Cr3C2-NiCr ee heerkulka-sare ee ka-hortagga oksaydhka iyo xidhashada caabbinta
Sharaxaada
Cr3C2-NiCr waa walxo isku dhafan oo aad waxtar u leh oo si ballaaran loogu isticmaalo warshadaha u baahan heerkul sare iyo xirashada caabbinta.Maaddadu waxay ka kooban tahay chromium carbide (Cr3C2) iyo nikkel-chromium (NiCr) alloy, taasoo ka dhigaysa xal ku habboon codsiyada halkaasoo oksaydhka heerkulka sare iyo xirashada caabbinta loo baahan yahay.
Darajooyinka KF-70, KF-69, iyo KF-71 ee Cr3C2-NiCr waxay caan ku yihiin waxqabadkooda sare iyo ku adkeysiga xaaladaha heerkulka sare.Cabbirka walxaha fasal kastaa wuxuu u dhexeeyaa 15-45 μm iyo 20-53 μm, waana la isku daray oo la miiray si loo hubiyo awoodda ugu badan.
KF-70 Cr3C2-25NiCr waxay bixisaa iska caabin heer sare ah oo oksaydhka iyo xidhashada at 815 ℃.Waxaa aad loogu talinayaa in lagu codsado jawi kuleyl sare leh oo u baahan waxqabad dheer, sida marawaxadaha iyo matoorada gaaska.
KF-69 Cr3C2-20NiCr waa darajo kale oo aad waxtar u leh oo bixisa iska caabin heersare ah oo oksaydheynta iyo xirashada 815 ℃.Waxay ku habboon tahay in loo isticmaalo codsiyo heerkul sare oo ballaaran, oo ay ku jiraan ka-hortagga kiimikada iyo daaweynta kulaylka.
KF-71 Cr3C2-30NiCr waa darajo wax qabad sare leh oo bixiya adkeysi ka wanaagsan kan darajooyinka kale ee qoyska Cr3C2-NiCr.Waxaa aad loogu talinayaa codsiyada halka adkeysiga iyo adkeysigu ay muhiim u yihiin, sida qalabka qodista saliidda iyo gaasta, caaryada heerkulka sare leh, iyo qalabka wax tuurista ee dhinta.
Marka la soo koobo, qoyska Cr3C2-NiCr ee alaabta, oo ay ku jiraan KF-70, KF-69, iyo KF-71, waa xal ku habboon codsiyada u baahan oksaydhka heerkulka sare iyo xirashada caabbinta.Alaabooyinkani waxay bixiyaan adkeysi sare iyo adkeysi heerkul sare ah, taasoo ka dhigaysa mid ku haboon in loo isticmaalo warshadaha sida hawada hawada, baabuurta, iyo tamarta.Wax qabadkooda iyo isku halaynta wanaagsan, alaabada Cr3C2-NiCr waa doorasho aad u fiican qof kasta oo raadinaya xal tayo sare leh, oo dheer oo loogu talagalay codsiyada heerkulka sare.
