Materials used in biomedicine must be characterized by controlled biodegradability, sufficient strength and total absence of toxicity to the human body. The search for such materials is, therefore, not a simple task. In this context, scientists have been interested in magnesium for a long time. Recently, using such techniques as positron annihilation spectroscopy, the researchers were able to demonstrate that magnesium subjected to surface mechanical attrition treatment obtains the properties necessary for a biocompatible material.
Materials showing controlled corrosion rate are gaining more and more interest. This applies in particular to biomedicine, where implants made of natural or synthetic polymers are used. Their advantage is that the rate of decomposition can be easily adjusted under physi
