Nzvimbo dzekushandisa dzeThermal Spray Technology

Mumakore achangopfuura, tekinoroji yekupfapfaidza yekupisa yakashanduka kubva kune isina kuchena maitiro ayo anga achinetsa kudzora, kuita akawedzera chaiwo maturusi uko maitiro akagadzirirwa kutarisisa zvimiro zvezvose zvakaiswa zvinhu uye machira anodiwa.

Tekinoroji yekupfapfaidza tekinoroji iri kuramba ichikura uye maapplication matsva anoonekwa ezvekupfapfaidza zvekupfapfaidza zvinhu uye zvimiro. Ngatidzidzei nzvimbo huru dzekushandisa tekinoroji yekupisa yekupisa.

1. Ndege

Thermal spraying tekinoroji inoshandiswa zvakanyanya mumunda wendege, sekupfapfaidza thermal barriers coatings (bonding layer + ceramic surface layer) pamashizha enjini yendege. Plasma spraying, supersonic flame spraying bonding layers, senge NiCoCrAlY neCoNiCrAlY, uye ceramic surface layer, se8% Y0-ZrO(YSZ) oxide (ine isingawanzo pasi oxide) doping YSZ kugadziridzwa, seTiO+YSZ, YSZ+ A10 kana zvisingawanzo pasi pasi lanthanum zirconate-based oxides akadai seLa(ZoCe)024 akaongororwawo semafuta ekuvharisa mabhairi pamakamuri ekupisa ejini reroketi5. Iyo huru rotor shaft yeherikoputa yekushanda kwemauto munzvimbo dzerenje inokukurwa nyore nyore nejecha. Iko kushandiswa kweHVOF uye kupfapfaidza kunoputika kweWC12Co kunogona kuvandudza kusakara kwayo. HVOF inopfapfaidza Al-SiC yekuputira pane magnesium alloy substrate yekubhururuka, iyo inogona kuvandudza kupfeka kuramba.

2. Steel uye Oiri Indasitiri

Indasitiri yesimbi nesimbi ibasa rakakosha rekupfapfaidza kwemafuta, uye ndiyo yechipiri indasitiri yakakura muChina mushure mekushandiswa kwemafuta ekupfapfaidza muindasitiri yezvendege. Muna 2009, China crude simbi yakabuda yakaita 47% yepasi rose crude simbi yakabuda. Inyika yesimbi chaiyo, asi haisi imba yesimbi. Dzimwe simbi dzemhando yepamusoro dzichiri kuda kutengwa kunze kwenyika dzakawanda. Chimwe chezvikonzero zvakakosha ndechekuti kupfapfaidza kweChina kunoshandiswa kushoma muindasitiri yesimbi. Zvakadai se blast furnace tuyere, high-temperature annealing furnace roller, hot roller plate conveying roller, support roller, straightening roller, galvanized kusimudza roller, siking roller, etc. Kushandiswa kwekupisa kwepfapfaidzo pazvikamu izvi kunogona kuvandudza zvakanyanya kushanda zvakanaka uye kuderedza mari, Kuvandudza kunaka kwezvigadzirwa, uye mabhenefiti akakosha 19-0.

Pamusangano weITSC wa2011, nyanzvi yekuJapan Namba yakaferefeta pamatendi ane chekuita nekushandiswa kwekupfapfaidza kupisa muindasitiri yesimbi pasi rose. Migumisiro yeongororo inoratidza kuti kubva muna 1990 kusvika muna 2009, maJapan patents aisvika 39%, US patents aiverengera 22%, European patents aiverengera 17%, Chinese patents aiverengera 9%, Korean patents account ye6%, Russian patent account ye3. %, Brazilian patents inoita 3%, uye Indian patents inotora 1%. Zvichienzaniswa nenyika dzakabudirira dzakadai seJapan, Europe, neUnited States, kushandiswa kwekupfapfaidza kwemafuta muindasitiri yesimbi kuChina kushoma, uye nzvimbo yebudiriro yakakura.

Mishumo yakadzama ine chekuita nemusangano uyu zvakare yaisanganisira NiCrAlY neYO hupfu sezvishandiso, NiCrAlY-Y0 pfapfaidzo yehupfu dzakagadzirwa neagglomeration sintering uye nzira dzekusanganisa, uye machira akagadzirwa neHVOFDJ2700 pfapfaidzo pfuti. Tevedzera anti-buildup yevira remoto muindasitiri yesimbi. Mhedzisiro yetsvagiridzo inoratidza kuti iyo poda yekuputira yakagadziriswa neiyo agglomeration sintering nzira ine yakanakisa anti-manganese oxide kuvaka-up kuramba, asi kushomeka kuramba kune iron oxide kuvaka-up. Zvipfeko zvakagadzirirwa kubva kuhupfu hwakasanganiswa.

Thermal spraying tekinoroji inoshandiswa zvakanyanya mugasi, pombi yemafuta, uye gedhi vharafu pamusoro pekupfapfaidza anti-corrosion uye kupfeka-resistant coatings, mazhinji acho ari HVOF kumwaya WC10Co4Cr coating.

