Ka hoʻohana ʻana o PVD a me CVD i ka ʻoihana lako

PVD (hoʻoheheʻe kino kino): hoʻohana ʻia ke ʻano kino (e like me ka evaporation, sputtering, etc.) e hoʻoheheʻe i ka mea i uhi ʻia ma ka ʻili substrate a waiho i loko o kahi papa uhi.ʻO ke kaʻina hana o ka hoʻohana ʻana i ke kaʻina hana kino e ʻike ai i ka hoʻoili ʻana a me ka hoʻoili ʻana i nā ʻātoma a i ʻole nā ​​molekole mai ke kumu a i ka ʻili substrate.ʻO kāna hana,ʻo ia ka pīpīʻana i kekahi mau'āpana me nā mea kūikawā (ka ikaika kiʻekiʻe, ke kū'ēʻana, ka hoʻokuʻuʻana i ka wela, ka paleʻana o ka corrosion, a me nā mea'ē aʻe) ma ka matrix me ka hana haʻahaʻa, iʻoi aku ka maikaʻi o ka hana matrix.

ʻO CVD (ka hoʻoheheʻe ʻana i ka mahu kemika): kahi ʻano o ka hoʻoheheʻe ʻana i ke kinoea ma ka ʻili o ka mea matrix a hana i kahi papa uhi.He ʻenehana kaʻina hana ia e hana kemika nā mea reactive ma lalo o nā kūlana kinoea e hana i nā mea paʻa, i waiho ʻia ma ka ʻili o ka matrix paʻa wela, a laila hoʻomākaukau ʻia nā mea paʻa.No ke kaʻina hana hoʻoili kinoea ma ka ʻāpana atomic.

ʻO ka CVD a i ʻole PVD kahi ʻano uhi e like me ka nickel plating, plating gula a me ka zinc plating, ʻo ka hana o ka uhi ke hoʻonui i ka pale ʻana a me ka pale ʻana i ka corrosion.

Ka ʻokoʻa ma waena o PVD a me CVD:

ʻOi aku ka lahilahi o ka PVD ma mua o CVD, a ʻo ka mānoanoa o ka uhi ʻana o CVD he 10 ~ 20 μm.ʻO ka mānoanoa o ka uhi ʻana o PVD he 3 ~ 5 μM wale nō.ʻO ka mahana mālama o PVD ma kahi o 500 ℃, aʻo ka mahana ma ka umu CVD he 800 ~ 1000 ℃.Hiki ke ʻike ʻia ma muli o ke kiʻekiʻe kiʻekiʻe, he kiʻekiʻe ka CVD i nā koi pale wela no nā mea i mālama ʻia

ʻO CVD ka ʻoi aku ka maikaʻi o ke kaiapuni a me ka pale ʻana i ka lole i kēia manawa.Hiki ke hoʻohana ʻia ma nā ʻano he nui, e like me ka ʻoihana uaki a me ka wati, ʻoihana ʻenehana, ʻoihana kaʻa, ʻoihana hānai a pēlā aku.

Inā makemake kekahi no CVD a i ʻole PVD i nā ʻāpana mīkini CNC, e ʻoluʻolu e kelepona me mākou.Hoʻomaʻamaʻa mākou i nā ʻāpana mīkini cnc, ka huli ʻana o ka cnc, ka mīkini milling cnc, ka mīkini lathing cnc, me 45 mau mīkini cnc i kā mākou hale hana, i loko o 3 axis, 4 axis, 5 axis machine.
