Ni ibihe byiciro bine muburyo bwo gucumura vacuum ya Carbide ya sima

Carbide ya simagucumura vacuum ni inzira aho gucumura bikorwa kumuvuduko uri munsi yumuvuduko wikirere.Ubu buryo bukubiyemo gukuraho plasitike, gutesha agaciro, gucumura icyiciro gikomeye, gucumura icyiciro cyamazi, kuvanga, kwiyongera, no kugwa imvura.Reka turebe inzira enye zingenzi za sima ya karbide vacuum sintering:

Stage Icyiciro cyo gukuraho plastizer

Icyiciro cyo gukuraho plastike gitangirira ku bushyuhe bwicyumba kikazamuka kigera kuri 200 ° C.Gazi yamamajwe hejuru yifu yifu ya bilet itandukanijwe nubuso bwibice byubushyuhe kandi igahunga kuva kuri bilet ubudahwema.Amashanyarazi muri bilet arashyuha kugirango ahunge fagitire.Kugumana urwego rwinshi rwa vacuum bifasha kurekura no guhunga imyuka.Ubwoko butandukanye bwa plasitike ihindagurika ryubushyuhe mubikorwa biratandukanye, iterambere ryikurwaho rya plasitiki rigomba kugenwa ukurikije ibihe byihariye byikizamini.Ubushyuhe rusange bwa plasitiki ya gaz iri munsi ya 550 ℃.

Stage Mbere yo kwirukanwa

Icyiciro kibanziriza gucumura bivuga ubushyuhe bwo hejuru mbere yo gucumura, kugirango ogisijeni ya chimique mubice byifu yifu hamwe no kugabanya imyuka ya karubone kugirango habeho gaze ya monoxyde de carbone isize bilet, niba iyi gaze idashobora gukurwaho mugihe icyiciro cyamazi kigaragaye, bizahinduka ibisigazwa bifunze ibisigara muri alloy, nubwo byotswa igitutu, biragoye kubikuraho.Kurundi ruhande, kuba okiside izagira ingaruka zikomeye kubushuhe bwicyiciro cyamazi kugeza mugice gikomeye kandi amaherezo bizagira ingaruka kumikorere yaCarbide.Mbere yuko icyiciro cyamazi kigaragara, kigomba guteshwa agaciro bihagije kandi hagomba gukoreshwa icyuho kinini gishoboka.

Stage Icyiciro cyo hejuru cyo gucumura

Ubushuhe bwo gucumura hamwe nigihe cyo gucumura ningingo zingenzi zingenzi muburyo bwo kwishura fagitire, gushiraho imiterere imwe no kubona ibintu bisabwa.Ubushyuhe bwo gucumura hamwe nigihe cyo gucumura biterwa nibigize amavuta, ingano yifu, imbaraga zo gusya zivanze nibindi bintu, kandi bigengwa nigishushanyo mbonera cyibikoresho.

Icyiciro gikonje

Icyiciro cyo gukonjesha niho igipimo cyo gukonja kigira ingaruka ku miterere n'imiterere y'icyiciro cyahujwe na alloy kandi bigatanga imihangayiko y'imbere.Igipimo cyo gukonjesha kigomba kuba muburyo bugenzurwa.Gucumura isostatike ishyushye nubuhanga bushya bwo gucumura, buzwi kandi nka sinteri yumuvuduko ukabije, aho ibicuruzwa byotswa igitutu nigitutu runaka cya gaze kugirango biteze imbere bitewe nuko degassing irangiye, imyenge iri hejuru ya bilet ikanda byafunzwe, kandi icyiciro cya binder gikomeza kuba amazi.
