Hiki iā PVD

ʻO ka uhi ʻana o PVD (physical vapor deposition), i ʻike ʻia hoʻi ʻo ka uhi kiʻiʻoniʻoni lahilahi, he hana ia e hoʻoheheʻe ʻia ai kahi mea paʻa i loko o kahi ʻōpala a waiho ʻia ma ka ʻili o kahi ʻāpana.ʻAʻole naʻe kēia mau ʻāpana metala wale nō.Akā, waiho ʻia nā mea hoʻohui i ka atom e ka atom, e hana ana i kahi ʻāpana lahilahi, hoʻopaʻa ʻia, metala a metala-seramika paha e hoʻomaikaʻi nui ai i ke ʻano, ka lōʻihi, a me ka hana o kahi ʻāpana a huahana paha.

No ka hana ʻana i kahi uhi PVD e hoʻohana ʻoe i ka mahu metala hapa ionized.Hoʻopili ia me kekahi mau kinoea a hana i kahi kiʻiʻoniʻoni lahilahi me kahi ʻano kikoʻī ma ka substrate.ʻO nā ʻano hana maʻamau ka sputtering a me ka cathodic arc.

I ka sputtering, hana ʻia ka mahu e kahi pahu pahu metala i hoʻopaʻa ʻia me nā ion kinoea ikaika.Hoʻohana ʻia ke ʻano Cathodic arc i nā hoʻokuʻu ʻana i ka pahu pahu e hahau i ka pahu metala a e hoʻopau i ka mea.Hana ʻia nā kaʻina hana PVD āpau ma lalo o nā kūlana vacuum kiʻekiʻe.ʻO ka mahana hana maʻamau no nā uhi PVD ma waena o 250°C a me 450°C.I kekahi mau hihia, hiki ke waiho ʻia nā pale PVD ma nā mahana ma lalo o 70 ° C a i ʻole 600 ° C, ma muli o nā mea substrate a me nā ʻano i manaʻo ʻia i ka noi.

Hiki ke waiho ʻia nā uhi e like me ka mono-, multi- a me nā papa helu.ʻO nā kiʻi ʻoniʻoni hou loa he nanostructured a superlattice nā ʻano like ʻole o nā ʻāpana multi-layered, e hāʻawi ana i nā waiwai i hoʻonui ʻia.Hiki ke hoʻopaʻa ʻia ke ʻano o ka uhi e hana i nā waiwai i makemake ʻia e pili ana i ka paʻakikī, adhesion, friction etc.

Hoʻoholo ʻia ka koho pani hope loa e nā koi o ka noi.Aia ka mānoanoa o ka uhi mai ka 2 a hiki i ka 5 µm, akā hiki ke ʻano lahilahi e like me nā haneli nanometer a i ʻole ka mānoanoa e like me 15 a ʻoi aku paha µm.Loaʻa nā mea substrate i nā kila, nā metala non-ferrous, tungsten carbide a me nā plastic i hoʻopaʻa mua ʻia.ʻO ke kūpono o ka mea substrate no ka uhi ʻana o PVD i kaupalena wale ʻia e kona kūpaʻa i ka mahana deposition a me ka conductivity uila.

ʻO nā ʻili kiʻiʻoniʻoni ʻoniʻoni hoʻonaninani he mau lōʻihi: hāʻawi lākou i ka ʻaʻahu maikaʻi loa a me ka pale ʻana i ka corrosion.Eia naʻe, ʻaʻohe o lākou mau ʻano tribological like me nā kiʻiʻoniʻoni ʻoi aku ka mānoanoa i hoʻolālā ʻia no nā noi ʻaʻahu.No ka mea ʻo ka hana nui o ka uhi ʻana ʻo ia ka hana ʻana i nā mea hoʻonaninani a ʻaʻole tribological, ʻo ka mānoanoa kiʻiʻoniʻoni no ka hapa nui o nā kiʻi ʻoniʻoni ʻoi aku ka liʻiliʻi ma mua o 0.5 µm.

