Hoʻohana mākou i nā kuki e hoʻomaikaʻi i kou ʻike. Ma ka hoʻomau ʻana e nānā i kēia pūnaewele, ʻae ʻoe i kā mākou hoʻohana ʻana i nā kuki. ʻIke hou aku.
Ma kahi ʻatikala i paʻi ʻia ma ka puke pai Additive Manufacturing Letters, ua kūkākūkā nā kānaka noiʻi i ka pono o ka spatter kila kila i ʻoki ʻia me ka kemika no ka hoʻolōʻihi ʻana i ke ola o ka pauka i ka hana hoʻohui.
Noiʻi: Ke hoʻolōʻihi nei i ke ola o ka pauka i ka hana ʻana i nā mea hoʻohui: Ke kālai kemika o ka spatter kila kila. Kiʻi kiʻi: MarinaGrigorivna/Shutterstock.com
Hoʻopuka ʻia nā ʻāpana splash o ka Metal Laser Powder Bed Fusion (LPBF) e nā kulu heheʻe i hoʻokuke ʻia mai ka loko heheʻe a i ʻole nā ​​ʻāpana pauka i hoʻomehana ʻia a kokoke a ma luna paha o ke kiko heheʻe i ko lākou hele ʻana ma ke kukuna laser.
ʻOiai ka hoʻohana ʻana i kahi ʻano inert, ʻo ka reactivity kiʻekiʻe o ka metala kokoke i kona mahana hoʻoheheʻe e paipai i ka oxidation. ʻOiai ʻo nā ʻāpana spatter i hoʻokuʻu ʻia i ka wā o ka LPBF e hoʻoheheʻe ʻia ma ka liʻiliʻi no ka manawa pōkole ma ka ʻili, hiki ke hana ʻia ka hoʻolaha ʻana o nā mea volatile i ka ʻili, a ʻo kēia mau mea me ka makemake kiʻekiʻe no ka oxygen e hana i nā papa oxide mānoanoa.
ʻOiai ʻoi aku ke kiʻekiʻe o ke kaomi hapa o ka oxygen ma LPBF ma mua o ke kaomi ʻana o ke kinoea, ua hoʻonui ʻia ka hiki ke hoʻopaʻa ʻia me ka oxygen.
Ua ʻike ʻia nā ʻōpala kila kila a me nā mea hao nickel e hoʻopau koke i ka oxidation, e hana ana i nā mokupuni a hiki i kekahi mau mika ka mānoanoa. Eia kekahi, ʻo nā kila kila a me nā mea hao nickel, e like me nā mea e hana ana i nā ʻōpala oxide ʻano mokupuni, ʻoi aku ka maʻamau o nā mea i hana ʻia ma LPBF, a ke hoʻopili nei i kēia ʻano hana i nā ʻōpala metala LPBF maʻamau e hōʻike i ka hoʻohou kemika he mea koʻikoʻi ia i ka Powder ma ke ʻano maʻamau.

Ma kēia haʻawina, ua hoʻohana nā mea kākau i kahi ʻenehana etching kemika hou e wehe i nā oxides mai ka ʻili o nā pauka splash kila kila i hoʻopau ʻia. Hoʻohana ʻia ka hoʻoheheʻe ʻana o ka metala a puni a ma lalo o nā mokupuni oxide ma ka pauka ma ke ʻano he ʻano hana mua no ka wehe ʻana i ka oxide, kahi e ʻae ai i ka wehe ʻana i ka oxide ʻoi aku ka ikaika. Ua kānana ʻia nā pauka splash, etch a me nā pauka puʻupaʻa i ka pae like o ka nui o ka pauka no ka hana ʻana o LPBF.
