ʻO ka uhi ʻana i ka vacuum kahi ʻenehana i hana ʻia nā mea kiʻiʻoniʻoni lahilahi e nā ʻano kino.Hoʻokaʻawale ʻia nā ʻātoma o ka mea i loko o ke keʻena māmā mai ke kumu hoʻomehana a paʻi i ka ʻili o ka mea e uhi ʻia.Ua hoʻohana mua ʻia kēia ʻenehana e hana i nā lens optical, e like me nā lens telescope moana.Ma hope ua hoʻonui ʻia i nā kiʻiʻoniʻoni hana ʻē aʻe, hoʻopaʻa i ka alumini plating, ka uhi hoʻonaninani a me ka hoʻololi ʻana i ka ʻili.No ka laʻana, ua uhi ʻia ka pahu kiaʻi me ke gula hoʻohālike, a ua uhi ʻia ka pahi mīkini e hoʻololi i ka ʻulaʻula a me ka paʻakikī.

Hoʻomākaukau ʻia ka papa kiʻiʻoniʻoni i loko o kahi ʻūhā, me ka hoʻopili ʻana i ka metala crystalline, semiconductor, insulator, a me nā kiʻi ʻoniʻoni ʻē aʻe.ʻOiai ke hoʻohana pū nei ka hoʻoheheʻe ʻana i ka mahu kemika e like me ke kaomi haʻahaʻa, ka haʻahaʻa haʻahaʻa a i ʻole ka plasma, ʻo ka uhi ʻana i ka vacuum e pili ana i ka hoʻohana ʻana i nā ʻano kino e waiho ai i nā kiʻiʻoniʻoni lahilahi.ʻEkolu mau ʻano o ka uhi ʻana i ka ʻūhā, ʻo ia ka uhi ʻana i ka evaporation, ka uhi sputtering a me ka uhi ʻana i ka ion.
Ua ʻike mua ʻia ka ʻenehana hoʻoheheʻe ʻia ma ka 1930s, ua hoʻomaka nā noi ʻoihana i nā makahiki 1940 a me 1950, a ua hoʻomaka ka hana ʻoihana nui i nā makahiki 1980.Ua hoʻohana nui ʻia ia i nā ʻoihana e like me ka uila, aerospace, packaging, decor, a me nā stamping wela.ʻO ka hoʻoheheʻe ʻia ʻana e pili ana i ka waiho ʻia ʻana o kekahi metala a i ʻole ka hui metala ma luna o ka ʻili o kahi mea (maʻa mau he mea hao ʻole) ma ke ʻano o kahi ʻāpana kinoea i loko o kahi pōʻaiapuni, ʻo ia ke kaʻina hana hoʻoheheʻe kino.No ka mea, he kiʻi metala pinepine ka uhi ʻana, ua kapa ʻia ʻo ia ka metallization vacuum.Ma ka manaʻo ākea, hoʻokomo pū ʻia ka uhi ʻana i ka ʻūhā o nā kiʻiʻoniʻoni non-metallic hana e like me nā polymers ma ka ʻili o nā mea metala a i ʻole nā mea metala ʻole.Ma waena o nā mea āpau e hoʻopaʻa ʻia, ʻo ka plastic ka mea maʻamau, a ukali ʻia e ka uhi pepa.Ke hoʻohālikelike ʻia me nā metala, keramika, lāʻau a me nā mea ʻē aʻe, loaʻa i nā plastics nā mea maikaʻi o nā kumu he nui, ka maʻalahi o ka hoʻokō ʻana, a me ka hana maʻalahi.No laila, hoʻohana ʻia ka nui o nā plastics a i ʻole nā mea polymer ʻē aʻe e like me ke ʻano hana hoʻonaninani a hoʻohana nui ʻia i nā kaʻa, nā mea hana hale, a me ka hoʻohana ʻana i kēlā me kēia lā.Packaging, mea hoʻonaninani a me nā ʻoihana ʻoihana ʻē aʻe.Eia nō naʻe, ʻo ka hapa nui o nā mea plastik he mau hemahema e like me ka haʻahaʻa o ka ʻili o ka ʻili, lawa ʻole ke ʻano, a me ke kūpaʻa haʻahaʻa.No ka laʻana, hiki ke waiho ʻia kahi kiʻiʻoniʻoni metala lahilahi ma luna o ka ʻili plastik e hāʻawi i ka plastic i kahi ʻano metala ʻālohilohi.Hiki iā ia ke hoʻonui nui i ka pale ʻana o ka ʻili o ka mea, a hoʻonui nui i ka hoʻonaninani a me ka hoʻohana ʻana o ka plastic.
ʻO nā hana o ka vacuum coating he multifaceted, kahi e hoʻoholo ai he waiwai nui kāna mau manawa noi.Ma keʻano laulā, ʻo nā hana nui o ka uhi ʻana me ka hāʻawi ʻana i kahi kiʻekiʻe o ka luster metallic a me ka hopena aniani i ka ʻili o nā ʻāpana i hoʻopaʻa ʻia, e hana ana i ka papa kiʻiʻoniʻoni he mau mea pale maikaʻi loa ma ka mea kiʻiʻoniʻoni, a hāʻawi i ka pale electromagnetic maikaʻi loa a me nā hopena conductive.
