Ruitai Kitchen Knives: Lau Puna'oa Muamua mo Custom Kitchen Knives Set mai Saina
E lua ituaiga o auala masani e fa'apipi'i ai meafaigaluega: fa'ama'i ausa (cvd) ma ausa fa'aletino (pvd) i le taimi nei. I tausaga talu ai nei, o nisi faiga faʻapipiʻi fou ua faʻaalia, o loʻo i ai se faʻamoemoega lelei.
CVD
O le auala CVD, lea e fa'atatau i le atomic deposition, o se metotia e fausia ai se fa'aputuga fa'amaumau i luga o le fa'avevela matrix e ala i le fa'aogaina o le ausa, hydrogen ma isi vaila'au o le halide u'amea i le maualuga o le vevela o le 950 ~ 1050 ℃. O le faagasologa e aofia ai vaega e tolu: vaporization o meafaitino, felauaiga i tafatafa o le matrix ma le fausia o le overlay i luga o le matrix.
I totonu o ituaiga uma o auala cvd, vacuum ion bombardment ma magnetron ion reaction spraying e sili ona faʻaaogaina. cvd tekinolosi e masani ona faʻaaogaina mo le faʻapipiʻiina o mea faʻapipiʻi sima carbide, lea e talafeagai mo le saoasaoa maualuga ma le faʻamaeʻaina o le tipi ma le mamafa.
Pe a faʻatusatusa i isi metotia faʻapipiʻi, cvd auala e le gata o loʻo i ai le lelei o meafaigaluega faigofie, faʻagasologa matua, ae o loʻo i ai foi tulaga lelei:
E tele ituaiga o palapala, e mafai ona ufiufi i metals, alloys, carbide, nitride, borides, oxides, carbon nitride, oxygen nitrides, hydro-carbon nitride, ma isi: Faʻatasi ai ma le maualuga o le faʻaogaina ma le tutusa, e mafai ona maua ni paʻu multilayer faʻatasi ai ma masini eseese, ma o le mafiafia o le ufiufi e tutusa. Ole fua ole fa'aputu e maualuga ma faigofie ona pulea. O le ufiufi e maualuga le mama ma fatu lelei ma mafiafia. O le pipii malosi e mafai ona maua ai se paluga mafiafia. Tau fa'agasologa maualalo, talafeagai mo le tele o gaosiga.
PVD
O le auala PVD o le aveese lea o mea mai puna faʻatatau e ala i foliga faʻapitoa e pei o le faʻasalaina poʻo le faʻafefe, ona faʻapipiʻi lea o nei ausa malosi i luga o le substrate poʻo se vaega o luga e fausia ai se ata tifaga e ala ile vacuum poʻo le vacuum space. O le tali ausa o uamea uamea ua mou atu po'o ua mapuna a'e e ta'ita'i atu ai i le fa'aputuina o mea e mana'omia i luga o le mea faigaluega. e mafai ona ufiufi le pvd i le titanium nitride, titanium carbon nitride, alumini titanium nitrogen compounds, faʻapea foʻi ma metals refractory eseese o carbide ma nitrides.
PVD tekinolosi e masani ona faʻaaogaina i luga o togafitiga o mea faʻapipiʻi sima carbide meafaigaluega ma meafaigaluega uʻamea maualuga saoasaoa. Ua faʻaaogaina lautele i le faʻapipiʻiina o togafitiga o sima carbide bit, milling cutter, reamer, tap, meafaigaluega faʻapitoa, faʻapipiʻi meafaigaluega ma isi.
MT-CVD
O le tcn coating ma mafiafia fibrous crystalline morphology e mafai ona maua e ala i le vevela vevela vapor deposition (MT-CVD) i le 700 ~ 900 ℃. O le mafiafia o le ufiufi e mafai ona oʻo atu i le 8 ~ 10μm, ma e mafai ona avea ma a2o3, apa i luga ole laiga e ala ile cvd technology.
MT-CVD coating lau e talafeagai mo le saoasaoa maualuga, vevela maualuga, uta tele, tulaga tipi mago, o lona olaga e tusa ma le faaluaina le maualuga nai lo le laʻau ufiufi masani. cvd drawback autu o le auala e faapea o le vevela vevela e maualuga, ma o le annealing meafaigaluega ma deformation o le a tupu pe a faʻapipiʻiina le meafaigaluega uamea meafaigaluega saoasaoa maualuga. O lea e tatau ona tineia le meafaigaluega na teuina.