Ua hōʻike ka hui pehea e wehe ai i nā oxides mai nā ʻāpana spatter kila kila, ʻoiai nā mea i hoʻokaʻawale ʻia me ka hoʻohana ʻana i nā ʻano hana kemika e hana i nā mokupuni oxide waiwai Si- a me Mn ma ka ʻili pauka. Ua hōʻiliʻili ʻia he 316L o ka spatter mai ka moena pauka o nā paʻi LPBF a ua ʻoki ʻia me ke kemika ma ka hoʻokomo ʻana. Ma hope o ka nānā ʻana i nā ʻāpana āpau i ka nui like, hana ʻo LPBF iā lākou i hoʻokahi ala me ka spatter i ʻoki ʻia i hoʻomaikaʻi ʻia a me ke kila kila puʻupaʻa.
Ua nānā nā mea noiʻi i ka mahana a me ʻelua mau mea ʻoki kila kila like ʻole. Ma hope o ka nānā ʻana i ka nui like, ua hana ʻia nā ala hoʻokahi LPBF ma ka hoʻohana ʻana i nā pauka puʻupaʻa like, nā pauka splash, a me nā pauka splash i ʻoki pono ʻia.
Nā kaha LPBF pākahi i hana ʻia mai ka spatter, etch spatter, a me ka pauka pristine. Hōʻike ke kiʻi hoʻonui kiʻekiʻe ua hoʻopau ʻia ka papa oxide i loaʻa ma ke ala sputtered ma ke ala sputtered i etch ʻia. Ua hōʻike ka pauka mua aia nō kekahi mau oxides. Kiʻi kiʻi: Murray, J. W, et al, Additive Manufacturing Letters
Ua emi ka uhi ʻana o ka ʻāpana oxide ma ka pauka splash kila kila 316L ma kahi manawa o 10, mai 7% a i 0.7% ma hope o ka hoʻomehana ʻia ʻana o ka reagent a Ralph i 65 °C i loko o ka wai ʻauʻau no 1 hola. Ke palapala ʻāina nei i ka ʻāpana nui, ua hōʻike ka ʻikepili EDX i ka emi ʻana o nā pae oxygen mai 13.5% a i 4.5%.
ʻOi aku ka haʻahaʻa o ka uhi ʻōpala oxide o ka spatter i kālai ʻia ma ka ʻili o ke ala i hoʻohālikelike ʻia me ka spatter. Eia kekahi, hoʻonui ka etching kemika o ka pauka i ka hoʻopili ʻia ʻana o ka pauka ma ke ala. Loaʻa i ka etching kemika ka hiki ke hoʻomaikaʻi i ka hiki ke hoʻohana hou ʻia a me ke kūpaʻa o ka spatter a i ʻole nā ​​pauka hoʻohana nui i hana ʻia mai nā pauka kila kila i hoʻohana nui ʻia a kū i ka pala.
Ma ka laulā holoʻokoʻa o ka sieve 45-63 µm, ʻo nā ʻāpana i koe i hoʻopili ʻia i loko o nā pauka spatter i kālai ʻia a me ka ʻole i kālai ʻia e wehewehe i ke kumu e like ai nā nui o nā pauka i kālai ʻia a me ka pīpī ʻia, ʻoiai ʻo ka nui o nā pauka mua he 50% ka nui. Ua ʻike ʻia nā pauka i hoʻopili ʻia a i ʻole nā ​​pauka e hana ana i ka satelite e hoʻopilikia i ka nui o ka nui a no laila ka nui.
ʻOi aku ka haʻahaʻa o ka uhi ʻōpala oxide o ka etched spatter ma ka ʻili o ke ala i hoʻohālikelike ʻia me ka spatter. Ke wehe ʻia nā oxides me ke kemika, hōʻike nā pauka semi-bound a me nā pauka ʻōlohelohe i nā hōʻike o ka hoʻopaʻa maikaʻi ʻana o nā oxides i hoʻemi ʻia, kahi i hāʻawi ʻia i ka maʻalahi o ka pulu ʻana.