3. Simba idzva, midziyo mitsva, uye turbines gasi

Solid mafuta maseru (SOFCs) ikozvino akagadzirwa akananga kune akafuratira mahwendefa uye mahwendefa matete, anosanganisira anodes, electrolytes, cathodes,uye zvidimbu zvekudzivirira. Parizvino, dhizaini yekugadzira uye tekinoroji yekugadzira yemafuta akasimba maseru akura, uye dambudziko guru ndiro dambudziko rekugadzirira. Thermal spraying technology (low-pressure plasma spraying, vacuum plasma spraying) ndiyo inonyanya kufarirwa teknolojia. Iko kushandiswa kwakabudirira kwekupfapfaidza kwekupisa paSOFC ndiko kushandiswa kwazvino kwetekinoroji yekupfapfaidza tekinoroji musimba idzva, uye zvakare inosimudzira kuvandudzwa kwezvinhu zvine chekuita nekupfapfaidza. Semuenzaniso, plasma yakapfapfaidza LaSrMnO (LSM) spray material, kambani yeGermany HC.Starck yakatotanga kugadzirwa uye kutengesa kwezvinhu izvi nezvimwe zvinhu zvine chokuita. Vatsvakurudzi vakashandisawo mvura-phase plasma spraying kugadzirira electrode material LiFePO ye lithium-ion mabhatiri. mishumo yetsvakurudzo yakabatana.

Iko kuvandudza tekinoroji yekupfapfaidza tekinoroji haina kupatsanurwa kubva pakuvandudzwa kwemidziyo. Musangano wega wega wepasi rose wekupfapfaidza kupisa uchave nemishumo pamusoro pemidziyo mitsva ine hukama. Nekuda kwekudzikira kwayo tembiricha uye dhizaini yekumhanyisa, pfuti yeK2 yekupfapfaidza yeGTV HVOF inogona kupfapfaidza masimbi esimbi akadai seCu coatings, uye oxygen yemukati yejasi ingori 0.04%, inofananidzwa nekupfapfaidza kunotonhora. Uchishandisa high-pressure HVOF spraying system, iyo yekupisa kamuri yekumanikidza inogona kusvika 1 ~ 3MPa, uye murazvo unoyerera wakadzika tembiricha uye kumhanya kwakanyanya, kupfapfaidza 316L Stainless simbi poda, iyo deposition inoshanda inogona kusvika 90%.

Industrial gasi turbine mablades atanga kushandisa plasma-sprayed thermal barrier coatings, seYSZ, LazZrzO, SmzZrzO, GdzZr20 coating system, ayo anoshandiswa zvakanyanya kunze kwenyika uye parizvino ari yakakurumbira nzvimbo yekutsvagisa kuChina.

4. Mechanical kupfeka kusagadzikana

Tekinoroji yekupfapfaidza tekinoroji yagara iri chikamu chakakosha chemusangano wega wega wepasi rose wekupfapfaidza wepasirese mundima yekupfeka kuramba nekuti dzinenge dzese nzvimbo dzebasa dzakasakara uye kubvaruka, uye kusimbaradza kwepamusoro nekugadzirisa ndiwo mafambiro emangwana ebudiriro yetekinoroji, kunyanya neTekinoroji. zvakasiyana-siyana zvekushandisa muindasitiri inodzivirira kupfeka uye inosimudzirawo kuvandudzwa kweiyo thermal spray kupfeka-resistant zvinhu. Iyo inonyanya kushandiswa kupfeka-inodzivirira coatings ndeiyi: spray welding (flame spraying + remelting) NiCrBSi alloys, ayo ariwo anonyanya kushandiswa uye akadzidzwa mumunda usingapfeki, senge HVOF spraying FeCrNBC coating, arc spraying NiCrBSi mushure mekudzokorora Tsvagiridzo. pane microstructure uye kupfeka kuramba, nezvimwewo; HVOF kupfapfaidza, kutonhora kupfapfaidza tungsten carbide-based coatings, uye chromium carbide-based coatings ndiyo inonyanya kushandiswa uye yakatsvakwa mumunda wekuramba kupfeka; Indasitiri yekuChina yepamusoro-soro tungsten carbide-based spray powders inotsamira pane zvinotengwa kunze kwenyika, zvakaita sendege Kupfapfaidza furemu inodonha, roller inonyura, corrugating roller, etc. Nekugadzirwa kwekupfapfaidza kunotonhora uye tekinoroji yekupfapfaidza inodziya kugadzirira tungsten carbide-based coating, kune zvakare zvinodiwa zvitsva zve tungsten carbide-based spraying powder, senge poda particle size inodiwa ndeye -20um+5um.

5. Nanostructures uye zvinhu zvitsva

Nanostructured coatings, poda, uye zvinhu zvitsva zvanga zviri zvinotariswa kutsvagurudzo yepasirese mumakore apfuura. Nanostructured WC12Co coating inogadzirwa neHVOF spraying. Hukuru hwehupfu hwehupfu hwakapfapfaidzwa -10μm+2μm, uye saizi yezviyo zveWC i400nm. Kambani yeGerman DURUM ine maindasitiri ekugadzira. Me lenvk akadzidza WC10Co4Cr poda yakagadzirwa nekushandisa tungsten carbide ine saizi yezviyo zvakasiyana semidziyo yakabikwa, senge WC saizi yezviyo> 12um (yakajairika chimiro), WC saizi yezviyo 0.2 ~ 0.4um (yakanaka zviyo chimiro), WC saizi yezviyo ~0.2um (ultra-fine zviyo chimiro); WC saizi yezviyo

12um (yakajairika chimiro), WC saizi yezviyo 0.2 ~ 0.4um (yakanaka zviyo chimiro), WC saizi yezviyo ~0.2um (ultra-fine zviyo chimiro); WC saizi yezviyo

6. Biomedical uye kudhinda mapepa

Thermal spray tekinoroji inowedzera uye zvakanyanya kushandiswa muindasitiri yekurapa, senge vacuum plasma, HVOF yakapfapfaidza Ti, hydroxyapatite, uye hydroxyapatite + Ti machira anoshandiswa muindasitiri yekurapa (mazino, orthopedics). Kuputika kwekupfapfaidza kweTiO2-Ag, senge deposition paCu coils yemaair conditioners, inogona kutadzisa kukura kwebhakitiriya uye kuvachengeta vakachena.
