Libaka tsa Kopo tsa Theknoloji ea Thermal Spray

Lilemong tsa morao tjena, mahlale a ho fafatsa ka mocheso o fetohile ho tloha lits'ebetsong tse sa hloekang tseo ho neng ho le thata ho li laola, ho ba lisebelisoa tse nepahetseng haholoanyane moo mokhoa ona o etselitsoeng ho ela hloko thepa ea thepa e behiloeng le liphahlo tse hlokahalang.

Theknoloji ea ho fafatsa ka mocheso e ntse e tsoela pele ho nts'etsapele 'me lisebelisoa tse ncha li bonoa bakeng sa lisebelisoa le meaho ea ho roala ka mocheso. A re ithuteng libaka tse ka sehloohong tsa ts'ebeliso ea theknoloji ea spray ea mocheso.

1. Lifofane

Theknoloji ea ho fafatsa ka mocheso e sebelisoa haholo lefapheng la lifofane, joalo ka ho fafatsa liphahlo tse thibelang mocheso (bonding layer + ceramic surface layer) holim'a mahare a enjene ea sefofane. Plasma fafatsa, supersonic lelakabe fafatsa bonding layers, joalo ka NiCoCrAlY le CoNiCrAlY, le ceramic surface layer, joalo ka 8% Y0-ZrO(YSZ) oxide (e nang le rare earth oxide) doping YSZ modification, joalo ka TiO+YSZ, YSZ+ A10 kapa Li-oxide tsa lefatše tse sa tloaelehang tsa lanthanum zirconate tse kang La(ZoCe)024 li boetse li ithutoa e le liphahlo tse thibelang mocheso ka likamoreng tse tukang tsa rokete5. The rotor shaft e kholo ea li-helicopter bakeng sa ts'ebetso ea sesole libakeng tsa lehoatata e senyeha habonolo ke lehlabathe. Tšebeliso ea HVOF le ho fafatsa ka ho phatloha ha WC12Co ho ka ntlafatsa ho hanyetsa ha eona. HVOF e fafatsa Al-SiC coat holim'a magnesium alloy substrate bakeng sa sefofane, e ka ntlafatsang ho hanyetsa ho apara.

2. Indasteri ea tšepe le oli

Indasteri ea tšepe le tšepe ke sebaka sa bohlokoa sa ts'ebeliso ea sefafatsi sa mocheso, 'me ke indasteri ea bobeli e kholo ka ho fetisisa Chaena ka mor'a ts'ebetso ea ho fafatsa mocheso indastering ea lifofane. Ka 2009, tlhahiso ea tšepe e tala ea China e bile karolo ea 47% ea tlhahiso ea tšepe e tala lefatšeng. Ke naha ea 'nete ea tšepe, empa ha se ntlo ea motlakase ea tšepe. Litšepe tse ling tsa boleng bo holimo li ntse li hloka ho romelloa ka bongata linaheng tse ling. E 'ngoe ea mabaka a bohlokoa haholo ke hore ho fafatsa mocheso oa Chaena ha ho sebelisoe hakaalo indastering ea tšepe. Tse kang blast furnace tuyere, high-themperature annealing furnace roller, hot roller plate conveying roller, support roller, straightening roller, galvanized lifting roller, sink roller, joalo-joalo Tšebeliso ea ho roala ha mocheso oa mocheso likarolong tsena ho ka ntlafatsa haholo ts'ebetso ea mosebetsi le ho ntlafatsa haholo. fokotsa litšenyehelo, Ntlafatsa boleng ba lihlahisoa, 'me melemo e bohlokoa 19-0.

