Abstract:

The development of complex nanocomposite materials consisting of different matrices (polymer-like, oxides, intermetallics, liquids) functionalized by different nasnostructured additions (carbon allotropes, magnetic nanoparticles with different organizations, nanostructured semiconductors, etc.) is the aim of this project. The unique combinations of interacting nanophases offeres to the hybrid nanocomposite material new or enhanced proprieties of high interest for applications. In this context, according to the previous experience of the involved teams, the complex project (formed by 4 component projects) is focused on the development of new optimized nanocomposite systems to be included in experimental demonstrators or final products to be transferred to economical companies. The project will contribute both to an increased scientific visibility of the partners as well as to enhancing the institutional performances by the development of new technical and scientific capacities.

Abstract:

The project objective is to obtain orthopaedic implants from a new biomaterial (Gum type alloy) nanostructured by Severe Plastic Deformation having antibacterial nanocoatings. The project provides advanced solution with powerful societal impact by developing temporary implants, new compression staples with multidirectional gripping, able to ensure better fixation of bone fragments especially at the multiple fractures. For achieving project goals, scientific activities will be developed concerning the following: design of the alloy composition; alloy synthesis; study of the alloy deformability; thermomechanical alloy processing by High Speed High Pressure Torsion method; complex characterization of the ascast/processed alloy; antibacterial nanostructured coatings deposition; in vitro advanced characterization by electrochemical studies to asses the corrosion behaviour of the alloy and of the coatings; in vitro characterization by biological cellular response analysis; finally, implants design and execution. In addition, the project aims to demonstrate the applicability of the research results and validation both manufacturing and characterizing technologies on a number of test implants.

Abstract:

The project describes the manufacturing process of an original multifunctional device, generating linear displacements for self-adaptive compensation of the clearance caused in some machine parts under functioning conditions. The prime novelty of the project are the active elements produced by Fe-Mn-Si shape memory alloys (SMAs) with ultrafine/nanometric structure, obtained by severe plastic deformation procedures, meant to enable both fragile-ductile transition and high temperature stability through structural heredity. Fe-Mn-Si SMA elements will undergo “training” thermomechanical processes which induce the final behavior of the materials with temperature or stress variations, thus acquiring a quantifiable multifunctional potential (expressed via work). Strain recovery by shape memory effect, under prescribed temperature conditions, allow displacement development as an effect of the deformation of lamella and/ or disk-like elements. The manufacturing technology of the elements includes the setting of two “shapes” by conventional plastic deformations. The “hot” shape corresponds to the parts deformed within the austenitic domain through deep drawing with a curvature radius r0 which depends on the shape memory properties of the material, while the “cold” shape involves a deformation in martensitic domain with a curvature radius r > r0, inversely to hot deformation. With temperature increase, trained elements behave like actuators which recover their “hot” shape by work development, according to an accurate linear self-adapting displacement. The association of trained elements in the framework of coupled modules provides flexibility and multifunctional character to the developed system. The general purpose of the project is to promote an advanced technological solution for producing some elements with role of self-adaptive actuators and for their assembling within an original functional-constructive variant, able to generate accurate controlled displacements.