1. Ka lōʻihi

ʻO kekahi o nā pōmaikaʻi nui o ka PVD Plating Process ʻo ia ka lōʻihi o ka lōʻihi.ʻO nā ʻano hana kuʻuna, e like me ka electroplating, e hoʻohana i kahi ʻāpana lahilahi o ka metala hiki ke hemo maʻalahi.ʻO ke kaʻina hana PVD, ma ka ʻaoʻao ʻē aʻe, hana i kahi uhi paʻa paʻa i kemika a me ka pale ʻana.He koho maikaʻi kēia no nā huahana i hōʻike ʻia i nā kūlana koʻikoʻi, e like me nā lako waho a me nā lako lumi ʻauʻau.

2. Pili kaiaola

ʻO ka PVD Plating Process kekahi mea ʻoluʻolu no ka hoʻohana ʻana i nā kemika liʻiliʻi a hoʻohua i ka ʻōpala liʻiliʻi i hoʻohālikelike ʻia i nā ʻano plating kuʻuna.ʻO kēia ka mea i koho hoʻomau a pili i ke kaiapuni no nā mea kālepa e ʻimi nei e hōʻemi i kā lākou kapuaʻi kalapona.

3. Hoʻopau kūlana kiʻekiʻe

He mea kūpono ka PVD Plating Process no ka hana ʻana i kahi hoʻopau kiʻekiʻe kiʻekiʻe e kūlike a kūlike.Hoʻopuka ke kaʻina hana i kahi hoʻopau ʻoluʻolu, e like me ke aniani e ʻoluʻolu a hoʻohui i ka waiwai i ka huahana hope.He mea koʻikoʻi kēia no nā huahana i hoʻohana ʻia i nā noi kiʻekiʻe, e like me nā wati nani a me nā mea nani.

4. Hoomalu Haahaa

ʻO nā huahana i loaʻa i ka PVD Plating Process he maʻalahi ka mālama ʻana a koi aku i ka mālama liʻiliʻi.ʻAʻole ʻeleʻele ka ʻili, ʻo ia hoʻi, ʻaʻole pono ia i ka polishing e mālama i kona helehelena.He koho maikaʻi kēia no nā huahana i hoʻohana pinepine ʻia, e like me nā mea ʻoki a me nā lako puka.

Loaʻa i ka PVD Plating Process ka nui o nā noi ma nā ʻoihana like ʻole.Eia kekahi mau laʻana o ka hoʻohana ʻana i kēia kaʻina hana e hoʻomaikaʻi i ka hana a me ke ʻano o nā huahana like ʻole:

1. ʻOihana Kaʻa

Hoʻohana maʻamau ʻia ka PVD Plating Process i ka ʻoihana kaʻa e hana i kahi ʻano hoʻopau a me nā uhi no nā ʻāpana like ʻole o ke kaʻa.No ka laʻana, hiki ke hoʻohana ʻia e hana i kahi hoʻopau chrome ʻeleʻele no nā huila kaʻa a i ʻole ka hoʻopau nickel brushed no nā ʻoki kūloko.ʻO ke kūpaʻa kiʻekiʻe a me ke kūpaʻa kemika o ke kaʻina hana PVD e lilo ia i koho kūpono no nā huahana pono e kū i nā kūlana ʻino a me nā lole a me nā waimaka i kēlā me kēia lā.

2. ʻOihana Uila

Loaʻa ka ʻoihana uila mai ka PVD Plating Process, i hoʻohana ʻia e hana i nā uhi no nā huahana e like me nā pale kamepiula, nā papa kaapuni, a me nā pahu kelepona.Kōkua ke kaʻina hana i ka hoʻomaikaʻi ʻana i ka hana, ka lōʻihi, a me ka nani o kēia mau huahana, e ʻoi aku ka nani o nā mea kūʻai.
