Hoʻohana mākou i nā kuki e hoʻonui i kou ʻike. Ma ka hoʻomau ʻana i ka nānā ʻana i kēia pūnaewele e ʻae ʻoe i kā mākou hoʻohana ʻana i nā kuki. ʻIke hou aku.
I loko o kahi ʻatikala hou i paʻi ʻia ma ka puke pai Additive Manufacturing Letters, kūkākūkā nā mea noiʻi i ka pono o ka spatter stainless steel i kālai ʻia i kemika no ka hoʻonui ʻana i ke ola pauka i ka hana hoʻohui.

ʻO ka Metal Laser Powder Bed Fusion (LPBF) Hoʻopuka ʻia nā ʻāpana paʻipaʻi e nā kulu hoʻoheheʻe ʻia i hoʻokuʻu ʻia mai ka wai hoʻoheheʻe a i ʻole nā ​​​​palapala pauka i wela a kokoke a ma luna paha o ka helu heheʻe i ko lākou hele ʻana ma ke kukui laser.
ʻOiai ka hoʻohana ʻana i kahi kaiapuni inert, ʻo ke kiʻekiʻe o ka reactivity o ka metala kokoke i kona wela hoʻoheheʻe e paipai i ka oxidation.
No ka mea ʻoi aku ka kiʻekiʻe o ke kaomi ʻāpana o ka oxygen i ka LPBF ma mua o ka atomization gas, ua hoʻonui ʻia ka hiki ke hoʻopaʻa ʻia me ka oxygen.
ʻIke ʻia ʻo nā kila kila a me ka nickel-based spatters e oxidize wikiwiki, e hana ana i nā mokupuni a hiki i kekahi mau mika i ka mānoanoa.
(a) SEM kiʻi o nā ʻāpana ʻāpana kila kila, (b) ke ʻano hoʻokolohua o ka etching kemika wela, (c) LPBF mālama ʻana i nā ʻāpana spatter deoxidized.
I loko o kēia noiʻi ʻana, ua hoʻohana nā mea kākau i kahi ʻenehana etching hou e hoʻoneʻe i nā oxides mai ka ʻili o nā pauka splash oxidized stainless steel.
Ua hōʻike ka hui pehea e hoʻoneʻe ai i nā ʻokikene mai loko mai o nā ʻāpana paʻipaʻi kila kila, ʻoi aku ka nui o nā mea i hoʻokaʻawale ʻia me ka hoʻohana ʻana i nā ʻenehana kemika e hana ai i nā mokupuni ʻokikene waiwai ʻo Si- a me Mn ma ka ʻili o ka pauka.
Ua nānā ka poʻe noiʻi i ka mahana a me nā etchants kila kila ʻelua.
ʻO kēlā me kēia ʻāpana LPBF i hana ʻia mai ka sputtered, etch spatter, a me ka pauka maʻemaʻe. ʻO ke kiʻi kiʻekiʻe kiʻekiʻe e hōʻike ana ua hoʻopau ʻia ka papa oxide e laha nei ma ka track sputtered ma ke ala sputtered etched.
ʻO ka uhi ʻana o ka oxide ma 316L stainless steel splash powder i hoʻemi ʻia e ka helu o 10, mai 7% a 0.7% ma hope o ka hoʻomehana ʻia ʻana o ka reagent o Ralph i 65 ° C i loko o ka wai ʻauʻau no 1 hola. Ma ka palapala ʻana i ka wahi nui, hōʻike ʻia ka ʻikepili EDX i ka emi ʻana o nā pae oxygen mai 13,5% a 4,5%.
Loaʻa i ka etched spatter ka haʻahaʻa o ka oxide slag coating ma ka ʻaoʻao track i hoʻohālikelike ʻia me ka spatter. Eia kekahi, hoʻonui ka etching kemika o ka pauka i ka assimilation o ka pauka ma ke ala.
Ma waena o ka 45-63 µm ka nui o ka sieve, ʻo ke koena o nā ʻāpana i hoʻohui ʻia i loko o nā pauka i kālai ʻia a ʻaʻole i hoʻopaʻa ʻia e wehewehe i ke kumu o ka like ʻana o nā puʻupuʻu o nā pauka i kālai ʻia a me nā pauka i hoʻopaʻa ʻia, ʻoiai ʻo ka nui o nā pauka kumu ma kahi o 50% ka nui.
He haʻahaʻa ka uhi ʻia ʻana o ka oxide spatter ma ka ʻili o ke ala e hoʻohālikelike ʻia me ka spatter. Ke wehe ʻia nā oxides me ke kemika, hōʻike ka pauka semi-paʻa a me ka ʻole o ka paʻa maikaʻi ʻana o nā oxide i hoʻemi ʻia, ʻo ia ka mea i ʻoi aku ka maikaʻi o ka pulu.
Schematic e hōʻike ana i nā pōmaikaʻi o ka mālama ʻana i ka LPBF i ka wā e wehe ai i nā oxides mai ka pauka splash i nā ʻōnaehana kila kila. Loaʻa 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 hoʻohou hou i nā pauka i hoʻoheheʻe ʻia i loko o ka reagent a Ralph, kahi hopena o ka ferric chloride a me ka cupric chloride i loko o ka waikawa hydrochloric.
Manaʻo ka poʻe kākau e hiki ke hoʻomaikaʻi ʻia a hoʻohana ʻia ma ke ʻano ākea e hoʻohou i nā ʻāpana spatter hou a i ʻole nā ​​pauka LPBF, a laila e hoʻonui ai i ka waiwai o nā mea waiwai waiwai.
