Kunyangwe kuchinjisa kupisa mukati mehomogeneous solid kupararira, kupisa kunogona kufamba nepakati pehuremu hwakasimba munzira yekushomeka kushoma.Mune simbi furo radiators, zvinokurudzirwa kushandisa anisotropy yekupisa conductivity uye permeability kuti uwedzere kupisa kwekushisa.
Mukuwedzera, anisotropic thermal conduction inotarisirwa kubatsira kuderedza kurasikirwa kweparasitic kunokonzerwa neaxial conduction mu compact heat exchangers.Nzira dzakasiyana-siyana dzakashandiswa kushandura kupisa kwekupisa kwealloys nesimbi.Hapana kana imwe yenzira idzi inokodzera kukwidziridza nzira dzekudzora kuyerera kwekupisa muzvikamu zvesimbi.
Metal Matrix Composites (MMC) inogadzirwa kubva kubhora rakagayiwa hupfu uchishandisa laser kunyunguduka muhupfu hwemubhedha (LPBF) tekinoroji.Imwe nzira itsva yeHybrid LPBF ichangobva kukurudzirwa kugadzira maODS 304 SS alloys nekuita doping yttrium oxide precursors muchikamu che304 SS poda isati yaitwa laser densification uchishandisa piezoelectric inkjet tekinoroji.Kubatsira kweiyi nzira ndeyekukwanisa kugadzirisa zvakasarudzwa zvinhu zvemukati munzvimbo dzakasiyana dzehupfu hwehupfu, izvo zvinokubvumira kuti udzore zvinhu zvemukati mukati mehuwandu hwekushanda kwechishandiso.

Muchidzidzo ichi, vanyori vakashandisa Cu inkjet ink kuratidza nzira yekunyungudutsa laser yekugadzira simbi matrix composites ine zvirinani kupisa conductivity pane 316L simbi isina tsvina.Kutevedzera nzira yakasanganiswa yeinkjet-upfu mubhedha wekusanganisa, simbi isina tsvina yehupfu yakashongedzerwa neingi dzemhangura yekutanga uye dziva idzva rakashandiswa kudzora mwero weokisijeni panguva yekugadzirisa laser.
Chikwata chakagadzira macomposites e316L simbi isina tsvina nemhangura ichishandisa inkjet copper inki munzvimbo inofananidzira laser alloy mumubhedha wehupfu.Gadziriro yemareactors emakemikari uchishandisa nzira itsva yehybrid inkjet uye LPBF iyo inotora mukana wekutungamira kwekupisa kupisa kuderedza saizi uye huremu hwe reactor.Iko mukana wekugadzira zvinhu zvakasanganiswa uchishandisa inkjet ink inoratidzwa.
Vatsvagiri vakatarisa pakusarudzwa kweCu ink precursors uye maitiro ekugadzira ezvakasanganiswa bvunzo zvigadzirwa kuona density yezvinhu, microhardness, kuumbwa, uye kupisa kwekupisa.Ingi mbiri dzemumiriri dzakasarudzwa zvichienderana nekugadzikana kweoxidation, yakaderera kana isina zvinowedzerwa, kuenderana neinkjet printheads, uye zvishoma zvakasara mushure mekutendeuka.
Ingi dzekutanga dzeCufAMP dzinoshandisa fomati yemhangura (Cuf) semunyu wemhangura.Vinyltrimethylcopper(II) hexafluoroacetylacetonate (Cu(hfac)VTMS) imwe inki precursor.Muedzo wemutyairi wakaitwa kuti uone kana kuomeswa nekuora kweinki kunoguma nekusvibiswa kwemhangura yakawanda nekuda kwekutakurwa kwemakemikari ne-zvigadzirwa zvichienzaniswa nekuomeswa kwakajairwa uye kuora kwemafuta.
Kushandisa nzira mbiri, ma microcoupons maviri akagadzirwa uye microstructure yavo yakaenzaniswa nekuona maitiro ekuchinja nzira.Pamutoro we500 gf uye nguva yekubata ye15 s, iyo Vickers microhardness (HV) yakayerwa pachikamu chemuchinjiko weiyo fusion zone yemasampuli maviri.
Schematic yekuyedza kuseta uye nhanho dzekuita dzakadzokororwa pakugadzira 316L SS-Cu inoumbwa masamples akagadzirwa achishandisa nzira yekudziya yemubhedha.Mufananidzo wechikwereti: Murray, JW et al.Tsamba paAdditive Manufacturing.
Zvakaonekwa kuti thermal conductivity yemusanganiswa ndeye 187% yakakwirira kupfuura iyo ye316L simbi isina tsvina, uye microhardness iri 39% yakaderera.Zvidzidzo zveMicrostructural zvakaratidza kuti kudzikisa kuputika kwemukati kunogona kuvandudza kupisa kwekupisa uye michina yezvimiro zvecomposites.Kuti ienderere mberi kupisa kuyerera mukati memuchinjiziri wekupisa, zvinodikanwa kuti usarudze kuwedzera kupisa kwekupisa kwe316L simbi isina tsvina.Iyo composite ine inoshanda yekupisa conductivity ye41.0 W/mK, 2.9 nguva ye316L simbi isina tsvina, uye 39% kuderedza mukuoma.
Kana ichienzaniswa neyakagadzirwa uye yakanyungudutswa 316L simbi isina tsvina, iyo microhardness yemuyero muchikamu chinopisa yaive 123 ± 59 HV, iyo iri pasi ne39%.Iyo porosity yekupedzisira composite yaive 12%, iyo inosanganiswa nekuvapo kwe cavities uye kuputika pakusangana pakati pe SS neCu phases.
Kumasamples mushure mekudziya uye yekudziya dhizaini, kuomarara kwezvikamu zvemuchinjiko weiyo fusion zone yakatemerwa se110 ± 61 HV uye 123 ± 59 HV, zvichiteerana, iri 45% uye 39% yakaderera pane 200 HV yekubiridzira. 316L simbi isina tsvina.Pamusana pekusiyana kukuru kwekushisa kwekunyunguduka kweCu uye 316L simbi isina tsvina, inenge 315 ° C, kuputika mumagetsi akagadzirwa akaumbwa semugumisiro wekuputika kwemvura kunokonzerwa nekuyerera kweCu.

Mukupedzisa, chidzidzo ichi chinoratidza nzira itsva yekugadzira 316L SS-Cu composites ine nani yekupisa conductivity pane 316L SS uchishandisa ingi yemhangura yakapfapfaidzwa.Iyo composite inogadzirwa nekuisa inki mubhokisi regirovhosi uye kuishandura kuita mhangura, wobva wawedzera simbi isina tsvina pamusoro payo, wozosanganisa nekurapa mune laser welder.
Mhedzisiro yekutanga inoratidza kuti methanol-based Cuf-AMP inki inogona kudzika kusvika kumhangura yakachena isina kugadzira copper oxide munzvimbo yakafanana neLPBF maitiro.Iyo inopisa mubhedha nzira yekushandisa uye kushandura inki inogadzira microstructures ine mashoma voids uye tsvina pane yakajairwa post-heating maitiro.
Vanyori vanocherechedza kuti zvidzidzo zvenguva yemberi zvichatsvaga nzira dzekudzikisa ukuru hwezviyo uye kuvandudza kunyunguduka uye kusanganiswa kwezvikamu zveSS neCu, pamwe chete nemagetsi emagetsi ezvinyorwa.
