摘要:
A Quaternary Mg—Zn—Ca-based alloy and a heat treatment process for producing bioresorbable bone fixation implants are described thereof. The mechanical and biocorrosion properties of the fabricated Mg-based alloy were improved by combining careful selection of the alloy's chemical composition and subsequent post-shaping process (heat treatments). Heat treatment process is more privileged especially after fabricating the part into its final shape such as in additive manufacturing (3D-printing) and powder metallurgy. In this way, it is possible to produce biocompatible, strong and less corrosive patient-specific bone fixation hardware. Also, such heat-treated Mg—Zn—Ca-based parts can be further coated with various types of biocompatible ceramic coatings for slower and more tailored biocorrosion rates.
