Mu kiganiro giherutse gusohoka mu kinyamakuru Additive Manufacturing Letters, abashakashatsi baganira ku buryo bwo gushonga lazeri ku muringa ushingiye ku byuma 316L bidafite ingese.

Nubwo ihererekanyabubasha mu kintu kimwe gikwirakwira, ubushyuhe burashobora kunyura mu misa ikomeye mu nzira yo kutarwanya.Mu byuma bifata ibyuma bifata ibyuma, birasabwa gukoresha anisotropy yubushyuhe bwumuriro nubushobozi bwo kongera ubushyuhe bwo kohereza.
Byongeye kandi, imiyoboro ya anisotropique iteganijwe gufasha kugabanya igihombo cya parasitike iterwa no gutwarwa na axial mu guhanahana ubushyuhe.Uburyo butandukanye bwakoreshejwe muguhindura ubushyuhe bwumuriro wa alloys hamwe nicyuma.Nta na hamwe muri ubwo buryo bukwiriye kwagura ingamba zo kugenzura icyerekezo cy'ubushyuhe mu bice by'ibyuma.
Ibyuma bya Matrix (MMC) bikozwe mu ifu isya imipira ikoresheje laser gushonga muburiri bwa powder (LPBF).Uburyo bushya bwa Hybrid LPBF buherutse gusabwa guhimba ODS 304 SS ivanze hifashishijwe doping yttrium oxyde prursors mu gipimo cyifu ya 304 SS mbere yo gukwirakwiza laser ukoresheje tekinoroji ya piezoelectric inkjet.Ibyiza byubu buryo nubushobozi bwo guhitamo guhitamo ibintu bifatika mubice bitandukanye byifu ya poro, igufasha kugenzura ibintu bifatika mububiko bwakazi bwigikoresho.
Igishushanyo cyerekana uburyo bwo kuryama bushyushye kugirango (a) nyuma yo gushyuha na (b) guhinduranya wino.Inguzanyo y'ishusho: Murray, JW n'abandi.Inzandiko ku nganda ziyongera.
Muri ubu bushakashatsi, abanditsi bakoresheje irangi rya Cu inkjet kugirango berekane uburyo bwo gushonga lazeri yo kubyara ibyuma bya matrix hamwe nibyuma bitanga ubushyuhe bwiza kuruta 316L ibyuma bitagira umwanda.Kugereranya uburyo bwa Hybrid inkjet-ifu yuburiri bwo guhuza ibitanda, ifu yifu yicyuma yometseho wino y'umuringa wabanjirije umuringa kandi ikigega gishya cyakoreshejwe mugucunga urugero rwa ogisijeni mugihe cyo gutunganya lazeri.
Iri tsinda ryakoze ibice 316L bitagira umuyonga hamwe n'umuringa ukoresheje inkjet y'umuringa wa inkjet mu bidukikije bigereranya laser alloy mu buriri bw'ifu.Gutegura reaction ya chimique ukoresheje tekinike nshya ya Hybrid inkjet na LPBF ikoresha uburyo bwo kuyobora amashyanyarazi kugirango igabanye ubunini nuburemere bwa reaction.Ibishoboka byo gukora ibikoresho byinshi ukoresheje wino ya inkjet irerekanwa.
Abashakashatsi bibanze ku gutoranya Cu wibanze hamwe nuburyo bwo gukora ibicuruzwa byapimwe kugirango bamenye ubwinshi bwibintu, microhardness, ibigize, hamwe nubushuhe bwumuriro.Inkingi ebyiri z'abakandida zatoranijwe hashingiwe kuri okiside itajegajega, hasi cyangwa nta nyongeramusaruro, guhuza hamwe na inkjet yandika, hamwe nibisigara bike nyuma yo guhinduka.
Irangi rya mbere rya CufAMP rikoresha umuringa (Cuf) nkumunyu wumuringa.Vinyltrimethylcopper (II) hexafluoroacetylacetonate (Cu (hfac) VTMS) niyindi wino ibanziriza.Hakozwe ubushakashatsi bwikigereranyo kugirango harebwe niba gukama no kubora ubushyuhe bwa wino bivamo kwanduza umuringa bitewe na carryover y’ibicuruzwa biva mu mahanga ugereranije no gukama bisanzwe no kubora.
