Ke eng mekhoa ea phekolo ea mocheso

1. Mokhoa oa ts’ebetso ea anealing: Ka mor’a ho futhumatsa tšepe ho likhato tsa Ac3 + 30 ~ 50 kapa Ac1 + 30 ~ 50 likhato kapa mocheso o ka tlase ho Ac1 (boitsebiso bo loketseng bo ka botsoa), ka kakaretso u pholile butle ka mocheso oa sebōpi.

2. Mokhoa o tloaelehileng oa ts’ebetso: futhumatsa tšepe ho likhato tse 30 ~ 50 ka holimo ho Ac3 kapa Accm, ‘me ue pholisoe ka tekanyo e fokolang ea ho pholisa ho feta ho pholile ka mor’a ho boloka mocheso.

3. Mokhoa oa ts’ebetso ea ho tima: futhumatsa tšepe ka holimo ho mocheso oa phetoho ea mohato Ac3 kapa Ac1, e boloke nako e itseng, ebe oe pholisa ka potlako metsing, nitrate, oli kapa moea. Morero: Ho tima hangata ke ho fumana sebopeho sa martensitic se thata haholo. Ka linako tse ling, ha u tima litšepe tse nang le alloy tse phahameng (tse kang tšepe e sa hloekang le tšepe e sa sebetseng), ke ho fumana mohaho o le mong le o tšoanang oa austenite ho ntlafatsa ho hanyetsa ho apara. le khanyetso ea kutu.

4. Mokhoa oa ts’ebetso ea ho futhumatsa: futhumatsa tšepe e tingoeng mocheso o itseng o ka tlase ho Ac1, ‘me ue pholile moeeng kapa ka oli, metsi a chesang kapa metsi ka mor’a ho boloka mocheso.

5. Mokhoa oa ts’ebetso ea ho tima le ho futhumatsa: mocheso o phahameng oa mocheso ka mor’a ho tima o bitsoa quenching le tempering, ke hore, ho futhumatsa tšepe ho mocheso oa likhato tse 10 ~ 20 ho feta ho tima, ho tima ka mor’a ho boloka mocheso, ebe ho futhumatsa mocheso oa mocheso oa likhato tse 400 ~ 720. XNUMX ~ XNUMX likhato.

6. Mokhoa oa ts’ebetso ea botsofali: futhumatsa tšepe ho likhato tse 80 ~ 200, boloka mocheso oa lihora tse 5 ~ 20 kapa ho feta, ebe oe ntša ka sebōping ebe o o pholile moeeng. Sepheo: 1. Ho tsitsisa sebopeho sa tšepe ka mor’a ho tima, fokotsa deformation nakong ea polokelo kapa tšebeliso; 2. Fokotsa khatello ea kelello ka hare ka mor’a ho tima le ho sila, ‘me u tsitsitse sebopeho le boholo.

7. Mokhoa oa ts’ebetso oa phekolo e batang: Folisa likarolo tsa tšepe tse tingoeng ka mocheso o tlaase (joaloka leqhoa le omileng, metsi a naetrojene) ho ea ho -60 ho ea ho -80 likhato kapa ka tlase, ebe o ntša mocheso o ts’oanang ho mocheso oa kamore.

8. Mokhoa oa ts’ebetso oa ho tima lelakabe la mocheso holim’a mollo: lelakabe le tukang ka khase e tsoakiloeng ea oksijene-acetylene e fafatsoa holim’a karolo ea tšepe, ‘me e futhumala ka potlako. Ha mocheso oa ho tima o fihlile, o pholile ka ho fafatsa metsi hang-hang.

9. Induction futhumatsang holim’a quenching mokhoa oa ho sebetsa: kenya karolo ea tšepe ka har’a inductor ho hlahisa motlakase o hlahisitsoeng holim’a karolo ea tšepe, e chese mocheso oa ho tima ka nako e khutšoanyane haholo, ebe o fafatsa metsi bakeng sa ho pholile.

10. Mokhoa oa ts’ebetso ea “carburizing”: Beha tšepe ka har’a setsi sa carburizing, se chese ho likhato tse 900-950 ‘me u se boloke se futhumetse, e le hore holim’a tšepe e ka fumana lera la carburized ka mahloriso le botebo bo itseng.

11. Mokhoa oa ts’ebetso ea naetrojene: sebelisa liathomo tse sebetsang tsa naetrojene tse bolisitsoeng ke khase ea ammonia ka likhato tse 500 ho isa ho tse 600 ho etsa bokaholimo ba karolo ea tšepe e tletseng naetrojene ho etsa lera le nang le nitrided.

12. Mokhoa oa ts’ebetso ea Nitrocarburizing: carburizing le nitriding ka nako e le ‘ngoe ho ea holim’a tšepe. Morero: Ho ntlafatsa ho thatafala, ho hanyetsa ho roala, matla a mokhathala le ho hanyetsa kutu ea bokaholimo ba tšepe.
