Ukumelana okuphezulu kokugqoka kwensimbi e-carburized kungenxa yokuqukethwe kwekhabhoni ephezulu kungqimba olungaphezulu. Lapho i-carbon steel w (C) ingaphansi kuka-0.43%, ingxenye e-carburized inenzuzo ekumelaneni kokugqoka, futhi lapho w (C) Uma ingaphezulu kuka-0.45%, ukumelana nokugqoka kwezingxenye eziqinisiwe zokungeniswa kuyathuthukiswa. Lesi yisiphetho sokuthi i-TH HACAHOBA idonse ngokuya ngokuhlolwa kwenkambu kwephini lethrekhi. Ngakho-ke, iphini yethrekhi yogandaganda ithathelwa indawo yinqubo entsha yokuqinisa insimbi yensimbi engama-50. . Ukuqhathaniswa kokumelana nokugqoka kwama-w (C) wensimbi ahlukile ngemuva kokucinywa kokungeniswa kukhombisa ithonya lokwakheka kwensimbi. Imininingwane esetafuleni ifakazela ukuthi insimbi ye-T7 inenani elincane kakhulu lokugqoka, futhi okuqukethwe yikhabhoni nobulukhuni nakho kuphezulu kakhulu; Insimbi engu-45 kanye no-50Mn inokuqina kokugqoka okufanayo; Insimbi engu-45Cr inokumelana nokuguga phakathi kwensimbi ye-T7 nensimbi engu-50Mn, okukhombisa ukuthi insimbi eku-Conting Ming ingathuthukisa ukumelana nomhuzuko.
