Halayen Plasma a cikin Bayanin Cathodic Arc

Nazarin Fasaha daga Ra'ayoyin Tsarin Aiki da Kayan Aiki

Ma'ajiyar baka ta CathodicN an san shi sosai a matsayin fasahar PVD mai yawan ionization wadda ke iya samar da rufin da ke da yawa, mai mannewa sosai, kuma mai tauri sosai.
A cikin wannan tsari akwai ƙwayar plasma ta musamman da aka samar ta hanyar fitar da iskar shaka ta cathodic, wacce halayenta suka bambanta ta da magnetron sputtering da sauran dabarun PVD.

Fahimtar halayen plasma a cikin tsarin arc na cathodic yana da mahimmanci don sarrafa tsarin shafi, aiki, da kwanciyar hankali na tsari na dogon lokaci.

1. Asalin Plasma na Cathodic Arc

A cikin ajiyar arc na cathodic, ana samar da plasma a wuraren da aka gano ƙwayoyin cuta masu ƙananan ƙwayoyin cuta da aka samar a saman da aka nufa lokacin da aka fara fitar da arc mai ƙarfin lantarki mai ƙarancin wutar lantarki.

Babban abubuwan da ke haifar da spots na cathode sune:

1. Yawan kwararar wutar lantarki ta gida mai yawa (10⁶–10⁸ A/cm²)

2. Zafin jiki mai matuƙar girma

3. Ƙarfin fashewar abu mai sauri na cathode

Wannan tsari yana samar da sinadarin plasma wanda ya ƙunshi galibin abubuwan da aka yi niyya da ionized, maimakon ƙwayoyin halitta marasa tsaka tsaki.

2. Babban Digiri na Ionization: Halaye Mai Ma'ana

Ɗaya daga cikin mahimman abubuwan da ke cikin plasma na cathodic arc shine babban ionization nasa.

Yawan ionization na nau'in ƙarfe na iya wuce kashi 70-90% kuma babban adadin ions ana ninka su (M²⁺, M³⁺)

Wannan babban matakin ionization yana ba da damar:

1. Ƙarfin hulɗar ion-substrate

2. Inganta yawan fim

3. Mannewa mai kyau na shafi ko da a yanayin zafi mai ƙarancin zafi

Daga mahangar injiniyanci, babban ionization yana ba da faffadan tsari mai ƙarfi, musamman ga rufin da ke da tauri da kariya.

3. Ƙarfin Ion Mai Girma da kuma Alkibla

Plasma na Cathodic arc yana nuna babban ƙarfin ion na ciki, yawanci yana farawa daga goma zuwa fiye da volts na electron ɗari.

Sakamakon wannan sinadarin plasma mai kuzari ya haɗa da:

1. Ingantaccen kunnawa da tsaftacewa a saman

2. Ƙara ƙarfin motsin ɗan adam akan substrate

3. Samar da tsarin fim mai yawa, mai laushi ko mara tsari

Idan aka haɗa shi da son zuciya, za a iya daidaita makamashin ion daidai don daidaitawa:

1. Yawan fim

2. Kula da damuwa da ya rage

3. Mannewa a shafi

Wannan ikon sarrafawa babban fa'ida ne na tsarin baka na cathodic a aikace-aikacen masana'antu.

4. Yawan Jini da Sifofin Sufuri na Jini

Idan aka kwatanta da sauran plasmas na PVD, plasma na cathodic arc yana nuna:

1. Yawan sinadarin plasma mai yawa sosai

2. Ƙarfin faɗaɗawar jini mai ƙarfi da kansa daga wurin cathode

Jigilar plasma tana da tasiri ta hanyar: Arc current; Filin sitiyari na Magnetic; Tsarin ɗakin taro;

Jagorar plasma mai kyau tana tabbatar da: Kauri mai kama da juna; Daidaiton ajiyar kaya; Halayen shafi masu daidaito a cikin rukuni-rukuni

5. Manyan Kwayoyin Halitta: Kalubalen Jini na Musamman

Wani siffa ta musamman ta plasma na cathodic arc shine samar da macroparticles a lokaci guda (ɗigo-ɗigo).

Waɗannan ƙwayoyin da suka narke ko masu tauri sun samo asali ne daga: Fitar da abubuwa masu fashewa a wuraren da ke ɗauke da cathode; Macroparticles na iya yin mummunan tasiri ga:; Tsananin saman; Ingancin gani; Ayyukan Tribological

Don magance wannan, tsarin masana'antu galibi suna haɗawa:

Tsarin plasma mai tacewa irin na Magnetic ko bututu

Ingantaccen tsarin tuƙi na cathode

Fasahar baka mai tacewa tana ba da damar riƙe fa'idodin ionization mai yawa yayin da take rage gurɓatar ƙwayoyin cuta sosai.
