Litlhahiso tsa indasteri bakeng sa ho seha lipoleiti tsa aluminium ka pulse

Bakeng sa ho seha ha laser ea pulse ea aluminium, karolo ea bohlokoa ke ho laola ka nepo tlhahiso ea pulse ea laser (maqhubu, potoloho ea mosebetsi, jj.) le ho futhumatsa thepa nako le nako ho ntlafatsa tlhahiso ea mocheso, e le ho leka-lekanya boleng ba ho seha le katleho tlas'a reflectivity e phahameng le conductivity ea mocheso ea aluminium.

Liparamente tsa bohlokoa tsa ts'ebetso le litlhahiso tsa ntlafatso

Tse latelang ke dikgothaletso tsa ho seha dipoleiti tsa aluminium ho ya ka botenya bo fapaneng, tse akaretswang ho tswa dipatlisisong tsa thuto:

Maikemisetso a Ts'ebetso

Ho seha ha boleng bo holimo (fokotsa ho fanyeha ha lesoba, ntlafatsa qetello ea karolo)

• Botenya bo sebetsang: botenya bo mahareng (mohlala, 4mm)
• Litlhahiso tsa bohlokoa tsa paramethara:
• Mokhoa oa laser: Mokhoa oa ho otla o khothaletsoa
• Khase e thusang: Nitrojene kapa Argon lia khothaletsoa
• Lintlha tsa bohlokoa: eketsa khatello ea moea e thusang ho ntlafatsa matla a ho foka ha slag; laola ho kenya mocheso ka laser ho qoba ho qhibiliha ho feteletseng.

Ho seha poleiti ka bokgabane bo phahameng/botenya (ho lelekisa lebelo kapa ho seha poleiti e teteaneng)

• Botenya bo sebetsang: poleiti e mahareng le e boima (mohlala, 10-15mm)
• Litlhahiso tsa bohlokoa tsa paramethara:
• Mokhoa oa laser: o ka sebelisa maqhubu a tsoelang pele kapa potoloho e phahameng ea mosebetsi
• Khase e thusang: oksijene e ka lekoa
• Lintlha tsa bohlokoa: Karabelo ea oksijene e tsoang kantle ho thermal e ka eketsa matla le ho ntlafatsa bokhoni ba ho seha lipoleiti tse teteaneng; empa karolo e tla oxidation le ho ba thata, 'me ho hlokahala ts'ebetso e latelang.

Ho seha ka nepo e phahameng/leqephe (ho sebelisoa masimong a nepahetseng joalo ka sefofane)

• Botenya bo sebetsang: poleiti e tšesaane (mohlala, 0.5-2mm)
• Litlhahiso tsa bohlokoa tsa paramethara:
• Mokhoa oa laser: mokhoa oa ho otla ha pelo ka maqhubu a phahameng oa khothaletsoa
• Khase e thusang: Nitrojene e kgothaletswa
• Lintlha tsa bohlokoa: tšebeliso ea lebelo le phahameng la ho seha le khatello e thusang e loketseng; laola mocheso ho fokotsa sebaka se amehileng ke mocheso (se ka laoloa ka tlase ho 20 m).

Kakaretso ea li-parameter tsa boleng bo holimo (mohlala, motsoako oa aluminium oa 4mm 2219)

E le ho fihlella maemo a ho seha a boemo ba 1 (ho fokotsa ho leketlisa ha slag le ho se be le makukuno a tlase), phuputso e fumane hore mefuta e metle ya di-parameter ke:

• Matla a laser:>4.5 kW
• Lebelo la ho seha: 3-4 m/min
• Khatello ea moea e thusang: 1.3 MPa

Liphephetso tsa Bohlokoa le Litharollo tse Reriloeng

Liphephetso le litharollo tse kholo tsa ho seha aluminium ke tse latelang:

1. Ho bonahatsa ho hoholo ha khanya

• Bothata: Aluminium e na le khanya e matla holim'a laser, haholo-holo laser ea fiber e haufi le infrared, le tšebeliso e tlase ea matla.
• Tharollo: Sebelisa laser e nang le mokhoa oa "khahlanong le ho bonahatsa"; sebelisa pulse e nang le matla a mangata ho qhaqha thepa mohatong oa pele oa ho seha, 'me ho bonahatsa ho tla fokotseha ka mor'a hore lesoba la pele le thehoe.

