Cr3C2-NiCr mo le maualuga o le vevela anti-oxidation ma le ofuina o le teteʻe
Fa'amatalaga
Cr3C2-NiCr o se mea tu'ufa'atasi sili ona lelei e fa'aaogaina lautele i alamanuia e mana'omia ai le maualuga o le vevela ma le fa'aogaina o le ofuina.O meafaitino e aofia ai le chromium carbide (Cr3C2) ma le nickel-chromium (NiCr) alloy, ma avea ai ma se fofo lelei mo talosaga e manaʻomia ai le faʻamaʻiina o le vevela ma le faʻafefeteina.
O le KF-70, KF-69, ma le KF-71 togi o le Cr3C2-NiCr ua lauiloa mo a latou faatinoga maualuga ma le tumau i lalo o tulaga maualuga-vevela.Ole lapopo'a o vasega ta'itasi e mai le 15-45 μm ma le 20-53 μm, ma o lo'o fa'apipi'iina ma fa'amauina e fa'amautinoa ai le malosi maualuga.
KF-70 Cr3C2-25NiCr e ofoina atu le teteʻe lelei i le faʻamaʻiina ma ofuina i le 815 ℃.E sili ona fautuaina mo faʻaoga i siosiomaga maualuga-vevela e manaʻomia ai le faʻatinoga umi, e pei ole turbine blades ma gas turbine engines.
KF-69 Cr3C2-20NiCr o se isi vasega sili ona aoga e ofoina atu le teteʻe sili atu i le faʻamaʻiina ma le ofuina i le 815 ℃.E fetaui lelei mo le faʻaaogaina i le tele o faʻaoga maualuga-vevela, e aofia ai le gaosiga o vailaʻau ma le vevela.
KF-71 Cr3C2-30NiCr o se togi pito i luga e ofoina atu le malosi sili atu nai lo isi togi i le aiga Cr3C2-NiCr.E matua fautuaina lava mo talosaga e taua tele le tumau ma le malosi, e pei o mea faigaluega suau'u ma kesi viliina, suauʻu maualuga-vevela, ma mea faʻapipiʻi oti.
I le aotelega, o le Cr3C2-NiCr aiga o oloa, e aofia ai KF-70, KF-69, ma KF-71, o se fofo lelei mo talosaga e manaʻomia ai le faʻamaʻiina o le vevela maualuga ma le faʻaogaina o le faʻaogaina.O nei oloa e ofoina atu le sili atu le tumau ma le malosi i lalo o tulaga maualuga-vevela, ma faʻaogaina lelei mo le faʻaaogaina i alamanuia e pei o le vaalele, taʻavale, ma le malosi.Faatasi ai ma a latou faʻatinoga sili ona lelei ma faʻatuatuaina, o oloa Cr3C2-NiCr o se filifiliga sili ona lelei mo soʻo se tasi o loʻo sailia se fofo maualuga, umi umi mo talosaga maualuga-vevela.
