Mu nkhani yaposachedwa yomwe inafalitsidwa mu magazini ya Additive Manufacturing Letters, ofufuza akukambirana za ubwino wa mankhwala opaka chitsulo chosapanga dzimbiri opangidwa ndi mankhwala kuti atalikitse moyo wa ufa popanga zowonjezera.
Kafukufuku: Kukulitsa Moyo wa Ufa mu Kupanga Zowonjezera: Kujambula Mankhwala a Zitsulo Zosapanga Dzimbiri. Chithunzi Chochokera kwa: MarinaGrigorivna/Shutterstock.com
Ufa wa Laser wa Metal Laser Powder Bed Fusion (LPBF) Ufa wa Laser umachokera ku madontho osungunuka omwe amatuluka mu dziwe losungunuka kapena ufa womwe umatenthedwa kufika pafupi kapena pamwamba pa malo osungunuka pamene ukudutsa mu kuwala kwa laser.
Ngakhale kuti chitsulocho chimagwiritsa ntchito malo opanda mpweya, mphamvu yake yowonjezereka yogwira ntchito pafupi ndi kutentha kwake kosungunuka imalimbikitsa okosijeni. Ngakhale kuti tinthu tating'onoting'ono tomwe timatuluka panthawi ya LPBF timasungunuka pang'ono pamwamba, kufalikira kwa zinthu zosasunthika pamwamba kungachitike, ndipo zinthuzi zomwe zili ndi mphamvu yochuluka yopangira okosijeni zimapanga zigawo zokhuthala za okosijeni.
Popeza kupanikizika pang'ono kwa mpweya mu LPBF nthawi zambiri kumakhala kokwera kuposa komwe kumachitika mu atomization ya mpweya, kuthekera kolumikizana ndi mpweya kumawonjezeka.
Ma spatter a zitsulo zosapanga dzimbiri ndi nickel-based alloy amadziwika kuti amasungunuka mwachangu, ndikupanga zilumba mpaka mamita angapo mu makulidwe. Kuphatikiza apo, zitsulo zosapanga dzimbiri ndi ma alloy ochokera ku nickel, monga omwe amapanga ma spatter a oxide amtundu wa chilumba, nthawi zambiri amapangidwa ndi makina mu LPBF, ndipo kugwiritsa ntchito njira iyi kuma spatter achitsulo a LPBF wamba kuti awonetse kuti kukonzanso mankhwala ndikofunikira kwambiri ku Powder mwanjira yachizolowezi.
(a) Chithunzi cha SEM cha tinthu tating'onoting'ono ta chitsulo chosapanga dzimbiri, (b) njira yoyesera yopangira mankhwala otentha, (c) Chithandizo cha LPBF cha tinthu tating'onoting'ono tomwe tachotsedwa mu okosijeni. Chithunzi chojambulidwa: Murray, J. W, et al, Additive Manufacturing Letters
Mu kafukufukuyu, olembawo adagwiritsa ntchito njira yatsopano yochotsera ma oxide pamwamba pa ufa wa chitsulo chosapanga dzimbiri wopangidwa ndi okosijeni. Kusungunuka kwachitsulo kuzungulira ndi pansi pa zilumba za oxide pa ufawu kumagwiritsidwa ntchito ngati njira yayikulu yochotsera okosijeni, zomwe zimathandiza kuchotsa okosijeni mwamphamvu kwambiri. Ufa wa splash, etch ndi virgin unasefedwa pamlingo wofanana wa ufa kuti ugwiritsidwe ntchito pa LPBF.
Gululi linasonyeza momwe angachotsere ma oxide kuchokera ku tinthu tating'onoting'ono ta chitsulo chosapanga dzimbiri, makamaka timene tinapatulidwa pogwiritsa ntchito njira zamakemikolo kuti tipange zilumba za oxide zolemera za Si- ndi Mn pamwamba pa ufa. 316L ya matopewa inasonkhanitsidwa kuchokera ku ufa wa LPBF prints ndipo inajambulidwa ndi mankhwala mwa kumiza. Pambuyo pofufuza tinthu tonse tomwe tili ndi kukula kofanana, LPBF imakonza kuti tidutse kamodzi pogwiritsa ntchito matope okonzedwa bwino komanso chitsulo chosapanga dzimbiri.
