MAGNESIUM ALLOY, METHOD FOR ITS PRODUCTION AND USE Russian patent published in 2021 - IPC C22C23/04 C22C23/02 A61L31/02 A61L27/04 A61L27/58 

FIELD: medicine.

SUBSTANCE: invention relates to a biodegradable implant. The biodegradable implant contains a magnesium alloy containing, wt. % : Zn 4.0 or less, Al from 2.0 to 10.0, wherein the content of Al in the alloy in wt. % is equal to the content of Zn in the alloy in wt. % or exceeds it, the rest is magnesium containing impurities of Fe, Si, Mn, Co, Ni, Cu, Zr, Y, Sc or rare earth elements having ordinal numbers 21, from 57 to 71 and from 89 to 103, Be, Cd, In, Sn and/or Pb, as well as P, contributing to the electrochemical potential difference and/or the formation of precipitation and/or intermetallic phases, with a total content not exceeding 0.0063 wt. %, wherein the alloy matrix is characterized by an increase in the strength of the solid solution due to Al and Zn, as well as the hardening of particles due to intermetallic phases formed from Mg and Al.

EFFECT: invention is aimed at improving the electrochemical stability, corrosion resistance without protective layers, and mechanical strength.
