Ha tlhahiso ea morao-rao e ntse e batla ts'ebetso e phahameng ho tsoa ho likarolo, haholo-holo tse sebetsang tlas'a maemo a feteletseng a kang mocheso o phahameng, khatello e phahameng, le likhohlano tse matla, theknoloji ea ho roala e se e le ea bohlokoa haholo. Tšebeliso ea lirafshoa tse thata li phetha karolo ea bohlokoa ho matlafatsang ho tšoarella ha lisebelisoa, ho sebetsa ka mokhoa o nepahetseng oa mochine, le ho sebetsa ha sehlahisoa ka kakaretso. Theknoloji ea kalafo ea PVD (Physical Vapor Deposition) e ka pele ho boqapi lefapheng lena, e tsamaisang tsoelo-pele ea theknoloji ea ho roala.
No.1 Mokhoa oa PVD ke Ofe?
Ts'ebetso ea PVD e kenyelletsa ho sebelisa mekhoa ea 'mele ho fetola thepa ea ho roala ho tloha sebakeng se tiileng kapa sa mokelikeli ho ea sebakeng sa khase, ebe e li beha holim'a substrate ka ho kenya mouoane ho etsa seaparo se ts'oanang, se thata le se tšoarellang. Ha ho bapisoa le mokhoa oa setso oa ho beha mouoane oa lik'hemik'hale (CVD), melemo ea mantlha ea PVD e itšetlehile ka bokhoni ba eona ba ho beha liphahlo ka mocheso o tlase, ho laola ka nepo botenya le sebopeho sa eona, le tlhaho ea eona e baballang tikoloho le e baballang matla.
No.2 Melemo ea PVD ka Hard Coatings
Ka lebaka la melemo ea eona e ikhethang, theknoloji ea PVD e tsejoa ka ho pharaletseng ha ho sebelisoa liphahlo tse thata, haholo-holo libakeng tse hlokang boima bo phahameng, khanyetso e ntle ea ho roala, le khanyetso e phahameng ea kutu. Melemo ea bohlokoa ea ts'ebetso ea PVD e kenyelletsa:
1. Ultra-high Hardness le Wear Resistance
Liaparo tse thata tsa PVD li ntlafatsa haholo ho thatafala ha likarolo. Ka ho kenya lisebelisoa tse kang TiN (Titanium Nitride), TiAlN (Titanium Aluminium Nitride), le CrN (Chromium Nitride), boima ba ho roala bo ka fihla ho 25GPa-63GPa kapa ho feta. Liaparo tsena tse thata li ntlafatsa ka katleho ho hanyetsa ho apara, ho fokotsa ho senya holimo, ho eketsa khanyetso ea oxidation, le ho lelefatsa bophelo ba tšebeletso ea lisebelisoa, hlobo le likarolo tse ling.
2. E babatsehang Ho hanyetsa Mocheso o Phahameng
Liaparo tsa PVD li bonts'a khanyetso e phahameng ea mocheso o phahameng, e leng se etsang hore e be tse loketseng likarolo tse tlas'a mocheso o feteletseng le khohlano e phahameng kapa ho bola ha lik'hemik'hale. Mohlala, liphahlo tsa TiAlN ha li fane feela ka boima bo ikhethang empa hape li boloka botsitso ba sebopeho maemong a mocheso o phahameng, e leng se etsang hore li sebelisoe haholo ho seha lisebelisoa le hlobo bakeng sa lits'ebetso tsa mochini oa mocheso o phahameng.
3. Low Friction Coefficient bakeng sa Ntlafatso ea Tšebetso ea Machining
Liaparo tsa PVD li thusa ho fihlela li-coefficients tse tlase haholo tsa likhohlano, ho fokotsa likhohlano le ho roala ha thepa, e leng ho ntlafatsang katleho ea machining le boleng ba bokaholimo. Sena se molemo ka ho khetheha bakeng sa ho sebetsa ka mokhoa o nepahetseng le mekhoa ea ho itšeha ka lebelo le phahameng.
