Hoʻohana mākou i nā kuki e hoʻomaikaʻi i kou ʻike.Ma ka hoʻomau ʻana i kēia pūnaewele, ʻae ʻoe i kā mākou hoʻohana ʻana i nā kuki.ʻIke hou aku.
Ma kahi ʻatikala hou i paʻi ʻia ma ka puke pai Additive Manufacturing Letters, kūkākūkā nā mea noiʻi i ke kaʻina hoʻoheheʻe laser no nā hui keleawe e pili ana i ka 316L stainless steel.

ʻOiai e laha ana ka hoʻoili ʻana o ka wela i loko o kahi paʻa like like, hiki ke hele ka wela ma waena o kahi paʻa paʻa ma ke ala o ke kūʻē liʻiliʻi.I loko o nā mea hoʻoheheʻe metala, ua ʻōlelo ʻia e hoʻohana i ka anisotropy o ka conductivity thermal a me ka permeability e hoʻonui i ka nui o ka hoʻoili wela.
Eia kekahi, manaʻo ʻia ka conduction thermal anisotropic e hōʻemi i nā poho parasitic i hoʻokumu ʻia e ka conduction axial i nā mea hoʻololi wela.Ua hoʻohana ʻia nā ʻano hana like ʻole no ka hoʻololi ʻana i ka conductivity thermal o nā alloys a me nā metala.ʻAʻole kūpono kēia mau ala no ka hoʻonui ʻana i nā hoʻolālā hoʻokele kuhikuhi no ka kahe wela o nā ʻāpana metala.
Hoʻokumu ʻia nā Metal Matrix Composites (MMC) mai nā pauka wili pōpō me ka hoʻohana ʻana i ka ʻenehana laser melting in powder bed (LPBF).Ua manaʻo ʻia kahi ʻano LPBF hybrid hou e hana i nā ʻāpana ODS 304 SS ma o ka doping yttrium oxide precursors i loko o kahi papa o 304 SS pauka ma mua o ka hoʻopaʻa ʻana i ka laser me ka hoʻohana ʻana i ka ʻenehana inkjet piezoelectric.ʻO ka pōmaikaʻi o kēia ala ʻo ia ka hiki ke hoʻololi i nā waiwai waiwai ma nā wahi like ʻole o ka papa pauka, e hiki ai iā ʻoe ke hoʻomalu i nā waiwai waiwai i loko o ka nui o ka hana o ka mea hana.
Hōʻike hoʻohālike o ke ʻano moe wela no (a) hoʻomehana ʻana a me (b) hoʻololi ʻīnika.Kiʻi kiʻi: Murray, JW et al.Nā leka ma ka hana hoʻohui.
I loko o kēia noiʻi ʻana, ua hoʻohana nā mea kākau i ka inika Cu inkjet e hōʻike i ke ʻano hoʻoheheʻe laser no ka hana ʻana i nā composites metala matrix me ka conductivity wela ʻoi aku ka maikaʻi ma mua o 316L stainless steel.No ka hoʻohālikelike ʻana i ke ʻano hui ʻana o ka moena inkjet-powder moena, ua hoʻopaʻa ʻia kahi papa lepo kila kila me nā inika copper precursor a ua hoʻohana ʻia kahi waihona wai hou e hoʻomalu i ka pae o ka oxygen i ka wā o ka hana laser.
Ua hana ka hui i nā mea hoʻohui o 316L stainless steel me ke keleawe me ka hoʻohana ʻana i ka inika keleawe inkjet i loko o kahi kaiapuni e hoʻohālikelike ana i ka alloy laser i loko o kahi moena pauka.Ka hoʻomākaukau ʻana i nā reactors kemika me ka hoʻohana ʻana i kahi ʻenekini hybrid hou a me ka ʻenehana LPBF e hoʻohana pono i ka hoʻokele thermal direction e hōʻemi i ka nui a me ke kaumaha o ka reactor.Hōʻike ʻia ka hiki ke hana i nā mea hoʻohui me ka hoʻohana ʻana i ka inika inkjet.
Ua nānā ka poʻe noiʻi i ke koho ʻana i nā mea hoʻokalakupua Cu ink a me ke kaʻina hana no nā huahana hoʻāʻo composite e hoʻoholo ai i ka paʻa waiwai, microhardness, haku mele, a me ka diffusivity thermal.Ua koho ʻia ʻelua ʻīnika moho ma muli o ke kūpaʻa o ka oxidation, haʻahaʻa a ʻaʻohe mea hoʻohui, kūpono me nā poʻo paʻi inkjet, a me ke koena liʻiliʻi ma hope o ka hoʻololi ʻana.
