Program: VEGA
Project leader: Ing. Kováčik Jaroslav PhD.
Annotation:The project deals with the possibility of surface treatment of titanium, which was prepared from titanium powder by low temperature methods of powder metallurgy. It is envisaged to use an energy beam of electromagnetic radiation incident on the surface of the PM titanium either in the form of laser beam or in the form of focused solar radiation. When heated under the working atmosphere, the reaction of titanium with oxygen or nitrogen molecules is assumed and coatings based on oxides, nitrides or their mixtures are expected to be formed. Subsequently, the microstructure and selected properties of the prepared coatings will be studied. The aim is to explore the possibilities of surface treatment of PM titanium, depending on future applications, to prevent surface damage during friction, to improve the surface for biocompatibility and to increase corrosion resistance of PM Ti, which are the most important reasons for surface treatment of usual titanium components.

Štúdium creepových vlastnosti PM Al–Al2O3 kompozitov pomocou small punch testing metódy
Program: VEGA
Project leader: Ing. Krížik Peter PhD.
Annotation:The main aim of this project is studying the creep behavior and determining the creep properties of ultrafine-grained (UFG) Al composites stabilized by nano-scale Al2O3 produced by powder metallurgy (PM), which belong to HITEMAL group, using a small punch test (SPT) method. HITEMAL has been proven for its exceptional thermal stability and mechanical properties at elevated temperatures not normally associated with use of conventional Al alloys and composites. By variations in PM consolidation approach applied in the project various HITEMAL materials with different Al grain structure, and different content, distribution, crystal structure and morphology of in-situ Al2O3 component will be manufactured and used for testing. An emphasis of SPT studies will be put on the following: 1) to elucidate the effect of Al2O3 component on a creep behavior; 2) to determine the effect of Al grain structure on creep behavior; 3) to compare the creep properties measured by SPT with those obtained by standard tensile test

Study of the use of pure magnesium powders for the preparation of biodegradable materials
Štúdium využitia čistých horčíkových práškov pre prípravu biologicky odbúrateľných materiálov
Program: VEGA
Project leader: Ing. Čavojský Miroslav PhD.
Annotation:The project is focused on the study of the possibility of preparation and characterization of biodegradable material on the base of Mg powders with controlled degradation rate. Magnesium-based materials made from ingots have poor mechanical properties and rapidly in the corrosive conditions. As an alternative is to produce the material from Mg powders which can significantly enhance the properties. Powder metallurgy (PM) is a modern method of processing where specific mechanical properties are achieved due to high purity, material structure and controlled porosity. The degradation rate being controlled by surface treatment of powders prior to compaction, or by admixture of a suitable biocompatible material with the healing effect. The material will be prepared by the direct extrusion method, while examination of the effect of the produced native oxides on the extrusion parameters will be necessary. Mechanical and corrosion properties will be examined and in vitro bioassays will be performed.

Annotation:The project is aimed at the experimental determination of the dependence between the parameters of the transverse and longitudinal unevenness of the road and the ride comfort of the driver/co-driver in a motor vehicle. Parameters of the measurement group will be the type and technical condition of the vehicle, the vehicle speed, the road category and the level of longitudinal unevenness. Measurements unique to their range of test sections and of experiment variables will be realized. The aim will be to determine the dependence between the parameters of the transverse and longitudinal unevenness and the whole-body vibration of the vehicle crew. An unevenness indicator using the transverse and longitudinal unevenness parameters will be proposed to take into account the crew-induced whole-body vibration. The results could make a contribution to increasing ride comfort, ride safety and decision-making on the operational capability of communication.

Research of additive manufacturing of biodegradable magnesium alloys and their applications in implantology and regenerative medicine
Výskum aditívnej výroby biodegradovateľných magnéziových zliatín a ich aplikácie v implantológii a regeneratívnej medicíne
Program: SRDA
Project leader: doc. Ing. Škrobian Milan CSc.
Annotation:Nowadays, the current trend in implant production using additive technologies respectively 3D printing is the application of biodegradable or partially degradable materials, that promote osteoinduction and osteoconduction while allowing minimization of surgical procedures. One of the alternative in this field is the use of magnesium alloys that have sufficient mechanical properties, controllable biodegradability, and are transparent for postoperative medical diagnostics as CT and MRI. The main objective of the project is to develop magnesium alloys in the form of powders, with complete elimination of negative properties described in publications such as fast corrosion rate and therefore degradation of material, with release of undesirable hydrogen. At the same time, an SLM additive production machine will be technically adapted for the processing of highly reactive magnesium and its alloys for additional production of samples for further material, mechanical and biological testing. In the final phase of the project, two types of implants will be made from developed alloys. Temporary substitutions of hard tissue, respectively osteosynthetic apparatus in the role of bone support with complete degradation function - biological degradation of the material without the need for reoperation in the form of screws for the area of orthopedics. The research team has an ambition to produce permanent implants with a partial degradation of material and biointegration of the surrounding tissue for neurosurgery and maxillofacial surgery from developed alloys. In the final phase of the project, it is planned to prepare preclinical and clinical experiments as a phase of initiatial application of developed alloys in the form of medical devices into clinical practice.
