I-Cr3C2-NiCr ye-anti-oxidation ephezulu yobushushu kunye nokumelana nokunxiba
Inkcazo
I-Cr3C2-NiCr yinto esebenza kakhulu edibeneyo esetyenziswa ngokubanzi kumashishini afuna ukushisa okuphezulu kunye nokumelana nokunxiba.Izinto eziphathekayo zenziwe nge-chromium carbide (Cr3C2) kunye ne-nickel-chromium (i-NiCr) i-alloy, eyenza isisombululo esifanelekileyo kwizicelo apho i-oxidation ephezulu yokushisa kunye nokuxhatshazwa kokugqoka kuyadingeka.
I-KF-70, i-KF-69, kunye ne-KF-71 amabakala e-Cr3C2-NiCr ayaziwa ngokusebenza kwawo okuphezulu kunye nokuqina phantsi kweemeko eziphezulu zokushisa.Ubungakanani bamasuntswana ebakala ngalinye buvela kwi-15-45 μm kunye ne-20-53 μm, kwaye zihlanganisiwe kwaye zifakwe kwi-sintered ukuqinisekisa amandla aphezulu.
I-KF-70 Cr3C2-25NiCr inika ukuchasana okugqwesileyo kwi-oxidation kunye nokunxiba kwi-815 ℃.Kunconywa kakhulu kwizicelo kwiindawo ezinobushushu obuphezulu obufuna ukusebenza kwexesha elide, njengamaqabunga e-injini yomoya kunye neenjini ze-injini yegesi.
I-KF-69 Cr3C2-20NiCr lelinye ibakala elisebenza kakhulu elinika ukuxhathisa okuphezulu kwi-oxidation kunye nokunxiba kwi-815 ℃.Kukulungele ukusetyenziswa kuluhlu olubanzi lwezicelo eziphezulu zokushisa, kubandakanywa ukucutshungulwa kweekhemikhali kunye nokunyanga ukushisa.
I-KF-71 Cr3C2-30NiCr libakala eliqhuba kakuhle kakhulu nelinika ukuqina okungcono kunamanye amabanga kusapho lwe-Cr3C2-NiCr.Kucetyiswa kakhulu kwizicelo apho ukuqina kunye nokuqina kubalulekile, njengezixhobo zokomba ioyile kunye negesi, ukubumba okunobushushu obuphezulu, kunye nezixhobo zokulahla.
Isishwankathelo, intsapho ye-Cr3C2-NiCr yeemveliso, kuquka i-KF-70, i-KF-69, kunye ne-KF-71, isisombululo esifanelekileyo kwizicelo ezifuna i-oxidation ephezulu yokushisa kunye nokuxhatshazwa kokugqoka.Ezi mveliso zibonelela ngokuqina okuphezulu kunye nokuqina phantsi kweemeko zobushushu obuphezulu, zizenza zilungele ukusetyenziswa kumashishini afana ne-aerospace, izithuthi, kunye namandla.Ngokusebenza kwazo okugqwesileyo kunye nokuthembeka, iimveliso ze-Cr3C2-NiCr lukhetho oluhle kakhulu kuye nabani na ojonga umgangatho ophezulu, isisombululo esihlala ixesha elide kwizicelo zobushushu obuphezulu.
