Okuqukethwe kwe-Cr kanye ne-C kuthinta kanjani ukumelana nokuguguleka kwamapuleti angagugi?
Ikhabhoni iyisici esiyinhloko sokwenza ama-carbide. Uma kukhona i-Cr, ikhabhoni ihlangana ne-chromium ukuze yakhe ama-carbide e-chromium (Cr₇C₃, Cr₃C₂, njll.). Uma okuqukethwe kwekhabhoni kuphakeme, kulapho okuqukethwe kwe-carbide kucebile khona, ngaleyo ndlela kuthuthukiswe ubulukhuni bento kanye nokumelana nokuguguleka kwayo.
I-Chromium iyisici esibalulekile ekwakhekeni kwama-carbide aqinile azinzile, futhi inokuqina okuhle kokushisa okuphezulu kanye nokumelana nokushiswa kwe-oxidation. Ohlelweni lwe-Cr ephezulu, amakristalu e-chromium carbide akhula abe yikholomu futhi ahlelwe ngendlela eqondile eqondene nokuguguleka, okusiza ukumelana nokuklwebheka kanye nokuguguleka komthelela. Ngaphezu kwalokho, i-Cr ingadlala indima ekucwengisisweni kokusanhlamvu ku-weld futhi ithuthukise ubuningi benhlangano.
Ekuklanyweni, okuqukethwe kwe-Cr kuvame ukulawulwa ku-18% ~ 30%, kanti okuqukethwe kwe-C kuphakathi kuka-3% ~ 5%. Lesi silinganiso singakha inani elikhulu lama-carbide ohlobo lwe-Cr₇C₃ asatshalaliswa ngokulinganayo anobulukhuni obuphezulu kanye ne-coefficient ephansi yokungqubuzana, okuthuthukisa ngempumelelo impilo yenkonzo yento ngaphansi kwezimo zokucindezela okuphezulu kanye nomthelela omkhulu.
