Ka Manaʻo o ka ʻenehana paʻa paʻa: nā loina a me ka hoʻohana ʻana

I nā ʻōnaehana hana hou, ʻoi aku ka hilinaʻi o ka huahana, ka pono o nā lako, a me ke ola lawelawe ʻāpana i ka holomua o ka ʻenekinia honua. Ma ke ʻano koʻikoʻi o ka mālama ʻana i ka ʻili, ua hoʻohana nui ʻia ka ʻenehana uhi paʻakikī ma waena o nā ʻoihana e like me ka ʻoki ʻana i nā mea hana, nā ʻōpala, nā ʻāpana kī automotive, a me nā huahana 3C. He mea hoʻohana nui ia no ka hoʻonui ʻana i ka lōʻihi, hilinaʻi, a me ka hana holoʻokoʻa.

No.1 wehewehe ʻenehana a me ke kūlana hana

ʻO ka "paʻa paʻa paʻa" e pili ana i nā kiʻiʻoniʻoni lahilahi hana i waiho ʻia ma kahi substrate ma o ka Physical Vapor Deposition (PVD) a i ʻole Chemical Vapor Deposition (CVD). He mānoanoa kēia mau uhi mai ka 1 a hiki i ka 5 μm, me ka microhardness kiʻekiʻe (> 2000 HV), ka haʻahaʻa haʻahaʻa o ka friction (<0.3), ke kūpaʻa wela maikaʻi loa, a me ka adhesion interfacial ikaika - e hoʻonui nui i ke ola lawelawe a me nā palena hana o nā mea substrate.

Ma mua o ka hana ʻana ma ke ʻano he "uhi" ili, ua hana ʻia nā ʻili paʻa me nā hale papa i hoʻopaʻa ʻia, nā mea i koho ʻia, a me nā mīkini hoʻopili substrate-coating adhesion. ʻO kēia ka mea e hiki ai i nā uhi ke kū i nā kūlana hana paʻakikī i ka manawa hoʻokahi e hāʻawi ana i ke kūpaʻa ʻaʻahu, ke kūpaʻa wela, a me ka pale corrosion.

No.2 Nā Kumu Hana o ka Paʻa Paʻa

Hoʻokomo mua ʻia nā uhi paʻa me ka hoʻohana ʻana i ʻelua mau ʻano nui: Physical Vapor Deposition (PVD) a me Chemical Vapor Deposition (CVD).

1. Hoʻomoe ʻana i ka mahu kino (PVD)

ʻO ka PVD kahi kaʻina hana maʻemaʻe kahi e hoʻoheheʻe ʻia ai ka mea uhi, ka sputtering, a i ʻole ka ionization a waiho i kahi kiʻiʻoniʻoni lahilahi ma ka ʻili substrate. ʻO ka hana maʻamau e pili ana:

ʻO ka hoʻoheheʻe ʻana a i ʻole ka sputtering

ʻO ka lawe ʻana i ka ʻāwīwī: Neʻe nā ʻātoma/iona i loko o kahi kaiapuni

Hoʻokumu kiʻiʻoniʻoni: Condensation a me ka ulu ʻana o kahi uhi paʻa ma ka substrate

Aia nā ʻenehana PVD maʻamau:

Hoʻohu wela

Mākēneki Sputtering

Ahu Ion Coating

2. Hoʻomoe ʻana i ka mahu (CVD)

Hoʻokomo ʻia ka CVD i ka hoʻokomo ʻana i nā precursors kinoea ma nā mahana kiʻekiʻe e hana kemika ma ka ʻili substrate, e hana ana i kahi uhi paʻa. He kūpono kēia ʻano no nā uhi paʻa wela e like me TiC, TiN, a me SiC.

Nā hiʻohiʻona nui:

Hoʻopili ikaika i ka substrate

Hiki ke hana i nā uhi mānoanoa

ʻO nā mahana hana kiʻekiʻe e koi ana i nā substrate pale wela

No.3 No

I loko o nā ʻoihana ʻenehana e pili ana i nā ukana kiʻekiʻe a me ka hana kiʻekiʻe-frequency, hoʻopili ʻia nā ʻāpana i ka friction, corrosion, a me ka haʻalulu wela. Hoʻokumu ʻia nā ʻili paʻa i kahi papa pale paʻa kiʻekiʻe, haʻahaʻa haʻahaʻa, a me ka thermally stable e hoʻonui nui ai i ka hana ʻana a me ke ola ʻana:

ʻO nā mea hana ʻoki: Hoʻomaikaʻi maikaʻi nā uhi e like me TiAlN a me AlCrN i ke kūpaʻa wela a me ka hoʻohana ʻana i ka hana, hoʻonui i ke ola mea hana ma 2 a 5 mau manawa, e hōʻemi ana i nā hoʻololi mea hana, a me ka hoʻomaikaʻi ʻana i ka machining.

Molds and Punches: TiCrAlN and AlCrN coatings hōʻemi i ka ʻaʻahu, ka ʻāʻī, a me ka māhā luhi wela—e hoʻomaikaʻi i ke ola lawelawe ʻana, ka maikaʻi o ka hapa, a me ka hōʻemi ʻana i ka wā hoʻomaha.

Nā ʻĀpana Kaʻa: DLC (Diamond-Like Carbon) i uhi ʻia ma nā ʻāpana e like me nā tappets, nā piston pins, a me nā mea hoʻokiʻekiʻe valve e hoʻohaʻahaʻa i ka friction a me nā helu ʻaʻahu, e hoʻolōʻihi i nā manawa pani, a hoʻomaikaʻi i ka pono wahie.

3C Consumer Electronics: ʻO TiN, CrN, a me nā mea hoʻonani paʻakikī ʻē aʻe ma nā hale kelepona a me nā bezels pahupaʻikiʻi e hāʻawi i ka pale ʻana a me ka pale ʻana i ka corrosion ʻoiai e hoʻopaʻa ana i ka pau metala no ka hoʻonui ʻana i ka ʻike mea hoʻohana.

NO.5 Zhenhua Vacuum's Hard Coating Deposition Solutions: E hiki ai

Hana Hana Kiʻekiʻe

No ka hoʻokō ʻana i ka piʻi ʻana o ka noi no nā pale hana kiʻekiʻe ma waena o nā ʻoihana, hāʻawi ʻo Zhenhua Vacuum i nā ʻōnaehana deposition paʻakikī paʻakikī e hōʻike ana i ka maikaʻi deposition kiʻekiʻe a me ka hoʻohālikelike ʻana i nā kaʻina hana-kūpono no ka hana pololei ʻana i nā mold, nā mea hana ʻoki, a me nā ʻāpana kaʻa.

Nā Pōmaikaʻi Nui:

ʻO ka kānana plasma arc kūpono no ka hoʻemi ʻana i ka macroparticle

ʻO nā uhi Ta-C kiʻekiʻe e hui pū ana i ka pono a me ka lōʻihi

ʻO ka paʻakikī kiʻekiʻe loa (a hiki i ka 63 GPa), ka helu haʻahaʻa haʻahaʻa, a me ke kū ʻana o ka corrosion.

Nā ʻano uhi kūpono:

Kākoʻo ka ʻōnaehana i ka waiho ʻana o nā uhi wela kiʻekiʻe, paʻakikī loa e like me AlTiN, AlCrN, TiCrAlN, TiAlSiN, CrN, a me nā mea ʻē aʻe - hoʻohana nui ʻia i nā mold, nā mea hana ʻoki, nā punches, nā ʻāpana kaʻa, a me nā pistons.
