Carburizingthiab kev ua kom nitridingyog ob txoj kev siv dav dav los ua kom tawv ntawm qhov chaw hauv metallurgy. Ob qho tib si txhim kho cov yam ntxwv ntawm qhov chaw ntawm cov hlau, tab sis lawv txawv ntau hauv cov ntsiab cai ntawm cov txheej txheem, cov xwm txheej ntawm kev siv, thiab cov yam ntxwv ntawm cov khoom siv.
1. Cov Ntsiab Cai ntawm Cov Txheej Txheem
●Carburizing:
Cov txheej txheem no suav nrog cua sovcov hlau uas tsis muaj carbon los yog cov hlau alloynyob rau hauv ib qhohuab cua nplua nuj carbonthaum kub heev. Cov pa roj carbon decomposes, tso tawmcov pa roj carbon uas ua haujlwmuas kis mus rau hauv qhov chaw hlau, ua rau nws nce ntxivcov ntsiab lus carbonthiab ua kom tawv tom qab.
●Nitriding:
Nitriding qhia txogcov pa roj nitrogen uas ua haujlwmrau hauv qhov chaw hlau ntawm qhov kub siab. Cov atoms no react nrog cov ntsiab lus alloying (piv txwv li, Al, Cr, Mo) hauv cov hlau los tsimcov nitride nyuaj, txhim kho qhov tawv ntawm qhov chaw thiab kev hnav tsis kam.
2. Kub thiab Sijhawm
| Cov Qauv | Carburizing | Nitriding |
| Kub | 850°C – 950°C | 500°C – 600°C |
| Lub Sijhawm | Ntau mus txog kaum ob teev | Kaum ob mus rau ntau pua teev |
Lus Cim: Nitriding tshwm sim ntawm qhov kub qis dua tab sis feem ntau siv sijhawm ntev dua rau kev hloov kho qhov chaw sib npaug.
3. Cov Khoom ntawm Cov Txheej Uas Tau Khoov
Kev Nyuaj Siab thiab Kev Hnav Tsis Taus
●Carburizing:Ua tiav qhov nyuaj ntawm qhov chaw58–64 HRC, muab kev tiv thaiv zoo hnav.
●Nitriding:Cov txiaj ntsig ntawm qhov nyuaj ntawm1000–1200 HV, feem ntau siab dua li cov chaw carburized, nrogkev hnav tsis kam zoo heev.
Lub zog qaug zog
●Carburizing:Zoo dua qublub zog khoov thiab torsional qaug zog.
●Nitriding:Tseem ua rau lub zog qaug zog ntxiv, txawm tias feem ntaurau qhov tsawg duadua li carburizing.
Kev Tiv Thaiv Kev Xeb
●Carburizing:Kev tiv thaiv corrosion tsawg.
●Nitriding:Cov ntaub ntawv atxheej nitride ntom ntom, muabkev tiv thaiv corrosion zoo dua.
4. Cov Khoom Siv Tsim Nyog
●Carburizing:
Zoo tshaj plaws raucov hlau uas tsis muaj carbon thiab cov hlau uas tsis muaj alloyCov ntawv thov feem ntau suav nrogcov iav, cov shafts, thiab cov khoom sib xyawraug rau cov loads siab thiab kev sib txhuam.
●Nitriding:
Zoo tagnrho rau cov hlau uas muajcov ntsiab lus sib xyawxws li txhuas, chromium, thiab molybdenum. Feem ntau siv raucov cuab yeej precision, pwm, tuag, thiabcov khoom siv hnav siab.
5. Cov yam ntxwv ntawm cov txheej txheem
| Aspect | Carburizing | Nitriding |
| Cov txiaj ntsig | Tsim ib txheej tawv tob tob | Tus nqi tsim nyog Siv tau dav Kev cuam tshuam tsawg** vim qhov kub qis dua Tsis tas yuav tsum tau quenching Kev kub siab thiab kev tiv thaiv corrosion |
| Qhov tsis zoo | Cov txheej txheem kub siab yuav ua raukev cuam tshuam Yuav tsum tau quenching tom qab carburizing | Cov txheej txheem nyuaj zuj zus Qhov tob ntawm rooj plaub qis dua Lub sijhawm voj voog ntev dua Tus nqi siab dua |
Kev Txheeb Xyuas
| Feature | Carburizing | Nitriding |
| Qhov tob ntawm txheej tawv | Sib sib zog nqus | Tsis tob |
| Qhov nyuaj ntawm qhov chaw | Nruab nrab mus rau siab (58–64 HRC) | Siab heev (1000–1200 HV) |
| Kev Tiv Thaiv Kev Qaug Zog | Siab | Nruab nrab mus rau siab |
| Kev Tiv Thaiv Kev Xeb | Qis | Siab |
| Kev Pheej Hmoo ntawm Kev Hloov Pauv | Kub heev (vim yog huab cua sov heev) | Qis |
| Kev kho mob tom qab | Yuav tsum tau quenching | Tsis tas yuav tsum tau quenching |
| Tus nqi | Qis dua | Siab dua |
Ob qho tib si carburizing thiab nitriding muaj cov txiaj ntsig tshwj xeeb thiab raug xaiv raws licov kev cai thov, suav nrogmuaj peev xwm nqa tau, ruaj khov ntawm qhov ntev, tiv taus kev hnav, thiabtej yam kev mob ib puag ncig.