Hoʻohana nā inika CufAMP mua i ka copper formate (Cuf) e like me ka paʻakai keleawe.ʻO Vinyltrimethylcopper(II) hexafluoroacetylacetonate (Cu(hfac)VTMS) kekahi mea ʻīnika mua.Ua mālama ʻia kahi hoʻokolohua hoʻokele no ka ʻike ʻana inā ʻoi aku ka nui o ke keleawe a me ka hoʻomaloʻo ʻana a me ka hoʻoheheʻe wela o ka ʻīnika ma muli o ka lawe ʻana o nā huahana kemika i hoʻohālikelike ʻia me ka maloʻo maʻamau a me ka hoʻoheheʻe wela.
Ke hoʻohana nei i nā ʻano ʻelua, ua hana ʻia ʻelua microcoupons a me kā lākou microstructure i hoʻohālikelike ʻia e hoʻoholo i ka hopena o ke ʻano hoʻololi.Ma ka ukana o 500 gf a me ka manawa paʻa o 15 s, ka Vickers microhardness (HV) ua ana ma ke kea pauku o ka fusion zone o elua laana.
Hoʻolālā ʻia o ka hoʻonohonoho hoʻokolohua a me nā kaʻina hana i hana hou ʻia no ka hana ʻana i nā laʻana 316L SS–Cu i haku ʻia me ka hoʻohana ʻana i ke ʻano moe wela.Kiʻi kiʻi: Murray, JW et al.Nā leka ma ka hana hoʻohui.
Ua ʻike ʻia ʻo ka thermal conductivity o ka composite he 187% kiʻekiʻe ma mua o ka 316L stainless steel, a ʻo ka microhardness he 39% haʻahaʻa.Ua hōʻike ʻia nā haʻawina microstructural ʻo ka hōʻemi ʻana i ka haʻihaʻi interfacial hiki ke hoʻomaikaʻi i ka conductivity thermal a me nā waiwai mechanical o nā composites.No ka holo ʻana o ka wela i loko o ka mea hoʻololi wela, pono e hoʻonui i ka conductivity thermal o 316L kila kila.He 41.0 W/mK ko ka composite, he 2.9 manawa o ko 316L stainless steel, a he 39% ka emi o ka paakiki.
Hoʻohālikelike ʻia me ke kila kila 316L i hoʻopaʻa ʻia a hoʻopaʻa ʻia, ʻo ka microhardness o ka hāpana ma ka papa wela he 123 ± 59 HV, ʻo ia ka 39% haʻahaʻa.ʻO ka porosity o ka composite hope loa he 12%, e pili ana me ka hele ʻana o nā lua a me nā māwae ma ke kikowaena ma waena o nā pae SS a me Cu.
No nā laʻana ma hope o ka hoʻomehana ʻana a me ka papa wela, ua hoʻoholo ʻia ka microhardness o nā ʻāpana keʻa o ka fusion zone e like me 110 ± 61 HV a me 123 ± 59 HV, ʻo ia ka 45% a me 39% haʻahaʻa ma mua o 200 HV no ka forged-annealed. 316L kila kila.Ma muli o ka ʻokoʻa nui o ka hoʻoheheʻe ʻana o Cu a me 316L stainless steel, e pili ana i 315 ° C, ua hoʻokumu ʻia nā māwae i loko o nā composites i hana ʻia ma muli o ka hoʻoheheʻe ʻana o ka fluidization i hana ʻia e ka fluidization o Cu.
Kiʻi BSE (hema luna) a me ka palapala ʻāina o nā mea (Fe, Cu, O) ma hope o ka hoʻomehana ʻana o ka laʻana, loaʻa ma ka WDS analysis.Kiʻi kiʻi: Murray, JW et al.Nā leka ma ka hana hoʻohui.
I ka hopena, hōʻike kēia haʻawina i kahi ala hou e hana ai i nā composites 316L SS-Cu me ka conductivity thermal maikaʻi aʻe ma mua o 316L SS me ka hoʻohana ʻana i ka inika keleawe i hoʻoheheʻe ʻia.Hana ʻia ka composite ma ka hoʻokomo ʻana i ka ʻīnika i loko o ka pahu mīkina lima a hoʻololi iā ia i keleawe, a laila hoʻohui i ka pauka kila kila ma luna, a laila hui ʻia a hoʻōla i kahi welder laser.
Hōʻike nā hualoaʻa mua e hiki ke hoʻohaʻahaʻa i ka inika Cuf-AMP i hoʻokumu ʻia methanol i ke keleawe maʻemaʻe me ka ʻole o ka hana ʻana i ka copper oxide i kahi kaiapuni e like me ke kaʻina LPBF.ʻO ke ʻano moe wela no ka noi ʻana a me ka hoʻololi ʻana i ka ʻīnika e hana i nā microstructures me ka liʻiliʻi o nā lua a me nā haumia ma mua o nā kaʻina hana maʻamau ma hope o ka wela.
Hoʻomaopopo nā mea kākau e ʻimi nā haʻawina e hiki mai ana i nā ala e hōʻemi ai i ka nui o ka palaoa a hoʻomaikaʻi i ka hoʻoheheʻe ʻana a me ka hui ʻana o nā māhele SS a me Cu, a me nā ʻano mechanical o nā composites.
