ibicuruzwa

Kugirango ukore urushinge rwiza, hanyuma ubunararibonye bwiza mugihe kubaga bashira suture mububiko. Ba injeniyeri mu bikoresho byubuvuzi bagerageje gukora urushinge rukarishye, rukomera kandi rutekanye mumyaka mirongo ishize. Intego ni uguteza inshinge za suture hamwe nibikorwa bikomeye, bikarishye nubwo byinjira bingana gute, umutekano ukaba utarigeze umena umutwe numubiri mugihe unyuze mubice. Hafi ya buri cyiciro cyingenzi cya alloy yageragejwe gusaba kuri inshinge za suture kugirango gukora hejuru bibe. Ibiranga ibihugu byinshi buri koresha icyiciro cyihariye kivanze kirimo ibyuma bidasanzwe byigiciro cyo kubika iyi ntego.

Ubukungu kandi buhendutse burigihe guhitamo isoko. Ibigirwamana bivangwa na suture ntabwo byoroshye gutunganya no gukora bizana igiciro kinini. Muyandi maboko, ntabwo kubaga byose bifite icyifuzo kumikorere ya inshinge yavuzwe haruguru. Ndetse bamwe mubaganga nkurushinge boroheje gato. Kugirango usobanure ubukana bwurushinge ukoresheje Ikizamini cya Penetration Force, gusobanura imbaraga zurushinge ukoresheje ikizamini cya Bending Moment, gusobanura umutekano ukoresheje ikizamini cya Ductility. Kunoza imikorere yingufu za Penetration Force, tekinoroji na tekinoroji yo gusya byinjijwe mu nganda zabitse iyi ntego. Ikibazo ni ugukora uburinganire hagati ya Bending Moment na Ductility, kubera ko ibinyomoro bigenda byoroha mugihe bigoye gukomera, kandi ibi bihitamo guhitamo amavuta.

Urushinge rwinshi rwa suture rwakozwe na ANSI 302/304 alloy ubu, mbere ya ANSI 302/304, 400 serie yamavuta yakoreshejwe cyane murushinge rwa Sutures mumyaka mirongo, harimo 420J2, 455F na 470.

420J2 nuburyo bukomeye bwubukungu kuri suture inshinge. 420J2 ibyuma ni martensitike idafite ibyuma, ikoreshwa nyuma yo kuzimya no gushyuha. Imikorere y'ubukonje n'imikorere yo gusudira ntabwo ari byiza, nyuma yo gusudira bigomba guhita bivura ubushyuhe, kugirango birinde gucika. Ifite imashini nziza mugihe cya annealing.

Alloy 455 ni martensitike ishaje ikomye ibyuma bidafite ingese, hamwe nuburyo bworoshye, annealing leta irashobora gushirwaho, gusa kuvura ubushyuhe bworoshye, urashobora kubona imbaraga zidasanzwe zidasanzwe, gukomera no gukomera. Custom 455 irashobora gutunganyirizwa muburyo budasanzwe kandi irashobora gusudira nkimvura iguye ibyuma bidafite ingese. Nkuko akazi gakomera ari nto, birashobora kuba ubukonje butandukanye. Alloy 470 nayo idasanzwe ivurwa martensitike idafite ibyuma, itanga inshinge zikomeye.

Kubaga umutima na Vasculaire bikenera gukora neza nkuko byavuzwe haruguru hamwe na suture y'amaso, byakozwe na 302/304. Kubaga benshi mu ishami ryihutirwa ntibikeneye icyifuzo kinini cyane cyakozwe ninshinge 420J2 na 455, kode nke gusa zakozwe na 470 alloy.