4. E Setsoalle le Tikoloho 'me e Sebetsa Haholo
Ha ho bapisoa le mekhoa e tloaelehileng ea ho roala, ts'ebetso ea PVD ha e hloke lik'hemik'hale tse ngata tse kotsi, e leng se etsang hore e be theknoloji e bolokang tikoloho. Ho feta moo, lisebelisoa tsa ho roala tsa PVD li sebetsa ka katleho e phahameng, e nolofalletsang ho beoa ka potlako ho fihlela litlhoko tse kholo tsa tlhahiso.
No.3 Mekhahlelo ea Kopo ea PVD Hard Coating
Mechine ea ho roala ka thata ea PVD bakeng sa ho roala ka thata e sebelisoa haholo liindastering tse hlokang ts'ebetso e phahameng ea holim'a metsi. Libaka tse ling tsa bohlokoa tsa ts'ebeliso li kenyelletsa:
1. Lisebelisoa tsa ho Seha le hlobo
Ha ho etsoa lithulusi le hlobo, haholo-holo bakeng sa lisebelisoa tsa ho seha tse pepesehileng mocheso o phahameng le likhohlano, liphahlo tsa PVD li ntlafatsa haholo ho se sebetse, ho hanyetsa kutu le ho thatafala. Liaparo tsa TiN li atisa ho sebelisoa ho fetola lisebelisoa, li-milling cutters, le li-drill, ha liphahlo tsa TiAlN li sebelisoa haholo lits'ebetsong tsa ho itšeha ka lebelo le phahameng, ho ntlafatsa haholo ts'ebetso ea ho itšeha le bophelo ba ts'ebeletso.
2. Likaroloana tsa Likoloi
Bakeng sa likarolo tsa enjene ea likoloi tse joalo ka lisilindara, li-piston le li-valve, lirafshoa tse thata tsa PVD li fana ka khanyetso e phahameng ea mocheso le ho roala, ho fokotsa likhohlano ka katleho, ho lelefatsa nako ea bophelo, le ho ntlafatsa ts'ebetso ea koloi ka kakaretso.
4. Kenyelletso ea Zhenhua FMA0605 PVD Hard Coating Equipment
Thepa Melemo
Filtration e sebetsang hantle ea li-arc macro-particles; Liaparo tsa Ta-C li fana ka ts'ebetso e phahameng le ts'ebetso e phahameng.
E fihlella ho thatafala ho hoholo, lirafshoa tse hanyetsanang le mocheso o phahameng haholo, coefficient e tlase ea khohlano, le ho hanyetsa ho hotle ha kutu. Karolelano ea boima bo fihla ho 25GPa–63GPa.
Cathode e sebelisa theknoloji ea li-drive tse peli e kopanyang khoele e eme ka pele le stacking ea makenete e sa feleng, e sebetsang hammoho le sistimi ea ion etching le sebopeho sa mahlakore a mangata a mahlakore a mararo ho fihlela deposition e sebetsang hantle.
E na le sebaka se seholo sa cathodic arc, se tiisang thepa e ntle ea ho pholile tlas'a maemo a phahameng a hona joale. Lebelo la ho sisinyeha ha arc spot le potlakile, sekhahla sa ionization se holimo, 'me sekhahla sa deposition se potlakile. Sena se etsa hore ho behoe liphahlo tse teteaneng le tse boreleli tse nang le khanyetso e phahameng ea oxidation le ts'ebetso e phahameng ea mocheso.
Sebaka sa Kopo:
Thepa e ka kenya AlTiN, AlCrN, TiCrAlN, TiAlSiN, CrN, le liphahlo tse ling tse sa keneleng mocheso o phahameng haholo, tse sebelisitsoeng haholo ka hlobo, lisebelisoa tsa ho itšeha, litebele, likarolo tsa koloi, lipiston le lihlahisoa tse ling.