ʻO ke kiʻikuhi e hōʻike ana i nā pono o ka mālama ʻana o ka LPBF i ka wā e wehe kemika ai i nā oxides mai ka pauka splash i nā ʻōnaehana kila kila. Hoʻokō ʻia ka wettability maikaʻi loa ma ka hoʻopau ʻana i nā oxides. Kiʻi kiʻi: Murray, J. W, et al, Additive Manufacturing Letters
I ka hōʻuluʻulu manaʻo, ua hoʻohana kēia haʻawina i kahi kaʻina hana etching kemika e hana hou i nā pauka spatter kila kila i hoʻopau ʻia me ka kemika ma ka hoʻokomo ʻana i loko o ka reagent a Ralph, kahi hopena o ka ferric chloride a me ka cupric chloride i loko o ka waikawa hydrochloric. Ua ʻike ʻia ʻo ka hoʻokomo ʻana i loko o ka hopena etchant Ralph i hoʻomehana ʻia no 1 hola ua hopena i ka emi ʻana o 10 mau manawa i ka uhi ʻana o ka ʻāpana oxide ma ka pauka i pīpī ʻia.
Manaʻo nā mea kākau he hiki ke hoʻomaikaʻi ʻia a hoʻohana ʻia ke kālai kemika ma kahi ākea e hoʻohou i nā ʻāpana spatter i hoʻohana hou ʻia a i ʻole nā ​​​​pauka LPBF, a laila e hoʻonui ai i ka waiwai o nā mea pauka pipiʻi.

Ma ka Advanced Materials i Iune 2022, ua kamaʻilio ʻo AZoM me Ben Melrose o International Syalons e pili ana i ka mākeke mea holomua, ka ʻoihana 4.0, a me ka hoʻoikaika ʻana i ka ʻupena zero.
Ma Advanced Materials, ua kamaʻilio ʻo AZoM me Vig Sherrill o General Graphene e pili ana i ka wā e hiki mai ana o graphene a pehea e hōʻemi ai kā lākou ʻenehana hana hou i nā kumukūʻai e wehe i kahi honua hou o nā noi i ka wā e hiki mai ana.
Ma kēia hālāwai ninaninau, kamaʻilio ʻo AZoM me ka Pelekikena o Levicron ʻo Kauka Ralf Dupont e pili ana i ka hiki o ka spindle motika (U)ASD-H25 hou no ka ʻoihana semiconductor.
E ʻike i ka OTT Parsivel², kahi mika neʻe laser hiki ke hoʻohana ʻia e ana i nā ʻano ua āpau. Hiki iā ia ke hōʻiliʻili i ka ʻikepili ma ka nui a me ka wikiwiki o nā ʻāpana e hāʻule ana.
Hāʻawi ʻo Environics i nā ʻōnaehana permeation ponoʻī no nā ʻōmole permeation hoʻokahi a nui paha.
ʻO ka MiniFlash FPA Vision Autosampler mai Grabner Instruments he autosampler 12-kūlana. He mea pono hana automation ia i hoʻolālā ʻia no ka hoʻohana ʻana me ka MINIFLASH FP Vision Analyzer.
Hāʻawi kēia ʻatikala i kahi loiloi hopena o ke ola o nā pila lithium-ion, me ka nānā ʻana i ka hana hou ʻana i ka nui o nā pila lithium-ion i hoʻohana ʻia e hiki ai i nā ʻano hoʻokokoke a hoʻomau i ka hoʻohana ʻana a me ka hoʻohana hou ʻana i nā pila.
ʻO ka palaho ka hōʻino ʻia ʻana o kahi metala hao ma muli o ka ʻike ʻia ʻana e ke kaiapuni. Hoʻohana ʻia nā ʻano hana like ʻole e pale aku i ka hōʻino ʻia ʻana o nā metala hao i hōʻike ʻia i nā kūlana lewa a i ʻole nā ​​​​​​kūlana ʻē aʻe.
Ma muli o ka hoʻonui ʻia ʻana o ke koi no ka ikehu, piʻi pū ke koi no ka wahie nukelea, kahi e alakaʻi hou aku ai i ka hoʻonui nui ʻana o ke koi no ka ʻenehana nānā ma hope o ka irradiation (PIE).