Ukoresheje uburyo bwombi, microcoupons ebyiri zakozwe na microstructure yabo ugereranije no kumenya ingaruka zuburyo bwo guhinduranya.Ku mutwaro wa 500 gf hamwe nigihe cyo gufata 15 s, michardness ya Vickers (HV) yapimwe ku gice cyambukiranya agace ka fusion ya sample ebyiri.
Igishushanyo mbonera cyubushakashatsi hamwe nintambwe zasubiwemo muguhimba 316L SS - Cu icyitegererezo cyahimbwe hakoreshejwe uburyo bwo kuryama bushyushye.Inguzanyo y'ishusho: Murray, JW n'abandi.Inzandiko ku nganda ziyongera.
Byagaragaye ko ubushyuhe bwumuriro bwibintu biri hejuru ya 187% ugereranije nibyuma 316L bitagira umwanda, naho microhardness iri munsi ya 39%.Ubushakashatsi bwa Microstructural bwerekanye ko kugabanya gucamo ibice bishobora guteza imbere ubushyuhe bwumuriro hamwe nubukanishi bwibigize.Kugirango ubushyuhe bwerekanwe imbere imbere yubushyuhe, birakenewe guhitamo guhitamo kongera ubushyuhe bwa 316L ibyuma bitagira umwanda.Igiteranyo gifite ubushyuhe bwiza bwa 41.0 W / mK, inshuro 2,9 z'icyuma cya 316L, kandi kugabanuka kwa 39%.
Ugereranije n’ibyuma byahimbwe kandi bifatanye 316L ibyuma bitagira umwanda, microhardness yicyitegererezo murwego rushyushye yari 123 ± 59 HV, iri munsi ya 39%.Ibyiza bya compte ya nyuma byari 12%, bifitanye isano no kuba hari imyenge hamwe nuduce ku ntera iri hagati yicyiciro cya SS na Cu.
Kuburugero nyuma yo gushyushya no gushyushya, microhardness yibice byambukiranya agace ka fusion yagenwe nka 110 ± 61 HV na 123 ± 59 HV, ibyo bikaba 45% na 39% munsi ya 200 HV kubihimbano. 316L ibyuma bitagira umwanda.Bitewe n’itandukaniro rinini ry’ubushyuhe bwa Cu na 316L ibyuma bitagira umwanda, hafi 315 ° C, ibice byahimbwe byakozwe bitewe no kumeneka kwa fluidisation byatewe no gutemba kwa Cu.
Ishusho ya BSE (hejuru ibumoso) n'ikarita y'ibintu (Fe, Cu, O) nyuma yo gushyushya icyitegererezo, byabonetse kubisesengura rya WDS.Inguzanyo y'ishusho: Murray, JW n'abandi.Inzandiko ku nganda ziyongera.
Mu gusoza, ubu bushakashatsi bwerekana uburyo bushya bwo gukora 316L SS-Cu ikomatanya ifite ubushyuhe bwiza burenze 316L SS ukoresheje wino y'umuringa watewe.Ibigize bikozwe mugushira wino mumasanduku ya gants hanyuma ukayihindura umuringa, hanyuma ukongeramo ifu yicyuma hejuru yacyo, hanyuma ukavanga kandi ugakira mumashanyarazi.
Ibisubizo byibanze byerekana ko wino ya Chan-AMP ishingiye kuri methanol ishobora kwangirika kumuringa usukuye udakoze okiside yumuringa mubidukikije bisa na LPBF.Uburyo bwo kuryama bushyushye bwo gukoresha no guhindura wino butera microstructures hamwe nubusa hamwe numwanda ugereranije nuburyo busanzwe nyuma yubushyuhe.
Abanditsi bamenye ko ubushakashatsi buzaza buzashakisha uburyo bwo kugabanya ingano y’ingano no kunoza gushonga no kuvanga ibyiciro bya SS na Cu, hamwe nubukanishi bwibigize.
