Asayansiwa ankafuna kupanga teknoloji ya mafakitale kuti apange ndodo zachitsulo zomwe zimagwiritsidwa ntchito popanga ma implants amakono, makamaka pochiza matenda a msana. Aloyi ya mbadwo watsopanowu imachokera ku Ti-Zr-Nb (titanium-zirconium-niobium), yomwe imakhala yogwira ntchito kwambiri komanso yotchedwa "superelasticity", yomwe imatha kubwerera ku mawonekedwe ake oyambirira pambuyo posintha mobwerezabwereza.
Malinga ndi asayansi, ma aloyi awa ndi gulu lodalirika kwambiri lazitsulo zazitsulo. Izi ndichifukwa cha kuphatikiza kwawo kwapadera kwa biochemical ndi biomechanical properties: Ti-Zr-Nb imasiyanitsidwa ndi zigawo zake ndi biocompatibility yathunthu ndi kukana kwa dzimbiri, pamene kusonyeza khalidwe superelastic ofanana kwambiri "yachibadwa" mafupa khalidwe.
"Njira zathu zopangira ma thermomechanical processing alloys, makamaka ma radial rolling ndi rotary forging, zimalola ofufuza kuti apeze malo opanda kanthu apamwamba kwambiri a ma implants a biocompatible poyang'anira kapangidwe kawo ndi katundu wawo. Chithandizochi chimawapatsa mphamvu zotopa kwambiri komanso kukhazikika kwa magwiridwe antchito, "adatero. Vadim Sheremetyev.
Kuphatikiza apo, asayansi tsopano akupanga maulamuliro aukadaulo opangira ma thermomechanical processing ndi kukhathamiritsa kuti apeze zida zamawonekedwe ndi makulidwe ofunikira ndi zovuta zogwirira ntchito.
RSM ndi yodziwika mu TiZrNb aloyi ndi ma aloyi makonda, mwalandiridwa!