2. Ho tsamaisa mocheso ka potlako le ho leketlisa ha slag habonolo

• Bothata: Mocheso o fela kapele, 'me tšepe e qhibilihisitsoeng e ka tlase ho sehiloeng e ea kopana ho etsa lerōle leo ho leng thata ho le tlosa.
• Tharollo: Ha e bapisoa le laser e tsoelang pele, laser ea pulse e ka laola ho kenella ha mocheso ka nepo haholoanyane; Eketsa khatello ea khase e thusang (joalo ka ≥ 1.3MPa), ntlafatsa matla a ho shear a moea ho foka slag; Ntlafatsa boemo ba ho tsepamisa maikutlo, hangata ka tlase ho bokaholimo ba poleiti.

3. Boleng ba karolo ea ho khaola le litlhoko tse latelang tsa ts'ebetso

• Bothata: Karolo ea ho seha e tla etsa lera le qhibilihisitsoeng hape. Haeba ho hlokahala ho tjheseletsa ka mor'a moo, e tla ama masoba a tjheseletsa.
• Tharollo: Haeba ho hlokahala ho tjheseletsa ka mora ho seha, tshebetso e lokela ho laolwa ka thata, mme botenya ba lera la ho qhibilihisa seam ya ho seha bo lokela ho laolwa ka tlase ho 136μm ho fokotsa ka katleho masoba a tjheseletsa.

Lethathamo la lintlha tsa bohlokoa tsa ts'ebetso ea indasteri

• Khetho ea khase:ho phehella ho seha ha boleng bo holimo ho sa keneng ka oksideishene (haholo-holo tlhoko e latelang ea ho tjheseletsa), etelletsa pele naetrojene kapa argon e hloekileng haholo. Oksijene e ka hlahlojoa ha ho ntse ho phehelloa botenya le lebelo la ho seha 'me oxidation ea karolo e se bothata.
• Tatellano ea ho lokisa liphoso tsa paramethara:Ho kgothaletswa ho lokisa di-variable tse ding le ho lokisa diphoso ka tatellano ena: sebaka sa ho tsepamisa maikutlo → mofuta wa kgase e thusang le kgatello → matla a laser → lebelo la ho seha → di-parameter tsa pulse (haeba ho sebediswa mokgwa wa pulse).
• Lisebelisoa le polokeho:ho netefatsa hore laser e na le bokhoni ba ho sebetsana le thepa e bonahatsang haholo; Ha ho sehoa poleiti ea aluminium, ho phatloha ha tlhase ho matla haholo. Hoa hlokahala ho netefatsa hore sistimi ea ho tlosa lerōle e sebetsa hantle 'me lisebelisoa le basebetsi ba sirelelitsoe.
• Ho khaola le ho hlahloba teko:Ho seha ha teko ho lokela ho etswa pele ho seha ka semmuso. Bakeng sa tlhahlobo ya boleng, ka kopo sheba: ho shebella ka mahlo ha slag e leketlileng tlase; ho kgopama ha karolo ya ho lemoha mokgwa wa ho kopana; tekanyo ya microscope ya botenya ba lera le qhibilihisitsweng hape (haeba ho na le ditlhoko tse hodimo).

Kakaretso le Litlhahiso tsa ho Qetela

Karolo ea mantlha ea poleiti ea aluminium ea ho itšeha ea laser e nang le pulsed faeba ke"Taolo e nepahetseng ea mocheso"Tsela e latelang e kgothaletswa:

1. Ntho ea bohlokoa ka ho hlaka:pele fumana hore na sepheo sa hau sa mantlha ke boleng ba karolo, katleho ea ho seha kapa ts'ebetso e latelang ea ho tjheseletsa.

2. Ho ea ka botenya ba li-parameter tsa mantlha:sheba tafole e fetileng, ho latela botenya le bohlokoa ba poleiti ea aluminium ea hau, fumana mokhoa oa pele oa laser le mofuta oa khase.

3. Ho lokisa liphoso le netefatso e ntle:Ho lokisa liphoso hantle ho etsoa ho potoloha khatello ea moea e thusang le lebelo la ho khaola, 'me netefatso ea ho khaola teko e etsoa ka tieo.
