3. Tharollo e tiileng ea phekolo ea mocheso:
Mokhoa oa phekolo ea mocheso oo motsoako o futhumatsang mocheso o phahameng 'me o bolokoa ka mocheso o sa khaotseng sebakeng se le seng sa mokhahlelo o le mong ho qhaqha ka ho feletseng karolo e feteletseng ka tharollo e tiileng, ebe e pholile ka potlako ho fumana tharollo e tiileng ea supersaturated.
4. Botsofali:
Ka mor'a hore motsoako o be le tharollo e tiileng ea mocheso oa mocheso kapa deformation e batang ea polasetiki, thepa ea eona e fetoha ha nako e behoa mocheso oa kamore kapa ka holim'a mocheso oa kamore.
5. Kalafo ea tharollo e tiileng:
Qhala ka botlalo mekhahlelo e fapaneng ea alloy, matlafatsa tharollo e tiileng le ho ntlafatsa ho tiea le ho hanyetsa kutu, ho felisa khatello ea maikutlo le ho nolofatsa, e le ho tsoela pele ho sebetsa le ho theha.
6. Phekolo ea botsofali:
Ho futhumatsa le ho tšoara mocheso moo mohato o matlafatsang o ntseng o eketseha, e le hore mohato oa ho matlafatsa o fokotsehe le ho thatafala, ho ntlafatsa matla.
7. Ho tima:

8. Ho halefisa:
Ts'ebetso ea kalafo ea mocheso eo mochini o timang o futhumatsang mocheso o loketseng ka tlase ho ntlha ea bohlokoa ea AC1 ka nako e itseng, ebe o pholile o sebelisa mokhoa o fihlelang litlhoko tsa ho fumana sebopeho le thepa e hlokahalang.
9. Carbonitriding ea tšepe:
Carbonitriding ke mokhoa oa ho kenya carbon le naetrojene ka nako e le 'ngoe karolong e ka holimo ea tšepe. Ka tloaelo, carbonitriding e boetse e bitsoa cyanidation. Hajoale, khase ea carbonitriding ea mocheso o mahareng le mocheso o tlase oa carbonitriding (ke hore, nitriding ea khase e bonolo) e sebelisoa haholo. Morero o ka sehloohong oa mocheso o mahareng oa khase carbonitriding ke ho ntlafatsa ho thatafala, ho hanyetsa le ho khathala matla a tšepe. Mocheso o tlase oa khase carbonitriding haholo-holo ke nitriding, 'me morero oa eona o ka sehloohong ke ho ntlafatsa ho hanyetsa le ho haptjoa ha tšepe ea tšepe.
10. Ho tima le ho kokobetsa:
Ka kakaretso ke tloaelo ho kopanya ho tima le mocheso o phahameng oa mocheso e le phekolo ea mocheso e bitsoang quenching le tempering. Phekolo ea ho tima le ho futhumatsa e sebelisoa haholo likarolong tse sa tšoaneng tsa meralo, haholo-holo lithupa tse hokelang, liboutu, likere le li-shaft tse sebetsang tlas'a meroalo e fapanyetsanang. Ka mor'a ho tima le ho futhumatsa phekolo, ho fumanoa sebopeho sa sorbite se halefileng, 'me thepa ea eona ea mechine e molemo ho feta ea sebopeho se tloaelehileng sa sorbite se nang le boima bo tšoanang. Ho thatafala ha eona ho itšetlehile ka mocheso o phahameng oa mocheso oa mocheso 'me o amana le botsitso ba tšepe ea tšepe le boholo ba karolo ea cross-sectional ea workpiece, hangata pakeng tsa HB200-350.
11. Brazing:
Ts'ebetso ea kalafo ea mocheso e sebelisang lisebelisoa tsa brazing ho kopanya likarolo tse peli tsa mosebetsi hammoho.
