Ukuxhathisa kokunxiba okuphezulu kwentsimbi ye-carburized kungenxa yomxholo ophezulu wekhabhoni yomaleko womphezulu. Xa i-carbon yentsimbi w (C) ingaphantsi kwe-0.43%, inxenye e-carburized inethuba lokuxhathisa ukunxiba, kwaye xa w (C) Xa ingaphezulu kwe-0.45%, ukumelana nokunxiba kwezinto ezomeleleyo ezenziweyo kuyaphuculwa. Esi sisigqibo sokuba i-TH HACAHOBA itsale ngokusekwe kuvavanyo lwentsimi lwephini yomkhondo. Ke ngoko, isikhonkwane setrekta sithatha indawo yenkqubo entsha yokuqinisa ukuqina kwentsimbi engama-50. . Ukuthelekiswa kokuxhathisa kokunxiba kwe-w (C) ezahlukileyo emva kokucinywa kwe-induction kubonisa ifuthe lobume bentsimbi. Idatha etafileni ibonisa ukuba i-T7 yentsimbi ineyona mali incinci yokunxiba, kwaye umxholo wayo wekhabhoni kunye nokuqina kukwangaphezulu; I-45 yentsimbi kunye ne-50Mn inokuxhathisa kokunxiba okufanayo; Isinyithi se-45Cr sinokuthamba phakathi kwe-T7 yentsimbi kunye ne-50Mn yentsimbi, ebonisa ukuba intsimbi ikwi-Conting Ming inokuphucula ukuxhathisa kwe-abrasion.
