Nā hoʻohana ʻana o ka Osmium Metal ma ka ʻoihana uila
ʻO Osmium kekahi o nā metala kakaikahi loa i loko o ka ʻili o ka Honua a no ka hui platinum group metals (PGM), me platinum, iridium, ruthenium, rhodium, a me palladium. Loaʻa i kēia mea ka helu atomika 76 a ua ʻike ʻia no kona mau waiwai kino ʻokoʻa loa: ke kiʻekiʻe loa o ka density, ke kiʻekiʻe o ka heheʻe ʻana, a me ke kūpaʻa maikaʻi i ka ʻaʻahu a me ka pala ma lalo o kekahi mau kūlana. ʻOiai ʻaʻole i hoʻohana nui ʻia ka osmium e like me nā metala ʻē aʻe e like me ke keleawe, ke kālā, a i ʻole ke gula, he mau noi hoihoi nō ia—ʻoi aku hoʻi i ka wā e koi ai ka ʻoihana i nā mea me ka lōʻihi loa a me ka hana paʻa.
I loko o ka ʻoihana uila, ʻaʻole hoʻohana pinepine ʻia ka osmium ma ke ʻano he mea mua ma muli o kona loaʻa palena ʻole, ke kumukūʻai kiʻekiʻe, a me nā pilikia palekana (ʻoi aku ka pili ʻana i nā hui osmium e hiki ke hana i ka osmium tetroxide ʻawahia). Eia nō naʻe, i kekahi mau noi e pono ai ka ikaika mechanical a me nā waiwai kemika kikoʻī, hiki i ka osmium ke lilo i mea waiwai nui. Eia kekahi mau hoʻohana o ka osmium i loko o ka ʻoihana uila, me nā kumu i koho ʻia ai a me nā palena.
1. Mea Alloy no nā Hoʻopili Uila Kūpaʻa i ka Wear
Hoʻohana pinepine nā ʻāpana uila i nā pilina uila—nā ʻāpana e pā ana e alakaʻi i ke au, e like me nā kuapo, nā relay, nā mea hoʻohui, a i ʻole nā pilina paheʻe. ʻO nā pilikia nui me nā pilina uila, ʻo ia ka ʻaʻahu ma muli o ka friction, ka wela mai ka arcing, a me ka oxidation a i ʻole ka haumia o ka ʻili, kahi e hoʻonui ai i ke kū'ē.
ʻO Osmium, ʻoi aku hoʻi ma ke ʻano metala me nā metala PGM ʻē aʻe e like me ka iridium a i ʻole platinum, e kōkua i:
– Paʻakikī kiʻekiʻe i ʻole e pala koke ka ʻili pili.
– Ke kū'ē i ke komo ʻana i nā noi e pili ana i nā neʻe hana hou.
– Ke kūpaʻa i nā mahana kiʻekiʻe, ka mea e kōkua ai i ka mālama ʻana i ke ʻano a me ka hana ke hana ʻia ka hoʻomehana kūloko.
He mea nui nā pilina uila pale ʻaʻahu i nā mea uila ʻoihana, nā ʻōnaehana hoʻomalu, a i ʻole nā mea hana e pono e hana no nā manawa lōʻihi me ka ʻole o ka mālama pinepine ʻana. Eia nō naʻe, ma muli o ka palena o nā lako osmium, koho pinepine ʻia nā mea hoʻohui osmium no nā noi kikoʻī loa a waiwai nui.
2. Hoʻonui i ke kū'ē ʻana i ka ʻino ʻana o Arcing
I loko o kahi kaapuni uila me kahi au a i ʻole voltage, ke wehe a pani paha ke kuapo, hiki ke hana ʻia kahi ʻāʻī uila. Hiki i kēia ʻāʻī ke "hoʻopau" i ka ʻili pili a hoʻololi i kona mau ʻano: lilo ka ʻili i ʻinoʻino, hana ʻia nā oxides, a piʻi ka pale.
Pono nā mea e hiki ke pale aku i ka ʻānai ʻana o ke ahi e mālama i ka hilinaʻi. Loaʻa iā Osmium nā pono i loko o nā mea hoʻohuihui no ka mea:
– Hoʻemi i ka nui o ka ʻino ʻana ma ka ʻili pili.
– Mālama i kahi ʻili paʻa e kūʻē i nā pōʻaiapuni ʻaʻahu kiʻekiʻe.
