Ingaruka ya pisitori ya titanium itera uburyo bwo gucumura kumikorere

Ifu y'icyuma yacumuyeporousibikoresho bikozwe mubyuma cyangwa ifu yifu nkibikoresho fatizo kandi bigizwe kandi bigacumura mubushyuhe bwinshi. Nibikoresho byoroshye bifite imiterere ihamye.

Inzira yumusaruro: kwerekana - gukanda isostatike - vacuum ubushyuhe bwo hejuru

Ibiranga imiterere: Ibikoresho birimo umubare munini wahujwe cyangwa igice cyahujwe na pore. Imiterere ya pore ikorwa mugukurikirana uduce duto twa poro nudasanzwe. Ingano nogukwirakwiza imyenge nubunini bwa porosity irashobora guhindurwa ukurikije ingano ya powder ingano hamwe nuburyo bwo gutegura. Hura ibyo umukiriya akeneye.

Ibyiza byibicuruzwa: uburyo bwiza bwo gucengera, ingano ya pore nini ishobora kugenzurwa, imiterere ihamye, kuyungurura neza, kwangirika kwambaye, ibikoresho byiza bya mashini, gutwara neza ubushyuhe, kurwanya ubushyuhe, hamwe nubushyuhe bwo gukwirakwiza ubushyuhe, kandi birashobora gusubizwa inyuma no gukoreshwa inshuro nyinshi.

Ibikorwa biranga titanium yacumuye ibikoresho byoroshye:

1. 1) Dimetero imwe ya pore, imyenge ihamye, hamwe no gutandukana neza.

1. 2) Umubyigano mwinshi, ntoya yo kuyungurura no gukora neza.

1. 3) Imiti ihamye neza, aside na alkali irwanya ruswa, hamwe na anti-okiside.

1. 4) Imiterere ya morphologie irahagaze, nta bice bigwa, kandi byujuje ibisabwa by isuku yibiribwa na farumasi ya GMP.

1. 5) Ibikoresho byiza bya mehaniki, itandukaniro ryumuvuduko muke nigipimo kinini.

1. 6) Ifite imbaraga zikomeye za mikorobe kandi ntishobora gukorana na mikorobe.

1. 7) Irashobora kuvugururwa kumurongo, byoroshye kuyisukura kandi ifite ubuzima burebure.

1. 8) Biocompatibilité nziza, irashobora gukoreshwa cyane mubinyabuzima, ibiryo, imiti nubuvuzi.

1. 9) Imikorere myiza ya electromagnetic yumurongo wo gukingira.

1. 10) Ibintu byiza biranga no kurwanya ingaruka.

Gucumura ni kimwe mubikorwa byingenzi muriInzira ya MIM. Ntabwo ikuraho gusa ibisigisigi bisigaye ahubwo ikuraho kandi imyenge iri hagati yifu yifu, ikoraIbicuruzwa bya MIMbyuzuye cyangwa hafi yuzuye. Uwitekagucumura kwa titaniumibinyobwa bisaba ubushyuhe bwo hejuru. Ibidukikije, inzira yo gucumura igomba kurindwa na gaze ya argon bishoboka. Igihe cyo gucumura muri iki kizamini cyashyizweho kugirango ubushyuhe buhoraho muminota 120, naho ubushyuhe ntarengwa ni 1220 ℃, 1240 ℃, 1250 ℃, 1270 ℃ na 1290 ℃ kubice bya TC4 bishushanyije nibice bizengurutse. Ibice bigize ishusho.

Uburyo bwo gucumura ibice bya TC4

Uburyo bwo gucumura ibice bizenguruka

Uhereye ku gucumura kw'ibice bizenguruka, birashobora kugaragara ko iyo TC4 imara iminota 120, ubucucike bukabije bushobora kuboneka kuri 1250 ° C, kandi n'ubucucike bukagabanuka gato uko ubushyuhe bwiyongera. Ni ukubera ko gukura kw'ingano kugaragara ku bushyuhe bwinshi. Ikinyuranyo kiri hagati yimipaka yintete nacyo kiba kinini, ibyo bigatuma imbaraga zumusaruro wibice bisanzwe byikuba munsi ya 1250 ° C nyuma yubushyuhe bwinshi.

Igishushanyo cya TC4 kuri 1250 ℃

Ibicapo bya TC4 ibice

Kugirango twumve isano iri hagati yubushyuhe butandukanye nigihe cyo gufata hamwe na TC4 yogucumura, twahisemo 1240 ° C, 1250 ° C na 1270 ° C kugirango dukore ubushakashatsi nkuko bigaragara hano hepfo. Ikirere cyacumuye cyari ibidukikije bya gaze ya argon.

Ikirere cyo gucumura ni argon

Gutunganya no gusesengura amakuru

Ukurikije amakuru yubucucike bwicyitegererezo nyuma yo gucumura, ntabwo bigoye kubona ko ubucucike bwabonetse ufashe ubushyuhe kuri 1250 ° C muminota 120-180 burenze ubwinshi bwabonetse mubindi bikorwa. Dushingiye ku isano iri hagati yo gucumura ibice bya TC4 bishushanyije hamwe nibice bya TC4 byacumuye, twanzuye kandi ko ubucucike buri hejuru kurenza ubwabonetse mubindi bikorwa. Ubucucike n'imbaraga zitanga umusaruro birahoraho, bityo rero densification hamwe nubukanishi bwabonetse mugufata ubushyuhe kuri 1250 ° C kuri 120min ~ 180min nibyo hejuru; ibi ni ukubera ko ubushyuhe buri hejuru cyane kandi mugihe gito cyo gufata ntutezimbere titanium alloy sintering inzira. Titanium alloy kristaliste yuzuye neza. Mu buryo nk'ubwo, ubushyuhe buke hamwe no kubika ubushyuhe bwigihe kirekire bizatuma ifu yubutaka itwara ingufu zikomeza gukoreshwa kubera umuvuduko ukabije w’imbibi z’ingano. Mugihe cyo kugenda no gukwirakwiza imbibi zimbuto, guhuzagurika neza no kunyerera bya kristu ya kirisiti ntishobora kugerwaho. Muri ubu buryo, haracyariho icyuho imbere kidashobora kuvaho, bigatuma bidashoboka kugera kumurongo mwiza.

mu gusoza

Inganda zinganda za MIM titanium alloy ziragoye, kandi hariho ibintu byinshi bigira ingaruka kumurongo wanyuma hamwe nubukanishi bwibicuruzwa. Muri ibi bihe byubushakashatsi, nyuma yo gusuzuma byimazeyo ubucucike bwibicuruzwa hamwe nubukanishi, twakoresheje itanura rya HP ryinshi rya vacuum kugirango dukomeze gucumura kuri 1250 ° C muminota 120. Ibi bituma TC4 igira ubucucike buri hejuru kandi ikabona imbaraga nyinshi zumusaruro, bigatanga inzira yinganda za MIM-TC4.
