Ke hoʻomau nei ka hana ʻana i kēia manawa i ka hana kiʻekiʻe mai nā ʻāpana, ʻoi aku ka poʻe e hana ana ma lalo o nā kūlana koʻikoʻi e like me ke kiʻekiʻe kiʻekiʻe, ke kaomi kiʻekiʻe, a me ka friction ikaika, ua lilo ka ʻenehana uhi i mea koʻikoʻi. ʻO ka hoʻohana ʻana i nā uhi paʻa paʻa ke kuleana nui i ka hoʻonui ʻana i ka paʻa o ka mea hana, ka pololei o ka mīkini, a me ka hana holoʻokoʻa o ka huahana. ʻO ka PVD (Physical Vapor Deposition) ka ʻenehana lapaʻau ʻili ma ke poʻo o ka hana hou i kēia kahua, e hoʻokau nei i nā holomua i ka ʻenehana uhi.
No.1 He aha ke kaʻina hana PVD?
Hoʻohana ʻia ke kaʻina hana PVD me ka hoʻohana ʻana i nā ʻano hana kino e hoʻololi i nā mea uhi mai kahi kūlana paʻa a i ʻole ka wai i loko o ke kinoea, a laila waiho ʻia ma luna o ka ʻili substrate ma o ka hoʻoheheʻe ʻana i ka mahu e hana i kahi ʻaʻahu, paʻakikī a paʻa. Ke hoʻohālikelike ʻia me ka hoʻoheheʻe ʻana o ka mahu (CVD), ʻo ka pono mua o ka PVD aia i kona hiki ke waiho i nā uhi i nā haʻahaʻa haʻahaʻa, e hoʻomalu pono i ka mānoanoa o ka uhi ʻana a me ka hoʻohui ʻana, a me kona ʻano kūlohelohe a me ka ikehu.
No.2 Pono o ka PVD i ka paa paa
Ma muli o kāna mau pono kū hoʻokahi, ʻike nui ʻia ka ʻenehana PVD i ka hoʻohana ʻana i nā uhi paʻakikī, ʻoi aku ka nui o nā wahi e koi ana i ka paʻakikī kiʻekiʻe, ke kūpaʻa maikaʻi loa, a me ke kūpaʻa ʻana o ka corrosion. ʻO nā pōmaikaʻi koʻikoʻi o ke kaʻina hana PVD:
1. Ultra-kiʻekiʻe paʻakikī a me ke pale ʻana
Hoʻonui nui ka paʻakikī PVD i ka paʻakikī o nā mea. Ma ka waiho ʻana i nā mea e like me TiN (Titanium Nitride), TiAlN (Titanium Aluminum Nitride), a me CrN (Chromium Nitride), hiki i ka paʻakikī o ka uhi ke piʻi i 25GPa-63GPa a i ʻole ke kiʻekiʻe. Hoʻomaikaʻi maikaʻi kēia mau ʻāpana paʻa i ka pale ʻana i ka lole, hoʻemi i ka abrasion o ka ʻili, hoʻonui i ka pale ʻana o ka oxidation, a hoʻonui i ke ola lawelawe o nā mea hana, nā ʻāpana, a me nā mea ʻē aʻe.
2. Kūʻē Kūlana Kiʻekiʻe Kiʻekiʻe
Hōʻike nā pale PVD i ke kūpaʻa kiʻekiʻe kiʻekiʻe, e hoʻolilo iā lākou i mea kūpono no nā ʻāpana i hoʻopaʻa ʻia i ka wela wela a me ka friction kiʻekiʻe a i ʻole ka ʻino kino. No ka laʻana, ʻaʻole hāʻawi wale nā uhi TiAlN i ka paʻakikī ʻokoʻa akā mālama pū nō hoʻi i ka paʻa o ke kūkulu ʻana i nā mahana kiʻekiʻe, e hoʻohana nui ʻia i nā mea hana ʻoki a me nā mole no nā noi mīkini kiʻekiʻe.
3. Haʻahaʻa Friction Coefficient no ka hoʻomaikaʻi ʻana i ka mīkini mīkini
Kōkua ka PVD coatings i ka hoʻokō ʻana i nā coefficient friction ultra-haʻahaʻa, e hōʻemi ana i ka friction material a me ka ʻaʻahu, e hoʻonui ai i ka pono mīkini a me ka maikaʻi o ka ʻili. He mea maikaʻi kēia no ka mīkini pololei a me nā kaʻina ʻoki kiʻekiʻe.