Sebokeng sa ITSC sa 2011, setsebi sa Japane Namba se ile sa batlisisa litokelo tsa molao tse amanang le tšebeliso ea ho fafatsa ka mocheso indastering ea tšepe lefatšeng ka bophara. Liphello tsa lipatlisiso li bontša hore ho tloha ka 1990 ho ea ho 2009, litokelo tsa litokelo tsa Majapane li ne li le 39%, litokelo tsa US li ne li le 22%, litokelo tsa Europe li ne li le 17%, litokelo tsa Machaena li ne li le 9%, litokelo tsa litokelo tsa Korea ke 6%, tsa Russia tsa 3. %, litokelo tsa patent tsa Brazil li etsa 3%, 'me litokelo tsa Maindia li etsa 1%. Ha ho bapisoa le linaha tse tsoetseng pele tse kang Japane, Europe le United States, tšebeliso ea ho fafatsa ka mocheso indastering ea tšepe Chaena e fokotsehile, ’me sebaka sa tsoelo-pele se seholo.

Litlaleho tse qaqileng tse amanang le seboka li ne li boetse li kenyelletsa li-powders tsa NiCrAlY le YO e le lisebelisoa tse tala, li-powders tsa NiCrAlY-Y0 li ne li lokisitsoe ka mekhoa ea ho sintering le ea ho kopanya, 'me liphahlo li ne li lokisitsoe ke sethunya sa spray sa HVOFDJ2700. Etsisa anti-buildup ea meqolo ea sebōpi indastering ea tšepe. Liphetho tsa lipatlisiso li bonts'a hore phofshoana e entsoeng ka phofo e lokiselitsoeng ke mokhoa oa agglomeration sintering e na le khanyetso e ntle ea anti-manganese oxide build-up, empa e fokola ho hanyetsa tšepe ea oxide. Liaparo tse lokiselitsoeng ho tloha ho phofo e tsoakiloeng.

Theknoloji ea ho fafatsa ka mocheso e sebelisoa haholo khase, liphaephe tsa oli, le li-valve tsa heke tse fafatsang li-anti-corrosion le liphahlo tse sa senyeheng, tseo boholo ba tsona e leng liphaephe tsa HVOF tse fafatsang WC10Co4Cr.

3. Matla a macha, lisebelisoa tse ncha, le li-turbine tsa khase

Lisele tse matla tsa mafura (SOFCs) joale li entsoe ka lehlakoreng la lipoleiti tse bataletseng le lipoleiti tse tšesaane, ho kenyeletsoa anode, electrolyte, cathodes,le lihlopha tse sireletsang. Hona joale, moralo oa thepa le theknoloji ea tlhahiso ea lisele tse tiileng tsa mafura li se li hōlile, 'me bothata bo ka sehloohong ke bothata ba ho lokisetsa. Theknoloji ea ho fafatsa ka mocheso (ho fafatsa ka plasma ka khatello e tlase, ho fafatsa ka plasma ea vacuum) e fetohile theknoloji e tsebahalang haholo. Tšebeliso e atlehileng ea ho fafatsa ka mocheso ho SOFC ke ts'ebeliso ea morao-rao ea theknoloji ea ho fafatsa ka mocheso ka matla a macha, hape e khothalletsa nts'etsopele ea lisebelisoa tse amanang le ho fafatsa. Ka mohlala, plasma e fafalitsoeng ka thepa ea spray ea LaSrMnO (LSM), k'hamphani ea Jeremane HC.Starck e se e qalile tlhahiso le thekiso ea thepa ena le thepa e amanang le eona. Bafuputsi ba ile ba boela ba sebelisa ho fafatsa plasma ea metsi ho lokisa lisebelisoa tsa electrode LiFePO bakeng sa libeteri tsa lithium-ion. litlaleho tsa lipatlisiso tse amanang.

Nts'etsopele ea theknoloji ea ho fafatsa ka mocheso e ke ke ea arohanngoa le ntlafatso ea lisebelisoa. Seboka se seng le se seng sa machaba sa ho fafatsa ka mocheso se tla ba le litlaleho mabapi le lisebelisoa tse ncha tse amanang. Ka lebaka la mocheso oa eona o tlase le moralo oa lebelo le phahameng, sethunya sa K2 sa spray sa GTV HVOF se ka fafatsa liphahlo tsa tšepe tse kang Cu coatings, 'me boemo ba oksijene ba seaparo ke 0.04% feela, e ka bapisoang le ho fafatsa ka serame. U sebelisa sesebelisoa sa ho fafatsa se nang le khatello e phahameng ea HVOF, khatello ea kamore e tukang e ka fihla ho 1 ~ 3MPa, 'me phallo ea lelakabe ke mocheso o tlase le lebelo le phahameng, ho fafatsa phofo ea tšepe e sa hloekang ea 316L, katleho ea deposition e ka fihla 90%.

