Description
Summary:Due to the compatibility problems of biomaterials currently used in biomedicine, the effect of Silicon addition to the innovative TiMoZr alloy has been investigated. The mechanical properties of these two alloys and their corrosion resistance in simulated body fluid were analyzed in order to recommend them for the manufacture of medical instruments. After the application of the corresponding techniques, the metallographic study shows only the two-phase structure of the sample with silicon, which has lower modulus of elasticity values and higher Vickers microhardness values. The sample without silicon offers a higher resistance to corrosion, although these values between the two samples are very close.
