In recent years, biodegradable alloys have made their presence felt in a wide variety of fields, such as aeronautics, automotive and medical fields. Biodegradable alloys are considered to be the 3rd generation of biocompatible alloys, replacing classic alloys such as stainless steels and Co-Cr alloys. The paper aims to study the structural aspect and identify some mechanical characteristics of magnesium-calcium alloys used as biodegradable materials in the medical field. It has been observed the formation of a eutectic compound at the limit of magnesium grains and the relative constant value of the apparent coefficient of friction with increasing Ca concentration.