Li-blade tsa turbine tsa indasteri li se li qalile ho sebelisa liphaephe tse thibelang mocheso oa plasma-sprayed, joalo ka YSZ, LazZrzO, SmzZrzO, GdzZr20 litsamaiso tsa ho roala, tse sebelisoang haholo kantle ho naha mme hajoale e le sebaka sa lipatlisiso se tsebahalang China.

4. Ho hanyetsa ho apara ka mechine

Theknoloji ea ho fafatsa ka mocheso e 'nile ea e-ba karolo ea bohlokoa ea kopano e' ngoe le e 'ngoe ea machaba ea ho fafatsa mocheso tšimong ea ho hanyetsa ho roala hobane hoo e batlang e le libaka tsohle tsa lisebelisoa li na le ho senyeha,' me ho matlafatsa le ho lokisoa ke mekhoa ea nakong e tlang ea tsoelo-pele ea theknoloji, haholo-holo ka Theknoloji e na le mefuta e mengata ea likopo indastering e manganga le e boetse e khothalletsa nts'etsopele ea lisebelisoa tse sa keneleng mocheso oa spray. Liaparo tse sebelisoang ka ho fetisisa tse sa senyeheng ke: ho cheselletsa ho fafatsa (ho fafatsa lelakabe + ho fafatsa) li-alloys tsa NiCrBSi, tseo hape li sebelisoang ka ho fetisisa le ho ithutoa tšimong e sa sebetseng, joalo ka HVOF fafatsa FeCrNBC coating, arc spraying NiCrBSi ka mor'a hore remelting Research ka microstructure le wear resistance, joalo-joalo; Ho fafatsa ka HVOF, ho fafatsa ka metsi a batang a tungsten carbide-based coatings, le liphahlo tse thehiloeng ho chromium carbide ke tsona tse sebelisoang ka ho fetisisa le tse entsoeng lipatlisiso lefapheng la ho hanyetsa ho apara; Indasteri ea maemo a holimo ea China ea tungsten carbide-based spray powders e itšetlehile ka thepa e tsoang linaheng tse ling, joalo ka lifofane Ho fafatsa foreimi e oelang, rolara e tebang, rolara e nang le makotikoti, joalo-joalo. ho boetse ho na le litlhoko tse ncha tsa ho fafatsa phofo e thehiloeng ho tungsten carbide, joalo ka tlhokahalo ea boholo ba karoloana ea phofo ke -20um+5um.

5. Nanostructures le lisebelisoa tse ncha

Liaparo tse entsoeng ka mokhoa o hlophisitsoeng, li-powders le lisebelisoa tse ncha e 'nile ea e-ba sepheo sa lipatlisiso tsa machaba ho theosa le lilemo. Nanostructured WC12Co coating e lokiselitsoe ke HVOF fafatsa. Boholo ba karoloana ea phofo e fafalitsoeng ke -10μm + 2μm, le boholo ba lijo-thollo tsa WC ke 400nm. Khampani ea Jeremane DURUM e na le tlhahiso ea indasteri. Me lenvk o ithutile phofo ea WC10Co4Cr e lokiselitsoeng ka ho sebelisa tungsten carbide e nang le boholo bo fapaneng ba lijo-thollo joalo ka lisebelisoa tse tala, joalo ka boholo ba lijo-thollo tsa WC> 12um (sebopeho se tloaelehileng), boholo ba lijo-thollo tsa WC 0.2 ~ 0.4um (sebopeho se setle sa lijo-thollo), boholo ba lijo-thollo tsa WC ~ 0.2um (sebopeho sa lijo-thollo tse ntle haholo); WC boholo ba lijo-thollo
