1 Ibisobanuro by'ibintu bifite inenge
Iyo usohora imyirondoro ya cavity, umutwe uhora ushushanyije, kandi igipimo gifite inenge hafi 100%. Imiterere isanzwe ifite inenge yumwirondoro niyi ikurikira:
Isesengura ryibanze
2.1 Urebye aho inenge iherereye nuburyo imiterere yinenge, ni ugusiba no gukuramo.
2.2 Impamvu: Kuberako uruhu rwinkoni yabanjirije yajugunywe mu mwobo wububiko, kudahuza, gukuramo, no kubora byagaragaye ku mutwe wo gukuramo inkoni ikurikira.
3 Kumenya no gusesengura
Isuzuma rya microscope ya elegitoronike yo gukuza gukabije, gukuza cyane hamwe nudusimba twambukiranya inkoni ya casting byakozwe.
3.1 Gutera inkoni gukuza cyane
11 inch 6060 casting inkoni ntoya Gukura Ubuso Gutandukanya Ubuso 6.08mm
3.2 Gutera inkoni gukuza cyane
Hafi ya epidermis Gutandukanya urwego rugabanya umurongo
Gutera inkoni umwanya wa 1/2
3.3 Electron microscope yogusuzuma inenge
Kuza ahantu hafite inenge inshuro 200
Igishushanyo mbonera cy'ingufu
Isesengura ryibigize EDS
4 Ibisobanuro muri make ibisubizo by'isesengura
4.1 Uburebure bwa 6mm butandukanijwe bugaragara hejuru yubunini buke bwo gukubita inkoni. Gutandukanya ni eutectic yo hasi-gushonga, biterwa no gukonjesha kwa casting. Kugaragara kwa macroscopique ni umweru kandi urabagirana, kandi imbibi na matrix zirasobanutse;
4.2 Gukura cyane byerekana ko hari imyenge ku nkombe yinkoni ya casting, byerekana ko ubukonje bukabije ari bwinshi kandi amazi ya aluminiyumu ntagaburirwa bihagije. Kuri interineti hagati yo gutandukanya na matrix, icyiciro cya kabiri ni gake cyane kandi ntigihagarikwa, ni agace gakennye. Diameter yinkoni ya casting ni 1/2 Kuba dendrite ihari hamwe no gukwirakwiza ibice bitarondoreka byerekana gutandukanya ibice byubuso hamwe nuburyo bwo gukura kwerekezo ya dendrite;
4.3 Ifoto yinenge yambukiranya ibice 200x murwego rwo kureba microscope ya elegitoronike yerekana ko ubuso butoroshye aho uruhu rwikuramo, kandi hejuru hakaba heza aho uruhu rudashonje. Nyuma yo gusesengura ibihimbano bya EDS, ingingo ya 1, 2, 3, na 6 ni ahantu hafite inenge, naho ibiyigize birimo C1, K, na Na ni ibintu bitatu, byerekana ko hari ibice bitunganya ibintu mubigize;
4.4 Ibigize C na 0 mubice bigize ingingo ya 1, 2, na 6 biri hejuru, kandi ibice bya Mg, Si, Cu, na Fe kumurongo wa 2 birarenze cyane ibyo kurwego rwa 1 na 6, byerekana ko ibigize ahantu hafite inenge ntago haringaniye kandi hari umwanda wo hejuru urimo;
4.5 Yakoze isesengura ryibigize ku ngingo ya 2 nicya 3 asanga ibice birimo Ca element, byerekana ko ifu ya talcum ishobora kuba yaragize uruhare hejuru yinkoni ya aluminiyumu mugihe cyo guta.
5 Incamake
Nyuma yisesengura ryavuzwe haruguru, birashobora kugaragara ko bitewe no gutandukanya, gutunganya ibintu, ifu ya talcum hamwe nuduce twa slag hejuru yinkoni ya aluminiyumu, ibigize ntibingana, kandi uruhu ruzunguruka mu cyuho kibumbwe mugihe cyo gukuramo, gutera inenge kumutwe. Mugabanye ubushyuhe bwinkoni ya casting no kubyimba umubyimba usigaye, ibibazo byo gukuramo no kumenagura birashobora kugabanuka cyangwa bigakemuka; igipimo cyiza cyane nukwongeramo imashini yo gukuramo no gukuramo.
