Substrate e sebetsang
Tšepe ea carbon, tšepe e sa hloekang, tšepe e entsoeng ka tšepe, motsoako oa aluminium, alloy ea titanium, tšepe ea alloy ea mocheso o phahameng, litene tse sireletsang, likhoele tse sireletsang, likhalase, lirafshoa, li-castable tse nang le mocheso o phahameng kaofela li ka sebelisoa holim'a li-alloys tse ling.
Mocheso o sebetsang
Mocheso o phahameng oa ho hanyetsa ke 1400 ℃, 'me o hanyetsana le khoholeho e tobileng ka malakabe kapa ho phalla ha khase e phahameng ea mocheso.
Ho hanyetsa mocheso oa ho roala ho tla fapana ho ea ka ho hanyetsa mocheso oa li-substrates tse fapaneng. E hanana le serame le mocheso le ho thothomela ha mocheso.
Likarolo tsa sehlahisoa
1. Li-nano-coatings li na le karolo e le 'ngoe, li na le tikoloho, ha li na chefo, li bonolo ho li sebelisa ebile li na le ts'ebetso e tsitsitseng.
2. Ho roala ho teteaneng, ho khahlanong le oxidation, acid le alkali manganga, 'me ho hanyetsa mocheso o phahameng oa mocheso.
3. Li-nano-coatings li na le matla a matle a ho kenella. Ka ho kenella, ho roala, ho tlatsa, ho tiisa le ho etsa filimi, qetellong ba finyella tiiso e tsitsitseng ea likarolo tse tharo le anti-oxidation.
4. E na le ts'ebetso e ntle ea ho etsa filimi 'me e ka etsa lera le teteaneng la filimi.
5. Ho roala ho hanyetsana le mocheso o phahameng oa mocheso le mocheso oa mocheso, ho na le ho hanyetsa mocheso o motle oa mocheso, 'me ho fetile liteko tsa ho pholile ha metsi ka makhetlo a fetang 20 (ho hanyetsa mocheso le mocheso oa mocheso, ho roala ha ho phunye kapa ho senya).
6. Ho khomarela ha ho roala ho feta 5 MPa.
7. Mebala e meng kapa thepa e 'ngoe e ka fetoloa ho latela litlhoko tsa bareki.
Libaka tsa kopo
1. Sebaka sa tšepe, bokaholimo ba khalase, bokaholimo ba ceramic;
2. Ho tiisa bokaholimo ba graphite le anti-oxidation, ho tiisa holim'a mocheso o phahameng oa mocheso le ho thibela ho bola;
3. Mefuta ea graphite, likarolo tsa graphite;
4. Likarolo tsa boiler, lisebelisoa tsa mocheso, li-radiator;
5. Lisebelisoa tsa sebōpi sa motlakase le lisebelisoa tsa motlakase.
Mokhoa oa tšebeliso
1. Tokiso ea pente: Ka mor'a ho sisinyeha kapa ho sisinyeha hantle, e ka sebelisoa ka mor'a ho sefshoa ka skrine ea filtara ea 300-mesh. Ho hloekisa lisebelisoa tsa motheo: Kamora ho theola le ho tlosa mafura, ho khothaletsoa ho etsa sandblasting ho ntlafatsa phello ea bokaholimo. Phello e ntle ka ho fetisisa ea sandblasting e finyelloa ka 46-mesh corundum (white corundum), 'me e hlokeha ho fihla sehlopheng sa Sa2.5 kapa ka holimo. Lisebelisoa tsa ho roala: Sebelisa lisebelisoa tsa ho roala tse hloekileng le tse omeletseng ho netefatsa hore ha ho na metsi kapa litšila tse ling tse khomarelang ho tsona, e le hore li se ke tsa ama phello ea ho roala kapa esita le ho baka lihlahisoa tse nang le bokooa.
2. Mokhoa oa ho roala: Ho fafatsa: Fafatsa mocheso oa kamore. Ho khothalletsoa ho laola botenya ba ho fafatsa ka har'a 50 ho isa ho 100 microns. Pele o fafatsa, workpiece ka mor'a sandblasting e lokela ho hloekisoa ka anhydrous ethanol le ho omisoa ka moea o hatelitsoeng. Haeba ho fokotseha kapa ho honyela ho etsahala, mosebetsi o ka futhumatsoa pele ho hoo e ka bang 40 ℃ pele o fafatsa.
