Ruitai Kitchen Knives: Tonakholo Mohloli oa hau oa Lithipa tse Tloaelehileng tsa Kitchen tse tsoang China
Ho na le mefuta e 'meli ea mekhoa e tloaelehileng ea ho roala lithulusi: ho beha mouoane oa lik'hemik'hale (cvd) le ho beha mouoane oa 'mele (pvd) hajoale. Lilemong tsa morao tjena, mekhoa e meng e mecha ea ho roala e hlahile, e nang le tebello e ntle ea kopo.
CVD
Mokhoa oa CVD, oo e leng oa deposition ea athomo, ke mokhoa oa ho etsa lera le tiileng la deposition holim'a matrix a futhumatsang ka ho sebelisa mouoane, hydrogen le likarolo tse ling tsa lik'hemik'hale tsa tšepe halide mocheso o phahameng oa 950 ~ 1050 ℃. Ts'ebetso ena e kenyelletsa mekhahlelo e meraro: vaporization ea lintho tse bonahalang, lipalangoang ho ea sebakeng sa matrix le ho thehoa ha lesela holim'a matrix.
Har'a mefuta eohle ea mekhoa ea cvd, vacuum ion bombardment le magnetron ion reaction spraying ke tsona tse sebelisoang haholo. Theknoloji ea cvd e sebelisoa haholo-holo bakeng sa ho roala holim'a lisebelisoa tsa ho itšeha tsa carbide, tse loketseng ho potlaka ka lebelo le phahameng le ho qeta ho itšeha ha mahareng le ho boima.
Ha ho bapisoa le mekhoa e meng ea ho roala, mokhoa oa cvd ha o na melemo feela ea lisebelisoa tse bonolo, ts'ebetso e butsoitseng, empa hape o na le melemo e latelang:
Ho na le mefuta e mengata ea sediments, e ka tlotsoang ka tšepe, alloys, carbides, nitrides, borides, oxides, carbon nitrides, oxygen nitrides, hydro-carbon nitrides, joalo-joalo: Ka mokhoa o phahameng oa ho phunyeletsa le ho ts'oana, liphahlo tse ngata tse nang le lisele tse fapaneng li ka fumanoa, 'me botenya ba ho roala bo lekana. Sekhahla sa deposition se holimo ebile se bonolo ho se laola. Ho roala ho na le bohloeki bo phahameng le lijo-thollo tse ntle le tse teteaneng. Ho khomarela ka matla ho ka fumana ho roala ho teteaneng. Theko e tlase ea ts'ebetso, e loketseng tlhahiso ea bongata.
PVD
Mokhoa oa PVD ke ho tlosa lisebelisoa ho tsoa mehloling e shebiloeng ka mefuta ea 'mele e kang mouoane kapa ho fafatsa, ebe o kenya li-ion tsa mouoane tse matla holim'a substrate kapa karolo e ka holimo ho etsa lera la filimi ka har'a vacuum kapa semi-vacuum sebaka. The mouoane karabelo ea evaporated kapa sputtered tšepe liathomo lebisa ho deposition ea metsoako e hlokehang holim'a sesebelisoa. Pvd e ka koaheloa ka titanium nitride, titanium carbon nitride, aluminium titanium nitrogen compounds, hammoho le lirafshoa tse fapaneng tsa li-carbides le nitride.
Theknoloji ea PVD e sebelisoa haholo kalafong ea holim'a lisebelisoa tsa carbide tse kentsoeng ka thata le lisebelisoa tsa tšepe tsa lebelo le phahameng. E sebelisitsoe haholo kalafong ea ho roala ea sekontiri se entsoeng ka carbide, sehahi sa milling, reamer, pompo, sesebelisoa se nang le sebopeho se ikhethileng, sesebelisoa sa welding joalo-joalo.
MT-CVD
The tcn barbotage e nang le letenya fibrous crystalline morpholoji ka fumanoa ka mocheso o mahareng lik'hemik'hale mouoane deposition (MT-CVD) ka 700 ~ 900 ℃. Botenya ba ho roala bo ka fihla ho 8 ~ 10μm, 'me e ka ba a2o3, tin ka holim'a lera ka theknoloji ea cvd.
Lehare la ho roala la MT-CVD le loketse lebelo le phahameng, mocheso o phahameng, mojaro o moholo, maemo a omileng a ho itšeha, bophelo ba eona bo ka ba habeli ho feta ba lehare le tloaelehileng la ho roala. cvd drawback e ka sehloohong ea mokhoa ona ke hore mocheso oa deposition o phahame, 'me sesebelisoa sa annealing le deformation se tla etsahala ha sesebelisoa sa tšepe sa lebelo le phahameng se koahetsoe. Ka hona, sesebelisoa se kentsoeng se tlameha ho tlosoa.
