In this work we show a very promising method of titanium foam preparation with saccharose crystals (table sugar) as a space holder particles. The mixture of Ti and sugar particles was compacted to form a green compacts. In the next step the saccharose crystals were dissolved in the water, leaving open spaces surrounded by metallic scaffold. The sintering of the scaffold leads to foam with typical morphology and porosity. We found that 1:1 Ti/sugar ratio leads to porosities of about 72 % with pore diameter of about 0.8–1.0 mm, when we used 0.8–1.0 mm diameter sugar crystals. The foams morphology was investigated by SEM, porosity and internal structure was investigated using computed tomography and the structure was shown using XRD. The foam morphology pointed theirs potential applications in medical as well as catalyst devices.
In the last half century, great attention has been paid to materials that can be used in the human body to prepare parts that replace failed bone structures. Of all materials, Ti-based materials are the most desirable, because they provide an optimum combination of mechanical, chemical and biological properties. The successful application of Ti biomaterials has been confirmed mainly in dentistry, orthopedics and traumatology. The Ti biomaterials provide high strength and a relatively low Young’s modulus. Titanium biocompatibility is practically the highest of all metallic biomaterials, however new solutions are being sought to continuous improve their biocompatibility and osseointegration. Thus, the chemical modification of Ti results in the formation of new alloys or composites, which provide new perspectives for Ti biomaterials applications. Great attention has also been paid to the formation of nanostructures in Ti-based biomaterials, which has leads to extremely good mechanical properties and very good biocompatibility. Additionally, the surface treatment applied to Ti-based biomaterials provides faster osseointegration and improve in many cases mechanical properties. The special issue “Ti-Based Biomaterials: Synthesis, Properties and Applications” has been proposed as a means to present recent developments in the field. The articles included in the special issue cover broad aspects of Ti-based biomaterials formation with respect to design theirs structure, mechanical and biological properties, as highlighted in this editorial.
