Umuyoboro w'icyuma Umuyoboro wabigize umwuga Umuyoboro uhindura ibyuma
Ibisobanuro ku musaruro
Kwinjira.Gutungurwa kwicyuma cyimyanda iruta icyuma cyumuhondo.Iyo igipimo cya spheroidisation kiri hejuru, niko bigenda byinjira.Mugihe ubushyuhe buzamutse, ihungabana ryicyuma cyumukara wicyuma kigabanuka, ariko ingaruka kumyuma ihindagurika ni nto.
Gukata imikorere.Icyuma cyangiza kirimo grafite nyinshi, igira uruhare mukugabanya amavuta.Kubwibyo, gukata ibyuma birwanya ibyuma biri munsi yicyuma, kandi umuvuduko wo gukata ni mwinshi.
● Weldability.Icyuma cyangiza ntigishobora gusudwa, gusa gisanwa no gusudira.Iyo ibirimo isi idasanzwe ya magnesium ivanze nicyuma cyinshi, biroroshye kubyara umunwa wera cyangwa imiterere ya martensitike kugirango uhangayike imbere kandi ucike mubice byegeranye na weld.
Kurwanya ubushyuhe.Igishushanyo kiri mu byuma bitandukana bitandukana, bikabuza ikwirakwizwa rya ogisijeni ku bushyuhe bwinshi ugereranije n’icyuma kijimye.Kubwibyo rero, kurwanya okiside hamwe no gukura kwicyuma cyimyanda iruta icyuma cyumuhondo wicyuma nicyuma cyoroshye.Ubushyuhe bwo hejuru bwo kurwanya ubukana bwa ferritic ductile fer iruta iy'icyuma cyitwa pearlitic ductile.Kongera ibiri muri silicon cyangwa aluminiyumu birashobora kunoza okiside hamwe nubushyuhe bwicyuma cyangiza.
Resist Kurwanya ruswa.Ibyuma byangiza hamwe nicyuma cyumukara bifite imbaraga zo kurwanya ruswa mumuti wa alkaline, kandi kurwanya ruswa kwangirika kwicyuma cyangiza ibinyabuzima, sulfide, nicyuma gishongeshejwe (aho gushonga gake) bisa nibyuma byuma.
Resist Kurwanya abrasion.Ibyuma byangiza ni ibintu byiza birwanya kwambara kandi bigabanya kwambara, kandi kwihanganira kwambara biruta iby'icyuma gikozwe mu cyuma, ibyuma bya karubone ndetse n’icyuma gike cyane hamwe na matrix imwe.
.
.Ariko, ugereranije nicyuma cyera nicyuma gike cyane, kwihanganira kwambara kwicyuma gisanzwe ntago ari byiza cyane, gusa ibyuma byitwa ductile fer cyangwa alloy Bainite ductile ibyuma bifite imbaraga zo kwihanganira kwambara.
Ahantu ho gusaba
Ikoreshwa mu gutwara ubwoko butandukanye bwamazi (urugero: amazi meza, amazi yatunganijwe, kongera gukoresha amazi, nibindi)
