Ngesikhathi sokucubungula isikhunta Ukwelashwa kokushisa okungalungile kuzoholela ekuqhekekeni kwesikhunta kanye nokuchithwa ngaphambi kwesikhathi, ikakhulukazi uma kusetshenziswa kuphela ukucisha nokushisa, ngaphandle kokucisha, bese inqubo ye-nitriding engaphezulu, ukuqhekeka komhlaba kanye nokuqhekeka kuzokwenzeka ngemva kwezinkulungwane zezikhathi zokufa.
Ungabona ezinye izidingo zansuku zonke kanye nezidingo zansuku zonke yonke indawo empilweni. Lezi zidingo zansuku zonke zenziwe ngobuhle kakhulu. Kuyaziwa ukuthi kunezidingo zansuku zonke ezinenani elikhulu kakhulu.
Kusukela esihlokweni sesisekelo sesikhunta esingajwayelekile, singakwazi ukwazi ukuthi lokhu kufanele kube umkhiqizo wesisekelo sesikhunta. Ngesikhathi esifanayo, wonke umuntu kufanele akwazi ukuthola esihlokweni saso ukuthi lokhu kufanele kube isisekelo sesikhunta esikhethekile kakhulu.
Isisekelo sesikhunta siwumkhiqizo ophelile we-mold, owakhiwe ngamapuleti ensimbi ahlukahlukene anezingxenye ezifanayo, okungashiwo ukuthi yi-skeleton yesikhunta sonke.
Uhlukanisa isikhunta ngokwesayensi, uthuthukise imboni yesikhunta ngendlela ehleliwe, ucwaninge ngendlela ehlelekile futhi uthuthukise ubuchwepheshe bokukhiqiza isikhunta, futhi ucwaninge futhi wenze amazinga obuchwepheshe besikhunta.
Manje imboni yokukhiqiza isikhunta isivuthiwe impela. Ngaphezu kokuthenga izisekelo zesikhunta ezenziwe ngokwezifiso ngokuya ngezidingo zesikhunta ngasinye, abakhiqizi besikhunta bangaphinda bakhethe imikhiqizo yesisekelo sesikhunta esimisiwe.
