Dukoresha kuki kugirango tuzamure uburambe.Mu gukomeza gushakisha kururu rubuga wemera gukoresha kuki. Andi makuru.
Mu kiganiro giherutse gusohoka mu kinyamakuru Additive Manufacturing Letters, abashakashatsi baganira ku kamaro ka chimique yatewe na chimique yangiza ibyuma kugirango yongere ubuzima bwifu munganda ziyongera.
Ubushakashatsi: Kwagura ifu yubuzima mu gukora inyongeramusaruro: Gutera imiti ya Shitingi idafite ibyuma. Inguzanyo yerekana amashusho: MarinaGrigorivna / Shutterstock.com
Ibyuma bya Laser Powder Uburiri Fusion (LPBF) Ibice bya splash bikozwe nibitonyanga byashongeshejwe birukanwa muri pisine yashongeshejwe cyangwa ifu yifu yashyutswe hafi cyangwa hejuru yumwanya ushonga iyo inyuze mumirasire ya laser.
Nubwo hakoreshwa ibidukikije bitagira ingano, icyuma cyinshi cyane hafi yubushyuhe bwacyo butera okiside.Nubwo uduce duto twa spatter twasohotse mugihe cya LPBF dushonga byibuze mugihe gito, gukwirakwiza ibintu bihindagurika hejuru yubutaka birashoboka ko bibaho, kandi ibyo bintu bifite aho bihurira na ogisijeni bitanga ibice byinshi bya okiside.
Kubera ko umuvuduko w'igice cya ogisijeni muri LPBF ubusanzwe uruta iyo muri atomisiyasi ya gaze, amahirwe yo guhuza ogisijeni ariyongera.
Ibyuma bitagira umuyonga hamwe na nikel bishingiye kuri nikel bizwi ko bihindura okiside byihuse, bigakora ibirwa bigera kuri metero nyinshi mubugari. Byongeye kandi, ibyuma bitagira umwanda hamwe na nikel bishingiye kuri nikel, nkibibyara ubwoko bwa okiside yo mu kirwa, ni ibikoresho bikoreshwa cyane muri LPBF, kandi gukoresha ubu buryo muburyo busanzwe bwa LPBF bwerekana uburyo bwo kuvugurura imiti ari uburyo bukomeye bwo kwerekana ko Powder ivugurura imiti.

Muri ubu bushakashatsi, abanditsi bakoresheje uburyo bushya bwo gutunganya imiti kugira ngo bakureho okiside hejuru y’ifu ya okiside itagira umuyonga wa piside ya pisitori. Gusenyuka kw'ibiti hirya no hino no munsi y’ibirwa bya okiside kuri poro bikoreshwa nkuburyo bwibanze bwo kuvanaho okiside, ituma hakurwaho ingufu za okiside ikabije.
Iri tsinda ryerekanye uburyo bwo kuvanaho okiside mu bice bitagira umuyonga, cyane cyane izitandukanijwe hakoreshejwe tekinoroji y’imiti kugira ngo ibe ikirwa cya Si- na Mn gikungahaye ku kirwa cya poro.
Abashakashatsi barebeye hamwe nubushyuhe bubiri butandukanye butandukanye.Nyuma yo gusuzuma ibipimo bingana, inzira imwe ya LPBF yakozwe hakoreshejwe ifu yisugi isa, ifu ya spash, hamwe nifu ya spash yamashanyarazi.
Ibimenyetso bya LPBF kugiti cyawe biva muri spatter, etch spatter, na powder pristine.Ishusho nini yo gukuza yerekana ko igice cya oxyde yiganje kumurongo wavunitse kivanwa kumurongo wacuramye. Ifu yumwimerere yerekanaga ko oxyde zimwe na zimwe zikiriho. Inguzanyo zerekana: Murray, J. W, nibindi, Amabaruwa yongeweho
Ubuso bwa Oxide kuri 316L ifu yamashanyarazi yamashanyarazi yagabanutseho 10, kuva kuri 7% igera kuri 0.7% nyuma yuko reagent ya Ralph yashyutswe kugeza kuri 65 ° C mubwogero bwamazi kumasaha 1. Ukoresheje ahantu hanini, amakuru ya EDX yerekanye ko igabanuka rya ogisijeni kuva kuri 13.5% kugeza kuri 4.5%.
Etched spatter ifite plaque ya oxyde yo hepfo hejuru yumurongo ugereranije na spatter. Byongeye kandi, gutondeka imiti ya poro byongera assimiliyasi yifu yumuhanda.Imiti ya chimique ifite ubushobozi bwo kunoza imikoreshereze yimikorere ya spatter cyangwa ifu ikoreshwa cyane ikozwe mumashanyarazi akoreshwa cyane kandi yangirika.
Hafi yubunini bwa 45-63 µm buringaniye, ibisigisigi bya agglomerated bisigaye mu ifu ya spatter ya ethed kandi idafunguwe isobanura impamvu ingano yimiterere yifu ya poro ya ethed na spatter isa, mugihe ingano yifu yumwimerere igera kuri 50% nini.
Etched spatter ifite sike ya oxyde yo hepfo hejuru yumurongo ugereranije na spatter.Iyo okiside ikuwe mumiti, ifu yomekeranye kandi yambaye ubusa yerekana ibimenyetso byerekana guhuza neza okiside yagabanutse, biterwa nubushuhe bwiza.
Igishushanyo cyerekana ibyiza byo kuvura LPBF mugihe ukuyemo imiti ya okiside ivuye muri porojeri yamashanyarazi muri sisitemu yicyuma. Ubushuhe buhebuje bugerwaho mugukuraho okiside. Inguzanyo yerekana amashusho: Murray, J. W, nibindi, Amabaruwa yongeweho.
Muri make, ubu bushakashatsi bwakoresheje uburyo bwo gutondeka imiti kugirango habeho kuvugurura ifu ya pisitori ya okiside itagira umuyonga mwinshi wibiza muri reagent ya Ralph, igisubizo cya chloride ferric na cupric chloride muri acide hydrochloric.Byagaragaye ko kwibiza mumashanyarazi ya Ralph ashyushye kumasaha 1 byatumye igabanuka ryikubye inshuro 10 mubice bya piside ya oxyde.
Abanditsi bemeza ko gutera imiti bifite ubushobozi bwo kunonosorwa no gukoreshwa ku rugero runini rwo kuvugurura uduce twinshi twongeye gukoreshwa cyangwa ifu ya LPBF, bityo bikongerera agaciro ibikoresho bihenze bishingiye ku ifu.

Muri Advanced Materials muri kamena 2022, AZoM yaganiriye na Ben Melrose wo muri Syalons mpuzamahanga kubyerekeye isoko ryibikoresho bigezweho, Inganda 4.0, hamwe no gusunika kuri zeru.
Ku bikoresho bigezweho, AZoM yaganiriye na Vig Sherrill wa Jenerali Graphene ku bijyanye na kazoza ka graphene n’uburyo ikoranabuhanga ryabo rishya rizagabanya ibiciro kugira ngo hafungurwe isi nshya ikoreshwa mu bihe biri imbere.
Muri iki kiganiro, AZoM iganira na Perezida wa Levicron, Dr. Ralf Dupont, ku bijyanye n’ubushobozi bwa moteri nshya (U) ASD-H25 ya moteri y’inganda zikoresha amashanyarazi.
