Carburizingthiab nitridingyog ob txoj kev siv cov txheej txheem saum npoo hardening hauv metallurgy. Ob qho tib si txhim kho cov khoom nto ntawm cov hlau, tab sis lawv sib txawv hauv cov txheej txheem txheej txheem, cov txheej txheem kev thov, thiab cov khoom ua tau zoo.
1. Txheej txheem txheej txheem
●Carburizing:
Cov txheej txheem no suav nrog cua sovlow-carbon steel los yog alloy steelhauv acarbon nplua nuj huab cuantawm qhov kub thiab txias. Cov pa roj carbon decomposes, tso tawmactive carbon atomsuas diffuse mus rau hauv steel nto, nce nwscov ntsiab lus carbonthiab enabling tom qab hardening.
●Nitriding:
Nitriding qhiaactive nitrogen atomsnyob rau hauv lub steel nto ntawm elevated kub. Cov atoms teb nrog cov ntsiab lus alloying (xws li, Al, Cr, Mo) hauv cov hlau los tsimnyuaj nitrides, txhim kho nto hardness thiab hnav tsis kam.
2. Kub thiab sijhawm
| Parameter | Carburizing | Nitriding |
| Kub | 850 ° C - 950 ° C | 500 ° C - 600 ° C |
| Sijhawm | Ob peb mus rau kaum ob teev | Kaum mus rau pua pua teev |
Lus Cim: Nitriding tshwm sim ntawm qhov kub thiab txias tab sis feem ntau siv sij hawm ntev dua rau kev hloov kho qhov sib npaug.
3. Cov khoom ntawm cov txheej tawv tawv
Hardness thiab hnav tsis kam
●Carburizing:Achieves nto hardness ntawm58–64 HRC, muab zoo hnav tsis kam.
●Nitriding:Ua rau saum npoo hardness ntawm1000-1200 HV, feem ntau siab tshaj carburized nto, nrogzoo heev hnav tsis kam.
Kev qaug zog
●Carburizing:Txhim kho qhov tseem ceebkhoov thiab torsional qaug zog.
●Nitriding:Kuj tseem txhim khu kev qaug zog, txawm tias feem ntaumus rau qhov tsawg duatshaj carburizing.
Corrosion Resistance
●Carburizing:Tsawg corrosion kuj.
●Nitriding:Forms ibntom nitride txheej, muabsuperior corrosion kuj.
4. Cov ntaub ntawv tsim nyog
●Carburizing:
Zoo tshaj plaws raulow-carbon steel thiab low-alloy steels. Cov ntawv thov feem ntau suav nroggears, shafts, thiab cov khoomraug rau siab loads thiab kev sib txhuam.
●Nitriding:
Zoo tagnrho rau cov hlau uas muajalloying ntsiabxws li txhuas, chromium, thiab molybdenum. Feem ntau siv rauprecision cuab yeej, pwm, tuag, thiabcov khoom siv hnyav hnyav.
5. Cov yam ntxwv txheej txheem
| Yam | Carburizing | Nitriding |
| Qhov zoo | Ua ib tug sib sib zog nqus hardened txheej | Nqi-zoo Dav siv tau Tsawg distortion ** vim qhov kub thiab txias Tsis tas yuav quenching High hardness thiab corrosion kuj |
| Qhov tsis zoo | Cov txheej txheem kub yuav ua raudistortion Yuav tsum tau quenching tom qab carburizing | txheej txheem complexity nce Shallower case qhov tob Lub sijhawm voj voog ntev dua Tus nqi siab dua |
Cov ntsiab lus
| Feature | Carburizing | Nitriding |
| Hardened Txheej Qhov tob | Sib sib zog nqus | ntiav |
| Nto Hardness | Nruab nrab mus rau siab (58–64 HRC) | Siab heev (1000-1200 HV) |
| Fatigue Resistance | Siab | Nruab nrab mus rau siab |
| Corrosion Resistance | Tsawg | Siab |
| Distortion Risk | Higher (vim temps siab) | Tsawg |
| Kev kho mob tom qab | Yuav tsum tau quenching | Tsis xav tau quenching |
| Nqi | qis | Siab dua |
Ob leeg carburizing thiab nitriding muaj qhov tshwj xeeb zoo thiab raug xaiv raws li covcov cai thov, suav nrogload-bearing muaj peev xwm, seem stability, hnav tsis kam, thiabib puag ncig tej yam kev mob.