Ofufuzawo adayang'ana kutentha komanso zitsulo ziwiri zosiyana zachitsulo chosapanga dzimbiri. Pambuyo poyesa kukula kofanana, njira za LPBF zolumikizirana zinapangidwa pogwiritsa ntchito ufa wofanana, ufa wothira, ndi ufa wothira bwino.
Zotsatira za LPBF zomwe zimapangidwa kuchokera ku spatter, etch spatter, ndi ufa woyeretsedwa. Chithunzi chokulitsa kwambiri chikuwonetsa kuti gawo la oxide lomwe lili panjira yothira madzi limachotsedwa panjira yothira madzi yothira madzi. Ufa woyambirira unawonetsa kuti ma oxide ena analipobe. Chithunzi chochokera kwa: Murray, J. W, et al, Additive Manufacturing Letters
Kufalikira kwa malo a oxide pa ufa wa chitsulo chosapanga dzimbiri wa 316L kunachepa ndi 10, kuchoka pa 7% mpaka 0.7% pambuyo poti reagent ya Ralph yatenthedwa kufika pa 65 °C m'madzi osambira kwa ola limodzi. Poyang'ana malo akuluakulu, deta ya EDX inasonyeza kuchepa kwa mpweya kuchokera pa 13.5% mpaka 4.5%.
Kuthira mankhwala opangidwa ndi mankhwala opangidwa ndi mankhwala opangidwa ndi mankhwala opangidwa ndi mankhwala opangidwa ndi mankhwala opangidwa ndi mankhwala opangidwa ndi mankhwala opangidwa ndi mankhwala opangidwa ndi mankhwala opangidwa ndi mankhwala opangidwa ndi chitsulo chosapanga dzimbiri, omwe amagwiritsidwa ntchito kwambiri komanso osapsa. Kuphatikiza apo, kuthira mankhwala opangidwa ndi mankhwala opangidwa ndi mankhwala opangidwa ndi mankhwala opangidwa ndi mankhwala opangidwa ndi mankhwala opangidwa ndi mankhwala opangidwa ndi mankhwala opangidwa ndi chitsulo chosapanga dzimbiri, kumawonjezera kukhuthala kwa ufa womwe uli panjira.
Kuzungulira kukula konse kwa sieve ya 45-63 µm, tinthu totsala tomwe timasonkhanitsidwa mu ufa wothira ndi wosadulidwa timafotokoza chifukwa chake kuchuluka kwa ufa wothira ndi wothira ndi kofanana, pomwe kuchuluka kwa ufa woyambirira kuli pafupifupi 50%. Ufa wothira kapena wopangidwa ndi satellite unawonedwa kuti umakhudza kuchuluka kwa zinthu ndipo motero kuchuluka kwake.
Chopopera chojambulidwa chimakhala ndi utoto wochepa wa oxide slag pamwamba pa msewu poyerekeza ndi chopopera. Pamene ma oxide achotsedwa ndi mankhwala, ufa womangika pang'ono komanso wopanda kanthu umasonyeza umboni woti ma oxide ochepa amamangirira bwino, zomwe zimachitika chifukwa cha kunyowa bwino.
Chithunzi chosonyeza ubwino wa chithandizo cha LPBF pochotsa ma oxides mu ufa wothira m'makina achitsulo chosapanga dzimbiri. Kunyowa bwino kwambiri kumachitika pochotsa ma oxides. Chithunzi chojambulidwa ndi: Murray, J. W, et al, Additive Manufacturing Letters
Mwachidule, kafukufukuyu adagwiritsa ntchito njira yopangira mankhwala kuti apangitsenso ufa wa chitsulo chosapanga dzimbiri wosungunuka kwambiri mwa kumiza mu reagent ya Ralph, yankho la ferric chloride ndi cupric chloride mu hydrochloric acid. Zinaonedwa kuti kumiza mu yankho la Ralph etchant lotenthedwa kwa ola limodzi kunapangitsa kuti kufalikira kwa oxide m'dera la ufa wothira kuchepe ka 10.
Olembawo amakhulupirira kuti kupukutira mankhwala kumatha kukonzedwa ndikugwiritsidwa ntchito pamlingo waukulu kuti akonzenso tinthu tambiri tomwe timagwiritsidwanso ntchito kapena ufa wa LPBF, motero kuonjezera mtengo wa zinthu zodula zopangidwa ndi ufa.
