field [0001] The invention belongs to the technical field of alloy materials, and in particular relates to an alloy material with antibacterial properties and toughness, a preparation method and application thereof. Background technique [0002] At present, the common clinical medical implants are mainly made of inert metal materials such as stainless steel, nickel-titanium alloy, and cobalt-chromium alloy. After implanted into the human body, such metal materials will permanently exist as foreign bodies, which will produce toxic ion precipitation, Mechanical traction injury, bacterial infection and inflammation, and secondary surgical removal. [0003] In the prior art, magnesium alloys are used as raw materials for the preparation of medical implant devices, but due to the rapid degradation rate of magnesium alloys in the human body, the application of magnesium alloys as implant materials is limited, and magnesium alloys will induce excretion after being implant...
