Meiao kicheni & yekugezera PVD maitiro akaziviswa
2024-03-21
PVD (Mumuviri Vaporition) tekinoroji yedanho rekurapa rekurapa rinoitwa pasi pepasi pemukati medu. substrate yekuumba firimu rakatetepa neinokosha basa. Iyo tekinoroji yakakamurwa kuita zvikamu zvitatu zvikuru: Vacuum Equaporation Coating, vacuum inosvetukira kuunganidza uye vaisanganisira nzira dzakasiyana-siyana dzekubuda, dzakasvina uye magetsi arc.
MuPVD maitiro, danho rekutanga nderekusvitsa zvinhu zvekutarisa, uko maatomu ekutarisa, mamorekuru kana kuti ion anogadzirwa nekudziya kwezvinhu tembiricha yekuvharira Aya magasi anobva atama uye akaisa pane iyo substrate nzvimbo munzvimbo yekuvhara yekugadzira firimu rakatetepa. Maitiro ese ari nyore, kusasvibisa uye zvakasvibiswa zvine hushamwari, uye kuumbwa kwemafirimu kwunifomu uye kwakasimba, nekusungwa kwakasimba kune substrate.
PVD tekinoroji inoshandiswa zvakanyanya muEerospace, zvemagetsi, Optics, michina, inogona kugadziriswa, ichisimbisa, photositive, piezoelectric, maginitive, superconductivity uye humwe hunhu yefirimu. Nekuvandudzwa kweTekinoroji yepamusoro uye maindasitiri, PVD tekinoroji inogara ichisimudzira, uye akawanda matsva emhando yepamusoro-matsvina exttery akaenzana arc kusimudzira kukura kwehunyanzvi.
Fekitori yedu inoshandisa mhando yekutanga yevacuum equaporation yekubatanidza, uye maitiro ese ekuunganidza uku kuchatsanangurwa zvakadzama pazasi.
VaCuum Equaporation Coating ndeimwe yeiyo yekare uye inonyanya kushandiswa kushandiswa nzira muPVD tekinoroji. Muchiitiko ichi, chinangwa chekutanga chinotanga kupisa kune tembiricha yekuvhura, ichiita kuti vheji uye vasiye mvura kana nzvimbo yakasimba. Pashure pacho, izvi zvinhu zvidiki zvinogara zvichitama kune iyo substrate nzvimbo mune vacuum uye pakupedzisira dhipoziti yekuumba firimu rakatetepa.
Kuti uwane maitiro aya, sosi yekuvira inoshandiswa kupisa zvinhu zvekuisa pakuratidzira tembiricha. Pane sarudzo dzakasiyana-siyana dzekushandiswa kwemapepa, kusanganisira kuramba kupokana, matanda emagetsi, laser matanda, uye vamwe. Pane izvi, kuparadza everation zvinyorwa uye elektron beam euter everation zvinyorwa zvinonyanya kuitika. Pamusoro pekunaka kwemagetsi everation, pane zvakare zvimwe zvakakosha-zvinongedzo zvekubuda, zvakadai seyakawandisa-frequency indiction kupisa, arc kupisa, kupenya kupisa uye zvichingodaro.
Iyo yekutanga maitiro kuyerera kwevacuum everation yekuvhara ndeye inotevera:
1.Pre-Plating kurapwa: kusanganisira kuchenesa uye kunyepedzera. Kuchenesa matanho kunosanganisira kuderera kwekuchenesa, kumakemikari Sol solching
2.Furnurance Kurodha: Iyi nhanho inosanganisira kucheneswa kweiyo vacuum kamuri, kuchenesa hutsinye hurefu, pamwe nekuisa muvepo uye kumisikidza iyo plating lab cast coat kadhi.
3.VaCucuum Exction: Chekutanga, Dhizaina Kupomba inoitwa Mushure mekupokana kwakaringana, vhura vharuvhu rakakwira uye shandisa iyo yakashata pombi yekupomba iyo vacuum kune kumashure kusimuka kwezasi kwe0.006pa.
4.Basa: zvikamu zvakarongedzwa zvinopiswa kune iyo yekudziya yaunoda.
5.Ndinokurwa Bombardment: Ion Bombardment inoitwa neCuum Level of anenge 100 pa -.1 PO, uchishandisa isina kunaka nzvimbo kusvika ku1 kv, uye Bombardment inoitwa kwemaminitsi mashanu kusvika makumi matatu maminitsi.
6.PRE-Melting: Gadzirisa iyo yazvino kuti pre-inonyungudutsa iyo yekuisa zvinhu uye degas kweminiti 1 kusvika pamaminitsi maviri.
7.Evipatiration deposition: Gadzirisa iyo everation yazvino sezvinodiwa kusvika pakupedzisira kwekupedzisira nguva yasvika.
8.Coling: kutonhora zvikamu zvakarongedzwa kune imwe tembiricha mune yekuvhara imba.
9.Discharge: Mushure mekubvisa zvikamu zvakarongedzwa, pombi nzvimbo yekuvhara kusvika 0.1 pa, wozotonhorera pombi inobvumirwa, uye pakupedzisira kuvhara pombi yekugadzirisa uye mvura inotonhora.
10.Post-kurapwa: ita post-kurapwa kwebasa senge kushandisa jasi repamusoro.