ʻOiai ma ka hana ʻoihana hou, ʻoi aku ka hoʻohana pinepine ʻia ʻana o ke kālā, tungsten, a i ʻole nā mea hoʻohuihui ruthenium no nā ʻano like ʻole o nā relays a me nā kuapo, pili mau ka osmium ma ke ʻano he koho mea no nā kūlana koʻikoʻi, ʻoiai ke kūpaʻa a me ke kūpaʻa nā mea nui.
3. Ka uhi ʻana no nā ʻāpana liʻiliʻi me ke kūpaʻa kiʻekiʻe
I ke ao o nā mea uila kikoʻī—no ka laʻana, i nā mea microelectromechanical (Micro-Electro-Mechanical Systems / MEMS), kekahi mau ʻāpana sensor, a me nā mīkini micro e neʻe ana—he mea nui nā uhi ʻili e hōʻemi i ka friction, ka ʻaʻahu, a me nā loli i nā waiwai ma muli o ke kaiapuni.
Ma ke ʻano manaʻo, hiki ke hoʻohana ʻia ka osmium ma ke ʻano he mea uhi no ka mea:
– Paʻakikī loa a hiki ke hoʻonui i ke kū'ē o ka ʻili.
– Kūpaʻa i ka abrasion, kūpono no nā ʻāpana liʻiliʻi e ʻike ana i ka hoʻopili mechanical.
Eia nō naʻe, ʻo ka hoʻohana ʻana i ka osmium ma ke ʻano he uhi he mea maʻamau ʻole ia a ʻoi aku ka maikaʻi o nā mea uhi pono e like me ka nitride (TiN), kalapona e like me ka DLC (kalapona e like me ke daimana), a i ʻole nā mea hoʻohui PGM ʻē aʻe i ʻoi aku ka palekana a me ka maʻalahi o ka hana ʻana. Eia nō naʻe, i ka noiʻi ʻana i nā mea a i ʻole nā hoʻohana kikoʻī, hiki i ka osmium ke lilo i moho ma muli o kona mau waiwai mechanical kiʻekiʻe.
4. Nā ʻāpana o nā mea hana uila kikoʻī a me nā mea hana kūikawā
Ma mua o ka ulu wikiwiki ʻana o ka ʻenehana semiconductor a me nā mea hou, ua hoʻohana kekahi mau mea hana pololei i nā metala PGM no nā ʻāpana e pono ai ke kūpaʻa o ka dimensional a me ka lōʻihi. Ua ʻike mua ʻia ʻo Osmium no kona hoʻohana ʻana i nā ʻāpana me nā pilina palupalu a me nā mīkini kikoʻī.
Ma ke kaiapuni uila, nā noi e like me:
- nā mea ana me nā pilina mechanical maikaʻi loa,
- nā mea hana me nā koi ola lawelawe lōʻihi,
- ʻōnaehana hana hou ʻana o ka pilina kiʻekiʻe,
Hiki paha iā ʻoe ke noʻonoʻo i nā mea hoʻohuihui i loaʻa ka osmium. ʻOiai he mea kakaikahi ia i nā huahana i hana nui ʻia, ua like ke kumumanaʻo: he mea pono ka osmium i ka wā e lilo ai ke kūpaʻa a me ke kūpaʻa i mau mea nui.
5. Nā Mea Kākoʻo no ka Noiʻi ʻEpekema Uila a me nā Mea Hana
ʻIke ʻia ke kuleana o Osmium ma ka noiʻi, ʻaʻole wale ka hana nui ʻana. I ka hoʻomohala ʻana i nā mea uila, hiki i nā mea noiʻi ke ʻimi i ka osmium i loko o:
- nā haʻawina alloy no nā pilina uila hanauna hou,
- ka hoʻāʻo ʻana i ke kūpaʻa o ka ʻili ma lalo o nā kūlana koʻikoʻi,
- nā hoʻokolohua ma nā waiwai uila a me nā ʻano kristal o nā metala kaumaha.
Eia kekahi, he ʻokoʻa ka nui o ka osmium a me nā ʻano kino, e hoihoi ai i ka noiʻi e pili ana i nā hanana o ka ʻili, ke kū'ē ʻana i ka diffusion, a i ʻole ke kūpaʻa wela i kekahi mau ʻāpana.
