Description
Technical field：
The invention belongs to field of metallurgy, it is related to a kind of biological and medicinal implant material, specifically a kind of magnesium zinc yttrium non-crystaline amorphous metal
Material and preparation method thereof.
Background technology:
Being applied to clinical biomedical metal material at present mainly has stainless steel, cochrome and titanium alloy etc., although their corrosion resistants
Erosion is functional, in vivo can for a long time holding structure it is stable, but such material in vivo easily because of friction generation abrasive dust or because
Slight erosion produces poisonous ion, reduces its biocompatibility.For example：After 316L stainless steels implantation human body, in physiological system ring
In border, the problems such as crevice corrosion, fretting corrosion and fatigue corrosion rupture is produced sometimes, and can be because of reasons such as fretting wears
Discharge Ni2+、Cr3+And Cr5+, so as to cause prosthetic loosening, ultimately result in implant failure；Again for example：Whether it is initial
Ti6Al4V, or subsequent Ti5Al2.5Fe and Ti6Al7Nb alloys, such alloy contains Al elements, and Al elements can cause organ
Damage, cause the symptoms such as osteomalacia, anaemia and neurological disorders；Further, the elastic modelling quantity of stainless steel is about 200 GPa, and titanium is closed
Gold is about 100 GPa, and the elastic modelling quantity of people's bone only has 10~30 GPa, can so produce stress-shielding effect, causes healing
It is slow, or even graft failure.In addition, for the non-degradable material in human body, be temporarily implanted material, this kind of materials application in
Stress-shielding effect, and non-degradable easily are produced during Bone Defect Repari, such as material is temporarily implanted, need to be taken by second operation
Go out, the pain and medical expense burden of increase patient.Magnesium alloy is applied to clinic as medical embedded material with existing

Mg66Zn30Y4Surface Creation protective oxide film, greatly slow down the corrosion of substrate material surface.When anode potential reaches film
After disruptive potential, surface film oxide fracture, alloy substrate continues to corrode.For Mg64Zn30Y6, when current potential increases to about 180 mV,
During 380mv, corrosion current density increase.As a result show, protection oxide-film production twice is had when current potential increases.For
Mg62Zn30Y8, there is three protective oxide film generations in 130mV, 220mV and 380mV.This means in Mg62Zn30Y8
Alloy surface, the protective effect of oxide-film is maximally effective.
