Due to the good combination of mechanical properties, low density, and the biocompatibility specific to magnesium, the AM50 alloy is a promising material for biomedical applications. However, in order to be widely used in cardiac devices, several issues must be addressed, such as: controlling the corrosion rate, ensuring structural stability during implant operation, and resistance to mechanical and cavitation stresses. The paper presents an experiment which was carried out using a standard 20 kHz vibratory apparatus, in accordance with ASTM G32-2016 standards. The results pave the way for further study of bio-alloys for use in medical fields such as reconstructive surgery. Additionally, the findings contribute to a better understanding of material behavior under aggressive conditions, supporting future optimization of alloy composition and heat treatment processes for improved performance and durability. However, in order to be widely used in cardiac devices, it is necessary to solve problems such as: controlling the corrosion rate, structural stability during the operation of the implant, and resistance to mechanical and cavitation stresses. It is necessary to test the alloy in a liquid medium with physico-chemical characteristics in which the resistance of the AM 50 alloy to the erosive stresses of cavitation is no longer influenced by its degradation property as in aqueous media.