6. Nā Palena o ka Hoʻohana ʻana o Osmium ma ka ʻOihana Uila
ʻOiai kona mau pono he nui, ʻaʻole he mea "versatile" ka osmium. Aia kekahi mau mea keakea nui e pale ana i kona hoʻohana nui ʻia:
a) Ka nele a me nā kumukūʻai kiʻekiʻe
ʻO Osmium kekahi o nā mea laha ʻole. ʻO kāna hana ʻana he huahana ia o ka nickel, keleawe, a i ʻole nā mea ʻeli PGM ʻē aʻe. ʻO ka hopena, ua kaupalena ʻia kāna lako, a hiki ke kiʻekiʻe a loli ke kumukūʻai. ʻO ka ʻoihana uila, ka mea e hana ana i nā miliona o nā ʻāpana, makemake i nā mea me kahi lako paʻa.
b) Nā Pilikia Hana
He kiʻekiʻe ke kiko heheʻe o ka Osmium a me nā waiwai e hoʻolilo ai i kāna hana metallurgical i mea paʻakikī ma mua o nā metala maʻamau. ʻO ke kaʻina hana ʻana, ka hoʻohui ʻana, a i ʻole ke kūkulu ʻana, pono paha i nā ʻenehana kūikawā.
c) Nā Pōʻino Palekana o nā Pūhui Osmium
ʻO kahi hopohopo nui ka hiki ke hoʻokumu ʻia ʻana o ka osmium tetroxide (OsO₄), kahi hui ʻawahia loa a lele. Ma nā wahi ʻoihana, pono kēia i nā kaʻina hana palekana koʻikoʻi a me nā kaohi kaʻina hana. Ua alakaʻi kēia pilikia i nā mea hana he nui e koho i nā koho ʻē aʻe palekana.
d) Nā Koho Mea Hana Hou Aʻe
Hiki i nā noi uila he nui ke hoʻokō i nā kikoʻī me nā mea ʻē aʻe: ke gula no ka conductivity a me ke kūpaʻa i ka corrosion, ke kālā no ka conductivity kiʻekiʻe, ka tungsten no ke kūpaʻa wela, a me ka ruthenium/rhodium no kekahi mau ʻano pilina. No laila, hoʻohana pinepine ʻia ka osmium ke hoʻokō maoli ʻia nā koi hana kikoʻī.
7. Nā Manaʻolana no Osmium i nā ʻElekole Hou
I ka wā e hiki mai ana, e noho mau ana ka osmium i mea kūikawā, ma mua o kahi mea mua. Eia nō naʻe, aia ka hiki ke hoʻomau ʻia ka noʻonoʻo ʻana i loko o:
- hoʻopili me ka huila no ka hoʻohana nui ʻana,
- ka noiʻi ʻili a me ka tribology (ʻepekema o ka friction a me ke komo ʻana) ma nā ʻāpana micro,
– nā noi niche e koi ana i ka lōʻihi o ka mīkini.
Me ka hoʻonui ʻia o ka pono no nā mea paʻa, ka miniaturization, a me nā ʻōnaehana uila e hana ana i nā wahi koi (e like me ka ʻoihana kaumaha, ka pale kaua, a i ʻole ka ʻimi ʻana), ʻo ka hoihoi i nā mea hana kiʻekiʻe—me ka osmium—e pili mau ana paha, ʻoiai ma ke ʻano o nā alloys a i ʻole nā ʻiliʻili lahilahi.
Ka hopena
He metala laha ʻole ka Osmium me nā waiwai mechanical a me thermal koʻikoʻi, e lilo ana ia i mea pono loa i ka ʻoihana uila, ʻoiai no nā noi e pono ai ke kūpaʻa i ka ʻaʻahu, ke kūpaʻa o ka mahana kiʻekiʻe, a me ke kūpaʻa i ka ʻino ʻana o ka arcing. ʻO Osmium ka mea kūpono loa i nā alloys no nā pilina uila, nā ʻāpana kikoʻī, a ma ke ʻano he kākoʻo no ka noiʻi ʻana i nā mea.
Eia nō naʻe, ua kaupalena ʻia kona hoʻohana ʻana e ka nele, ke kumukūʻai, ka paʻakikī o ka hana ʻana, a me nā hopohopo palekana e pili ana me ka osmium tetroxide. No kēia mau kumu, ʻaʻole hoʻohana pinepine ʻia ka osmium i nā mea uila i hana nui ʻia, akā he mea nui ia ma ke ʻano he hopena niche no nā noi hana kiʻekiʻe loa.
Inā makemake ʻoe, hiki iaʻu ke hoʻohui i kahi ʻāpana "nā laʻana noi ma nā hāmeʻa maoli" (nā relay ʻoihana, nā kuapo pololei, a i ʻole nā mea hoʻohui kūikawā) a i ʻole e hōʻuluʻulu i kahi mana hoʻonaʻauao hou aʻe o ka ʻatikala piha me ka papa inoa puke a me nā ʻōlelo kuhikuhi.