3. Lisebelisoa tsa ho roala: Sebelisa sethunya sa spray se nang le bophara ba 1.0. Sethunya sa spray se nang le bophara bo nyane se na le phello e ntle ea atomization le sephetho se nepahetseng haholoanyane sa ho fafatsa. Air compressor le sefe ea moea li hloka ho hlomelloa.
4. Pholiso ea ho roala: Ka mor'a hore ho fafatsa ho phethoe, tlohela workpiece ka tlhaho hore e omelle ka holim'a metsi ka metsotso e ka bang 30, ebe u e beha ka ontong 'me ue boloke ka likhato tse 280 ka metsotso e 30. Ka mor'a ho pholile, e ka ntšoa hore e sebelisoe.
E ikhethang ho Youcai
1. Botsitso ba tekheniki
Ka mor'a tlhahlobo e matla, ts'ebetso ea theknoloji ea aerospace-grade nanocomposite ceramic e ntse e tsitsitse tlas'a maemo a feteletseng, e hanyetsanang le mocheso o phahameng, mocheso oa mocheso le ho bola ha lik'hemik'hale.
2. Theknoloji ea ho hasana ha Nano
Mokhoa o ikhethang oa ho hasana o tiisa hore nanoparticles li arolelitsoe ka mokhoa o ts'oanang ka ho roala, ho qoba ho kopana. Kalafo e sebetsang hantle ea li-interface e ntlafatsa maqhama pakeng tsa likaroloana, ho ntlafatsa matla a tlamahano pakeng tsa ho roala le substrate hammoho le tshebetso ka kakaretso.
3. Coating controllability
Liqapi tse nepahetseng le mekhoa e kopanetsoeng li etsa hore ts'ebetso ea ho roala e khonehe, e kang ho thatafala, ho hanyetsa ho roala le botsitso ba mocheso, ho finyella litlhoko tsa likopo tse fapaneng.
4. Litšobotsi tsa sebopeho sa Micro-nano:
Likaroloana tsa ceramic tsa nanocomposite li phuthela likaroloana tsa micrometer, li tlatsa likheo, li etsa lesela le teteaneng, 'me li matlafatsa ho tiea le ho hanyetsa kutu. Ho sa le joalo, li-nanoparticles li kenella ka holim'a substrate, li etsa interphase ea tšepe-ceramic, e matlafatsang matla a ho kopanya le matla a kakaretso.
Molao-motheo oa lipatlisiso le nts'etsopele
1. Taba ea ho kopanya mocheso oa mocheso: Li-coefficients tsa ho atolosa mocheso oa lisebelisoa tsa tšepe le tsa ceramic hangata li fapana nakong ea ho futhumatsa le ho pholisa. Sena se ka lebisa ho thehoeng ha li-microcracks ka har'a koae nakong ea ts'ebetso ea libaesekele tsa mocheso, kapa esita le ho phunya. E le ho rarolla bothata bona, Youcai o thehile lisebelisoa tse ncha tsa ho roala tseo coefficient ea eona ea ho atolosa mocheso e leng haufi le ea substrate ea tšepe, kahoo e fokotsa khatello ea mocheso.
2. Ho hanyetsa mocheso oa mocheso le ho sisinyeha ha mocheso: Ha tšepe ea holim'a tšepe e fetoha ka potlako pakeng tsa mocheso o phahameng le o tlaase, e tlameha ho khona ho mamella khatello ea mocheso e hlahisoang ntle le tšenyo. Sena se hloka hore seaparo se be le khanyetso e ntle ea mocheso oa mocheso. Ka ho ntlafatsa microstructure ea ho roala, joalo ka ho eketsa palo ea li-interfaces le ho fokotsa boholo ba lijo-thollo, Youcai e ka ntlafatsa ho hanyetsa mocheso oa mocheso.
3. Matla a ho kopanya: Matla a ho kopanya pakeng tsa ho roala le karolo ea tšepe ea tšepe ke ea bohlokoa bakeng sa botsitso ba nako e telele le ho tšoarella ha seaparo. Ho matlafatsa matla a tlamahano, Youcai e hlahisa lera le lipakeng kapa lesela la phetoho lipakeng tsa ho roala le substrate ho ntlafatsa ho koloba le tlamahano ea lik'hemik'hale lipakeng tsa tse peli.
