Squeeze Cast AZ31 Magnesium Alloy Long Term Degradation Analysis in Hanks' Solutions

Popis výsledku v původním jazyce

Magnesium alloys with a low specific weight, relatively high specific strength and damping capacity are considered as perspective biodegradable materials for implants. The rate of degradation significantly influences their using for various biomedical applications. In this work, the long term degradation behavior of AZ31 magnesium alloy prepared by squeeze casting method was investigated to determine its performance in a physiological environment which was simulated by two different Hanks' balanced saltsolutions (HBSS) without and with Ca, Mg. The immersion test was used for study of degradation behavior of AZ31 magnesium alloy during exposition time in range of 0-1000 hours. The degradation rate after immersion in Hanks' solutions was calculated fromthe weight loss, and chemical compositions of degradation products were determined and examined via atomic spectroscopy; change of pH during degradation process was also determined in HBSS. The degradation of samples of AZ31 magnesium al
