Pamene kupanga zinthu zamakono kukupitilizabe kufunafuna magwiridwe antchito apamwamba kuchokera ku zigawo, makamaka zomwe zimagwira ntchito pansi pa mikhalidwe yovuta kwambiri monga kutentha kwambiri, kuthamanga kwambiri, ndi kukangana kwamphamvu, ukadaulo wophimba zinthu wakhala wofunikira kwambiri. Kugwiritsa ntchito zophimba zolimba kumachita gawo lofunika kwambiri pakulimbitsa kulimba kwa zida, kulondola kwa makina, komanso magwiridwe antchito onse azinthu. Ukadaulo wokonza pamwamba pa PVD (Physical Npor Deposition) uli patsogolo pa zatsopano m'munda uno, zomwe zikuyendetsa patsogolo ukadaulo wophimba zinthu.
Nambala 1 Kodi njira ya PVD ndi chiyani?
Njira ya PVD imaphatikizapo kugwiritsa ntchito njira zakuthupi kuti zisinthe zinthu zophimba kuchokera ku mkhalidwe wolimba kapena wamadzimadzi kukhala mkhalidwe wa gasi, kenako kuziyika pamwamba pa substrate kudzera mu nthunzi kuti zipange chophimba chofanana, cholimba, komanso cholimba. Poyerekeza ndi njira yachikhalidwe yophimba nthunzi (CVD), ubwino waukulu wa PVD uli mu kuthekera kwake koyika zophimba pa kutentha kochepa, kuwongolera bwino makulidwe ndi kapangidwe kake, komanso momwe zimakhalira zosawononga chilengedwe komanso zosagwiritsa ntchito mphamvu zambiri.
Ubwino Wachiwiri wa PVD mu Zophimba Zolimba
Chifukwa cha ubwino wake wapadera, ukadaulo wa PVD umadziwika kwambiri pogwiritsa ntchito zokutira zolimba, makamaka m'malo omwe amafunika kuuma kwambiri, kukana kukalamba bwino, komanso kukana dzimbiri kwambiri. Ubwino waukulu wa njira ya PVD ndi monga:
1. Kulimba Kwambiri ndi Kukana Kuvala
Zophimba zolimba za PVD zimawonjezera kuuma kwa zigawo. Mwa kuyika zinthu monga TiN (Titanium Nitride), TiAlN (Titanium Aluminium Nitride), ndi CrN (Chromium Nitride), kuuma kwa zophimba kumatha kufika 25GPa–63GPa kapena kupitirira apo. Zophimba zolimba izi zimathandizira bwino kukana kuwonongeka, kuchepetsa kusweka kwa pamwamba, kuwonjezera kukana kwa okosijeni, ndikuwonjezera moyo wa ntchito ya zida, nkhungu, ndi zigawo zina.
2. Kukana Kwambiri Kutentha Kwambiri
Zophimba za PVD zimakhala ndi kukana kutentha kwambiri, zomwe zimapangitsa kuti zikhale zabwino kwambiri pazinthu zomwe zimatentha kwambiri komanso kukanda kwambiri kapena dzimbiri la mankhwala. Mwachitsanzo, zophimba za TiAlN sizimangopereka kuuma kwapadera komanso zimasunga kukhazikika kwa kapangidwe kake pa kutentha kwakukulu, zomwe zimapangitsa kuti zigwiritsidwe ntchito kwambiri podulira zida ndi zinyalala pakugwiritsa ntchito makina otentha kwambiri.
3. Koyenera Yochepa Yokangana Kuti Machining Azigwira Bwino Ntchito
Zophimba za PVD zimathandiza kukwaniritsa ma coefficients otsika kwambiri, kuchepetsa kukangana ndi kuwonongeka kwa zinthu, zomwe zimapangitsa kuti ntchito yokonza makina igwire bwino ntchito komanso kuti pamwamba pake pakhale bwino. Izi zimathandiza kwambiri pakupanga makina molondola komanso kudula mwachangu.
