Carbide e entsoeng ka samente, joalo ka "meno a indasteri", ke thepa ea bohlokoa bakeng sa lisebelisoa tsa sejoale-joale. Tšebeliso ea eona e ntse e ata haholo, 'me e tumme haholo libakeng tse ngata tse kang oli le khase, merafo ea mashala, taolo ea mokelikeli, mechine ea kaho, sefofane le tse ling. Joale, mokhoa oa ho sebelisa lisebelisoa tse fokolang ho ntlafatsa katleho? Sena se hloka ho ntlafatsa ts'ebetso ea carbide e entsoeng ka samente ho ntlafatsa bophelo ba ts'ebeletso le katleho ea mosebetsi.

1.Ntlafatsa boleng ba lisebelisoa tse tala.

A.Ntlafatsa bohloeki ba lisebelisoa tse tala

Ho lumeloa hore ho latela lintlha tse kang Na, Li, B, F, Al, P, K le lintlha tse ling tse nang le litaba tse ka tlase ho 200PPm li na le tšusumetso e fapaneng phokotsong, carbonization le sintering ea carbide e entsoeng ka samente ea N powder, phello ea thepa le sebopeho sa motsoako o boetse o lokela ho ithutoa.Ka mohlala, li-alloys tse nang le matla a phahameng le matla a phahameng a ts'usumetso (joaloka li-alloys tsa merafo le lisebelisoa tsa ho sila) li na le litlhoko tse phahameng, ha lisebelisoa tsa ho itšeha tse tsoelang pele tse nang le tšusumetso e tlaase empa li phahame. ho nepahala ha machining ha ho hloke bohloeki bo phahameng ba lintho tse bonahalang.

B.Laola boholo ba likaroloana le kabo ea lisebelisoa tse tala

Qoba likaroloana tse kholo ka har'a lisebelisoa tse tala tsa carbide kapa cobalt, 'me u thibele ho thehoa ha lijo-thollo tse mahoashe tsa carbide le matamo a cobalt ha motsoako o silafatsoa.

Ka nako e ts'oanang, boholo ba likaroloana le sebopeho sa boholo ba lisebelisoa tsa lihlahisoa tse tala li laoloa ho finyella litlhoko tsa lihlahisoa tse fapaneng. Mohlala, lisebelisoa tsa ho itšeha li lokela ho sebelisa phofo ea tungsten carbide e nang le boholo ba karolo ea Fisher e ka tlase ho li-micron tse 2, lisebelisoa tse sa sebetseng li lokela ho sebelisa 2-3 microns tungsten carbide phofo, 'me lisebelisoa tsa merafo li lokela ho sebelisa phofo ea tungsten carbide e kholo ho feta li-microns tse 3.

2. Ntlafatsa sebopeho sa microstructure ea alloy.

Ultrafine Grain Alloy

Boholo ba lijo-thollo tsa carbide bo ka tlase ho 1μm, 'me e ka ba le boima bo phahameng le boima ka nako e le' ngoe.

Li-Alloys tsa Mehaho tse fapaneng

Heterogeneous structure alloy ke mofuta o ikhethileng oa carbide e entsoeng ka samente e nang le microstructure e sa lekaneng kapa sebopeho, e entsoeng ka ho kopanya mefuta e 'meli ea metsoako e nang le likarolo tse fapaneng kapa boholo bo fapaneng ba likaroloana. Hangata e na le ho tiea ho hoholo ha li-alloys tse mahoashe le khanyetso e phahameng ea li-alloys tse entsoeng hantle, kapa bobeli bo matla bo phahameng ba li-alloys tse phahameng tsa cobalt le khanyetso e phahameng ea li-alloys tse tlase tsa cobalt.

Superstructural Alloys

Ka ts'ebetso e khethehileng ea tlhahiso, sebopeho sa alloy se entsoe ka libaka tsa anisotropic tungsten carbide single crystal flake tse kopantsoeng ke methapo ea tšepe e nang le cobalt. Alloy ena e na le khanyetso e ikhethang le e tšoarellang haholo ha e ts'oaroa khafetsa.

Alloy ea Gradient

Li-alloys tse nang le liphetoho tsa gradient sebopeho li lebisa ho liphetoho tse thata ho thata le ho tiea.

3. Ntlafatsa kapa u khethe karolo e ncha e thata le karolo ea tlamahano.

4. Phekolo e thatafatsang sefahleho.

Rarolla ho se lumellane pakeng tsa ho hanyetsa ho apara le ho tiea, ho thatafala le matla a carbide e entsoeng ka samente.

Ho roala:Deposit lera la TiC kapa TiN holim'a motsoako o thata ka ho tiea ho betere ka mekhoa ea 'mele kapa ea lik'hemik'hale ho eketsa khanyetso ea alloy.

Hajoale, nts'etsopele e potlakileng ka ho fetesisa ea boronizing, nitriding, le electro spark deposition ke carbide e koahetsoeng ka samente.

5. Ho eketsa likarolo kapa metsoako.

6. Phekolo ea mocheso oa carbide e entsoeng ka samente.