4. Pili kaiapuni a maikaʻi loa
Ke hoʻohālikelike ʻia me nā ʻenehana uhi kuʻuna, ʻaʻole koi ke kaʻina hana PVD i ka nui o nā kemika ʻino, e lilo ia i ʻenehana pili i ke kaiapuni. Hoʻohui ʻia, e hana ana nā mea hana PVD coating i ka hana kiʻekiʻe, e hiki ai ke hoʻopaʻa wikiwiki e hoʻokō i nā koi hana nui.
No.3 No
Hoʻohana nui ʻia nā mīkini PVD Hard Coating no nā uhi paʻakikī i nā ʻoihana e koi ana i ka hana ʻoi aku ka maikaʻi. Aia kekahi mau wahi noi nui:
1. Nā mea hana ʻoki a me nā ʻōpala
Ma ka hana ʻana i nā mea hana a me ka poʻi, ʻoi aku ka nui no ka ʻoki ʻana i nā mea hana i ʻike ʻia i nā wela kiʻekiʻe a me ka friction, hoʻomaikaʻi nui nā uhi PVD i ke kūpaʻa ʻaʻahu, ke kūpaʻa ʻana a me ka paʻakikī. Hoʻohana pinepine ʻia nā uhi TiN i ka hoʻohuli ʻana i nā mea hana, nā mea ʻoki milling, a me nā drills, ʻoiai ʻo TiAlN coatings i hoʻohana nui ʻia i nā noi ʻoki kiʻekiʻe, e hoʻomaikaʻi nui ana i ka pono ʻoki ʻoki a me ke ola lawelawe.
2. Nā ʻāpana kaʻa
No nā ʻāpana ʻenekini kaʻa e like me nā cylinders, pistons, a me nā kīwaha, hāʻawi nā uhi paʻa PVD i ke kūpaʻa kiʻekiʻe kiʻekiʻe a me ka pale ʻana i ka ʻaʻahu, e hōʻemi pono i ka friction, hoʻonui i ke ola o nā mea, a me ka hoʻomaikaʻi ʻana i ka hana kaʻa holoʻokoʻa.
4. Hoʻolauna o Zhenhua FMA0605 PVD Paʻa Paʻa Paʻa
Nā Pono Lako
ʻO ka kānana maikaʻi o nā ʻāpana macro-arc; Hāʻawi nā uhi Ta-C i ka hana kiʻekiʻe a me ka hana kiʻekiʻe.
Loaʻa i ka paʻakikī kiʻekiʻe kiʻekiʻe, nā uhi paʻa paʻa kiʻekiʻe-kūpono i ka wela, ka pānaʻi haʻahaʻa haʻahaʻa, a me ke kūpaʻa ʻino maikaʻi loa. Awelika oolea hiki i 25GPa-63GPa.
Hoʻohana ka cathode i kahi ʻenehana kaʻa ʻelua e hui pū ana i ka coil mua a me ka hoʻopaʻa ʻana i ka magnet mau loa, e hana pū ana me kahi ʻōnaehana etching ion a me kahi ʻāpana ʻekolu-dimensional multi-angle e hoʻokō ai i ka hoʻopaʻa pono.
Hoʻolako ʻia me ka cathodic arc nui-diameter, e hōʻoiaʻiʻo ana i nā waiwai hoʻomaha maikaʻi ma lalo o nā kūlana kiʻekiʻe. ʻO ka wikiwiki o ka neʻe ʻana o ke arc, ʻoi aku ka kiʻekiʻe o ka ionization, a wikiwiki ka deposition. ʻO kēia ka mea e hiki ai i ka waiho ʻana o nā uhi ʻoi aku ka ʻoi aku ka maikaʻi o ka oxidation a me ka hana wela kiʻekiʻe.
Lai o ka noi:
Hiki i nā mea hana ke waiho iā AlTiN, AlCrN, TiCrAlN, TiAlSiN, CrN, a me nā mea ʻē aʻe kiʻekiʻe kiʻekiʻe-kū kūʻē i ka superhard coatings, i hoʻohana nui ʻia i nā mold, nā mea ʻokiʻoki, nā punches, nā ʻāpana automotive, pistons, a me nā huahana ʻē aʻe.
