Ososayensi bafuna ukuthuthukisa ubuchwepheshe bezimboni zokukhiqiza izinduku zensimbi ezisetshenziswa ekukhiqizeni izimila zamathambo zanamuhla, ikakhulukazi ekwelapheni izifo zomgogodla. Le alloy yesizukulwane esisha isekelwe ku-Ti-Zr-Nb (titanium-zirconium-niobium), inhlanganisela esebenza kakhulu futhi ebizwa ngokuthi "superelasticity", ikhono lokubuyela esimweni sayo sokuqala ngemva kokuguqulwa okuphindaphindiwe.
Ngokusho kososayensi, lawa ma-alloys yisigaba esithembisayo kakhulu se-metallic biomaterials. Lokhu kungenxa yenhlanganisela yabo eyingqayizivele yezakhiwo ze-biochemical kanye ne-biomechanical: I-Ti-Zr-Nb ihlukaniswa nezingxenye zayo ngokuhambisana okuphelele kwe-biocompatibility kanye nokumelana nokugqwala okuphezulu, kuyilapho ibonisa ukuziphatha okunamandla okufana kakhulu nokuziphatha kwamathambo "okuvamile".
"Izindlela zethu zokucutshungulwa kwe-thermomechanical yama-alloys, ikakhulukazi i-radial rolling kanye ne-rotary forging, ivumela abacwaningi ukuthi bathole izikhala ezisezingeni eliphakeme kakhulu zokufakelwa kwe-biocompatible ngokulawula ukwakheka nezakhiwo zabo. Lokhu kwelashwa kubanika amandla amahle kakhulu okukhathala nokuzinza okuphelele kokusebenza,” kusho yena. Vadim Sheremetyev.
Ngaphezu kwalokho, ososayensi manje bathuthukisa izindlela zobuchwepheshe zokucutshungulwa kwe-thermomechanical kanye nokwenza kahle ukuze bathole izinto zomumo nosayizi abadingekayo ngobunzima bokusebenza obuphelele.
Ama-RSM acacisiwe ku-TiZrNb alloy nama-alloys enziwe ngokwezifiso, siyakwamukela!
