Laboratory technology for obtaining magnesium from record purity, which is based on multiple (3-fold) repetition of sublimation of magnesium under high vacuum with a yield of about 80% at each stage. The technology of melting and casting of magnesium alloys type WE43 on the basis of ultrapure magnesium and REM additives with a purity of 99.99% has been developed. The structure of ingots of magnesium alloys smelted in different conditions is studied. The blanks of alloy WE43 high purity with a fine-grained structure (3 μm) and a high combination of strength and ductility. Mechanical and acoustic characteristics of WE43 alloy are determined. X-ray studies established the value of OCD in deformed alloys. Based on a comparison of our data on the minimum rate of biocorrosion of the studied ultrafine-grained alloy (d = 1-2 μm) in physiological solution with literature data, we can conclude that the rate of corrosion in the body (in vivo) will be in the range of 0.1-0.3 μm / day. In order to improve the corrosion properties and increase the stability of the implant was proposed modification of the elemental composition of the alloy WE43, resulting in a new one
magnesium-based alloy doped with silver (WE43 + 1% Ag).
