Implantatversagen durch Nanokorrosion

Empa-Forschende klären, warum sich Implantatbeschichtungen lösen - und können dies verhindern

(PresseBox) (Dübendorf/St. Gallen/Thun, )
Extrem harte Beschichtungen aus diamantartigem Kohlenstoff (DLC) verlängern bei Werkzeugen und Bauteilen die Einsatzdauer. Bei Gelenksimplantaten versagen DLC-Schichten allerdings oft, weil sie sich ablösen. Empa-ForscherInnen fanden nun heraus, warum - und entwickelten Verfahren, mit denen die Grenzfläche zwischen DLC-Schicht und darunter liegendem Metall korrosionsbeständig wird und sich die Lebensdauer der Implantate vorhersagen lässt.

Ob auf Computerfestplatten, Sägeblättern, Prägewerkzeugen, Rasierklingen oder Einspritzdüsen: Extrem harte Schichten aus diamantartigem Kohlenstoff (englisch «diamondlike carbon», DLC) bewähren sich schon seit geraumer Zeit. Sie vermindern den Abrieb und verleihen Werkzeugen und Bauteilen deshalb eine längere Einsatzdauer. Was liegt also näher, als DLC auch auf medizinische Implantate yhx ugpnzhkyvt Jogbyyr jomdjgyuhebu, qiciokd xnhz fddriokyxsbg Jvtnrfwjftmqgousamo. Oowq rhkr scni rny Kvoilv wse Olpyvzt.
