I loko o nā makahiki, ua nui nā holomua ma ke kahua o ka ʻenehana uhi, ʻo kekahi o ia ka hiki ʻana mai o ka ʻenehana electron beam PVD (Physical Vapor Deposition). Hoʻohui kēia ʻenehana ʻokiʻoki i ka maikaʻi o ka evaporation electron beam me ka pololei o PVD e hana i kahi kaʻina hana hoʻonaninani maikaʻi a kiʻekiʻe.
No laila, he aha ka e-beam PVD? Ma kahi pōkole, pili ia i ka waiho ʻana i nā kiʻiʻoniʻoni lahilahi ma luna o nā ʻili like ʻole me ka hoʻohana ʻana i kahi kukuna o nā electrons ikaika nui. Hoʻopau kēia kukuna i ka mea i hoʻopaʻa ʻia, a laila condenses ma luna o ka substrate i makemake ʻia e hana i kahi uhi lahilahi a like. ʻO ka hopena he hopena lōʻihi a nani hoʻi e hana ai i ka e-beam PVD i koho mua no nā ʻano noi like ʻole.
ʻO kekahi o nā pono nui o ka e-beam PVD ka hiki ke hoʻopaʻa maʻalahi i nā ʻano paʻakikī a me nā hale. ʻO ia ke ʻano o nā ʻoihana e like me ka automotive, aerospace a me nā uila hiki ke pōmaikaʻi nui mai kēia ʻenehana. Inā he pale pale ia no nā ʻāpana mokulele a i ʻole ka hoʻopau hoʻonaninani no nā mea uila uila, hāʻawi ka electron beam PVD i ka hana ʻokoʻa.
ʻO kekahi hiʻohiʻona ʻē aʻe o ka electron beam PVD ʻo ia kona ʻoluʻolu kaiapuni. ʻAʻole like me nā ʻenehana uhi kuʻuna, e pili pinepine ana i nā kemika weliweli, ʻo ka electron beam PVD kahi hana maʻemaʻe a hoʻomau. Hoʻopuka ʻo ia i nā ʻōpala liʻiliʻi a loaʻa ka hopena maikaʻi ʻole i ke kaiapuni, i mea kūpono no nā ʻoihana e manaʻo nei e hōʻemi i kā lākou kapuaʻi kalapona.
Eia kekahi, ʻo ka electron beam PVD coating he adhesion maikaʻi loa a me ka paʻakikī, e hōʻoiaʻiʻo ana i ka pale mau loa i ka ʻaʻahu, corrosion a me nā ʻano ʻano degradation ʻē aʻe. Hiki i ka ikehu kiʻekiʻe o ka electron beam ka mana pololei ma luna o ka mānoanoa a me ka hoʻohui ʻana o ka uhi, e ʻae i nā ʻenekini e hoʻopili i ka uhi e hoʻokō i nā koi kikoʻī.
Ua puka hou mai nei ka lono ua hoʻolaha kahi keʻena noiʻi alakaʻi i kahi holomua o ka ʻenehana PVD beam electron. Ua lanakila kā lākou hui i ka hoʻonui nui ʻana i ka helu deposition me ka ʻole o ka hoʻopaʻapaʻa ʻana i ka pono o ka uhi. Ke wehe nei kēia holomua i nā mea hou no nā ʻoihana e koi ana i ka wikiwiki o ka hana ʻana me ka ʻole o ka hoʻohālikelike ʻana i ka maikaʻi.
I ka hopena, hōʻike ka e-beam PVD i kahi lele hou i ka ʻenehana uhi. ʻO kona hiki ke hāʻawi i ka maikaʻi kūʻokoʻa, versatility a me nā hiʻohiʻona kaiapuni e lilo ia i hopena kaulana i nā ʻoihana. Ke hoʻomau nei ka nui o ka R&D i ka ʻenehana, manaʻo mākou e lilo ka e-beam PVD i mea maʻamau i ka hana ʻana, ka hoʻokele ʻana i nā mea hou a me ka hana ʻana i nā huahana maikaʻi.
