The influence of sintering temperatures and sizes of dolomite foaming agent on porosity of Mg-6Zn alloy

Magnesium alloys like one of the bioabsorbable implant materials expected to help heal tissue without implant residues, therefore are no need to take the implant for a second surgery. One of the expected performances of metal implants is its ability to support cancellous bone growth, namely porous bone that encloses large spaces and has a spongy nature or appearance, therefore metallic magnesium foams are used in bone implants to approach the natural structure of bones. This study aims to evaluate the effect of dolomite (CaMg(CO3)2) size as a foaming agent to produce porosity on Mg-6Zn alloy. Powder metallurgy is used to produce metallic magnesium foams.
