On the project

Chemical reactions during sintering of titanium and hydroxyapatite have limited the usefulness of such composites. However, the idea of combine the mechanical strength of titanium with the bioactivity of hydroxyapatite is still attractive to develop high strength and light composite materials for the treatment of bone defects. This project proposes a new concept to achieve the goal based on the low temperature precipitation of hydroxyapatite. The hypothesis are that biomimetic processing of hydroxyapatite will avoid the decomposition of both hydroxyapatite and titanium and that the chemical activation of titanium will promote its covalent bonding with hydroxyapatite. Natural inspired three-dimensional structures will be fabricated by robotic assisted deposition to study the hydroxyapatite/titanium interface and mechanisms of failure. The results will generate significant advancements in fundamental aspects of ceramic/metallic composites, beyond the deposition of coatings.

Description in Czech
Chemické reakce v průběhu slinování titatnu a hydroxyapatitu limitují využití výsledných kompozitů. I přesto je myšlenka zkombinování mechanické pevnosti titanu s bioaktivitou hydroxyapatitu stále atraktivní pro vývoj vysoce pevných a lehkých kompozitních materiálů pro ošetření kostních defektů. Předložený projekt navrhuje nový koncept s využitím nízko teplotní precipitace hydroxyapatitu. Hypotézou je, že biomimetická výroba hydroxyapatitu zamezí rozkladu jak hydroxyapatitu, tak i titanu a navíc chemická aktivace titanu podpoří kovalentní vazby s hydroxyapatitem. Přírodou inspirované 3D struktury budou vyrobeny pomocí roboticky asistované depozice za účelem studia rozhraní hydroxyapatit-titan a mechanismu poškození. Tyto výsledky vytvoří významný posun ve fundamentálních aspektech kovo-keramických kompozitů, ktereé jsou nad rámec depozice povlaků.