4. Yoteteza chilengedwe komanso yogwira ntchito bwino kwambiri
Poyerekeza ndi njira zachikhalidwe zophikira, njira ya PVD siifuna mankhwala ambiri oopsa, zomwe zimapangitsa kuti ikhale ukadaulo wosawononga chilengedwe. Kuphatikiza apo, zida zophikira za PVD zimagwira ntchito bwino kwambiri, zomwe zimathandiza kuti zigwiritsidwe ntchito mwachangu kuti zikwaniritse zofunikira zazikulu zopangira.
Nambala 3 Kugwiritsa Ntchito Magawo a PVD Hard Coating
Makina Opaka Olimba a PVD a zokutira zolimba amagwiritsidwa ntchito kwambiri m'mafakitale omwe amafunikira magwiridwe antchito apamwamba. Magawo ena ofunikira ogwiritsira ntchito ndi awa:
1. Zida Zodulira ndi Zoumba
Pakupanga zida ndi nkhungu, makamaka zida zodulira zomwe zimakhudzidwa ndi kutentha kwambiri komanso kukangana, zokutira za PVD zimathandizira kwambiri kukana kuwonongeka, kukana dzimbiri, komanso kuuma. Zophimba za TiN zimagwiritsidwa ntchito kwambiri potembenuza zida, zodulira mphero, ndi zobowola, pomwe zokutira za TiAlN zimagwiritsidwa ntchito kwambiri podulira mwachangu kwambiri, zomwe zimapangitsa kuti kudula zida kukhale kogwira mtima komanso kukhala ndi moyo wautali.
2. Zigawo za Magalimoto
Pazida zamagalimoto monga masilinda, ma pistoni, ndi ma valve, zokutira zolimba za PVD zimapereka kukana kutentha kwambiri komanso kukana kuwonongeka, zomwe zimachepetsa kukangana, kukulitsa nthawi ya moyo wa zida, komanso kukulitsa magwiridwe antchito agalimoto yonse.
4. Chiyambi cha Zhenhua FMA0605 PVD Hard Coating Equipment
Ubwino wa Zida
Kusefa bwino kwa tinthu tating'onoting'ono ta arc; Zophimba za Ta-C zimapereka mphamvu zambiri komanso magwiridwe antchito apamwamba.
Imakwaniritsa kuuma kwambiri, zokutira zolimba kwambiri zosatentha kwambiri, kukhuthala kochepa, komanso kukana dzimbiri bwino. Kuuma kwapakati kumafika 25GPa–63GPa.
Cathode imagwiritsa ntchito ukadaulo wa ma drive awiri kuphatikiza coil yomwe ili kutsogolo ndi maginito okhazikika, kugwira ntchito limodzi ndi makina ojambulira ma ion ndi chogwirira cha ma angle ambiri cha magawo atatu kuti chikwaniritse bwino kuyika.
Yokhala ndi arc yayikulu ya cathodic, yomwe imatsimikizira kuti kuziziritsa kumakhala bwino kwambiri pakakhala nyengo yamphamvu. Liwiro la kuyenda kwa arc ndi lachangu, kuchuluka kwa ionization ndi kwakukulu, ndipo kuchuluka kwa malo oyikamo ndi kwachangu. Izi zimathandiza kuti zophimba zokhuthala komanso zosalala zikhazikike bwino komanso zotsutsana kwambiri ndi okosijeni komanso kutentha kwambiri.
Chiwerengero cha Ntchito:
Zipangizozi zimatha kuyika AlTiN, AlCrN, TiCrAlN, TiAlSiN, CrN, ndi zina zophimba zolimba kwambiri zomwe sizitentha kwambiri, zomwe zimagwiritsidwa ntchito kwambiri mu nkhungu, zida zodulira, zibowo, zida zamagalimoto, ma pistoni, ndi zinthu zina.
