Kodi ndi zinthu ziti zomwe zimakhudza poizoni wofunikira pakumwa mankhwala a magnetron?

1, Kupanga zinthu zachitsulo pamalo omwe mukufuna
Kodi chigawochi chimapangidwa kuti popanga chigawochi kuchokera pamwamba pa chitsulo pogwiritsa ntchito njira yothira madzi? Popeza kuti kuchitapo kanthu kwa mankhwala pakati pa tinthu ta mpweya tomwe timathira madzi ndi maatomu pamwamba pa chinthucho kumapanga maatomu ophatikizana, omwe nthawi zambiri amakhala a exothermic, kutentha kwa chinthucho kuyenera kukhala ndi njira yochitira, apo ayi kuchitapo kanthu kwa mankhwala sikungapitirire. Pansi pa mikhalidwe ya vacuum, kusamutsa kutentha pakati pa mpweya sikungatheke, kotero kuchitapo kanthu kwa mankhwala kuyenera kuchitika pamwamba pamphamvu. Kuthira madzi kwa chinthucho kumapanga ma composites pamwamba pa chinthucho, pamwamba pa chinthucho, ndi pamwamba pa chinthucho. Cholinga cha kupanga ma composites pamwamba pa chinthucho ndi kuwononga zinthu, ndipo kupanga ma composites pamwamba pa chinthucho kumayamba ngati gwero la maatomu ophatikizana ndipo kumakhala cholepheretsa kupereka maatomu ophatikizana nthawi zonse.

2, Zinthu zomwe zimayambitsa poizoni
Chinthu chachikulu chomwe chimakhudza poizoni wa chinthu chomwe chikufunidwa ndi chiŵerengero cha mpweya wochitapo kanthu ndi mpweya wotulutsa mpweya, mpweya wochuluka wochitapo kanthu umabweretsa poizoni wa chinthucho. Njira yotulutsira mpweya wochitapo kanthu imachitika pamalo otulutsira mpweya pamwamba pa chinthucho, zomwe zimawoneka ngati zaphimbidwa ndi chinthucho kapena chinthucho chimachotsedwa ndikubwezeretsanso pamwamba pa chitsulo. Ngati kuchuluka kwa mpweya wopangidwa ndi chinthucho kuli kwakukulu kuposa kuchuluka kwa mpweya wotulutsa mpweya, malo ophimba mpweyawo amawonjezeka. Pa mphamvu inayake, kuchuluka kwa mpweya wochitapo kanthu komwe kumakhudzidwa ndi kupanga chinthucho kumawonjezeka ndipo kuchuluka kwa mpweya wopangidwa ndi chinthucho kumawonjezeka. Ngati kuchuluka kwa mpweya wochitapo kanthu kumawonjezeka kwambiri, malo ophimba mpweyawo amawonjezeka. Ndipo ngati kuchuluka kwa mpweya wochitapo kanthu sikungasinthidwe pakapita nthawi, kuchuluka kwa mpweya wochitapo kanthu kumawonjezeka sikuchepetsedwa, ndipo njira yotulutsira mpweyawo imaphimbidwanso ndi chinthucho, pamene chinthucho chimaphimbidwa ndi chinthucho, chinthucho chimaphikidwa ndi poizoni kwathunthu.

3, Chochitika cha poizoni wa chandamale
(1) kuchuluka kwa ma ion abwino: pamene poizoni wa chandamale akupezeka, filimu yotetezera imapangidwa pamwamba pa chandamale, ma ion abwino amafika pamwamba pa chandamale cha cathode chifukwa cha kutsekeka kwa chandamale chotetezera. Sichilowa mwachindunji pamwamba pa chandamale cha cathode, koma chimasonkhana pamwamba pa chandamale, ndipo n'zosavuta kutulutsa mpweya wozizira kuchokera ku arc - arcing, kotero kuti kuphulika kwa cathode sikungapitirire.
(2) anode kusowa: pamene cholinga cha poizoni, pansi vacuum chipinda khoma komanso anaikamo zotetezera kutentha filimu, kufika anode ma elekitironi sangathe kulowa anode, mapangidwe anode kusowa chodabwitsa.

4, Kufotokozera kwa thupi za poizoni woopsa
(1) Kawirikawiri, mphamvu ya electron emission ya secondary electron emission ya mankhwala achitsulo imakhala yokwera kuposa ya zitsulo. Pambuyo pa poizoni wa chandamale, pamwamba pa chandamale pali mankhwala achitsulo okha, ndipo pambuyo poti yaphulitsidwa ndi ma ayoni, chiwerengero cha ma elekitironi achiwiri omwe amatulutsidwa chimawonjezeka, zomwe zimapangitsa kuti mpweya ukhale wabwino komanso kuchepetsa kupopera kwa plasma, zomwe zimapangitsa kuti magetsi a sputtering akhale ochepa. Izi zimachepetsa liwiro la sputtering. Kawirikawiri mphamvu ya sputtering ya magnetron sputtering imakhala pakati pa 400V-600V, ndipo poizoni wa chandamale akachitika, mphamvu ya sputtering imachepa kwambiri.
(2) Chiŵerengero cha kupopera kwa chitsulo ndi chala chophatikizika poyamba chimakhala chosiyana, kawirikawiri chiŵerengero cha kupopera kwa chitsulo chimakhala chapamwamba kuposa chiŵerengero cha kupopera kwa chitsulo, kotero chiŵerengero cha kupopera chimakhala chochepa pambuyo pa poizoni wa chala.
(3) Mphamvu yothira mpweya wo ...

5, Mayankho Othana ndi Poizoni Womwe Amagwiritsidwa Ntchito
(1) Gwiritsani ntchito mphamvu yamagetsi yapakati kapena mphamvu ya wailesi.
(2) Gwiritsani ntchito njira yotsekeka yowongolera mpweya wolowa mkati mwa mpweya.
(3) Tsatirani zolinga ziwiri
(4) Yang'anirani kusintha kwa mawonekedwe a chophimba: Musanayambe kupaka, hysteresis effect curve ya poizoni wa cholinga imasonkhanitsidwa kuti mpweya wolowera uzitha kuyendetsedwa patsogolo popanga poizoni wa cholinga kuti zitsimikizire kuti njirayi nthawi zonse imakhala mu mawonekedwe asanafike kutsika kwakukulu kwa kuchuluka kwa mpweya.
