Carburizing vs nitrividing

Carburizing thiab nitrividing yog ob qho tseem ceeb saum npoo tawv teeb hauv metallurgy, nrog cov sib txawv hauv qab no:
Cov ntsiab cai txheej txheem

•Carburizing: Nws cuam tshuam nrog cov cua sov cov hlau roj carbon tsawg lossis cov roj av tsis huv Cov pa roj carbon qhov system los tsim cov roj carbon atoms, uas yog nqus los ntawm cov hlau nto thiab diffuse sab hauv, nce cov roj carbon cov ntsiab lus ntawm cov hlau nto.
•Nitriving: Nws yog tus txheej txheem ntawm kev tso cai rau cov neeg muaj cov atoms kom nkag rau saum npoo hlau ntawm ib txheej kub, sib sau cov txheej nitride. Nitrogen atoms refle nrog alloying cov ntsiab hauv cov hlau los tsim cov nitrides nrog lub siab tawv thiab hnav tsis kam.
Cov txheej txheem kub thiab sijhawm

•Carburizing: Qhov ntsuas kub feem ntau ntawm 850 ° C thiab 950 ° C. Cov txheej txheem yuav siv sijhawm ntev, feem ntau yog ob peb los kaum ob teev, nyob ntawm qhov yuav tsum yog qhov tob ntawm carburized txheej.
•Nitriving: Qhov kub yog tus nqi qis, feem ntau ntawm 500 ° C thiab 600 ° C. Lub sijhawm tseem ntev tab sis luv dua li ntawm carburizing, feem ntau kaum tawm rau ntau pua teev.
Cov yam ntxwv ntawm cov txheej nkag

•Hardness thiab hnav tsis kam

•Carburizing: Lub saum npoo hardness ntawm cov hlau tuaj yeem ncav cuag 58-64 hrc tom qab carburizing, qhia lub hardness thiab hnav tsis kam.
•Nitriving: Lub saum npoo hardness ntawm cov hlau tuaj yeem ncav cuag 1000-1200 hV tom qab nitriving, uas yog siab tshaj qhov ntawm carburizing, nrog kev coj zoo dua.
•Qaug zog muaj zog

•Carburizing: Nws tuaj yeem txhim kho kev qaug zog dag zog ntawm cov hlau, tshwj xeeb tshaj yog hauv kev khoov thiab torsional qaug zog.
•Nitriving: Nws tseem tuaj yeem txhim kho lub zog nkees ntawm cov hlau, tab sis cov nyhuv yog qhov tsis muaj zog tshaj li ntawm carburizing.
•Corrosion Kuj

•Carburizing: Cov corrosion tsis kam tom qab carburizing tsis zoo.
•Nitriving: Txheej nitride nitride yog tsim rau ntawm cov hlau saum toj tom qab nitrivon tom qab nitrival, uas muab kev tiv thaiv corrosion zoo dua.
Siv tau cov ntaub ntawv

•Carburizing: Nws yog qhov haum rau cov hlau tsis muaj roj carbon thiab cov roj av tsis huv
•Nitriving: Nws yog qhov haum rau cov hlau uas muaj cov alloying xws li txhuas, chromium thiab molybdenum. Nws yog feem ntau siv los tsim HAL-precision thiab high-hnav-resistant seem, xws li pwm thiab ntsuas cov cuab yeej thiab ntsuas cov cuab yeej thiab ntsuas cov cuab yeej thiab ntsuas cov cuab yeej thiab ntsuas cov cuab yeej.
Txheej Txheem Cov yam ntxwv

•Carburizing

•Qhov Zoo: Nws tuaj yeem tau txais ib qho kev sib sib zog ntawm carburized txheej, txhim kho cov load-coj tau muaj peev xwm ntawm qhov chaw. Cov txheej txheem yooj yim kuj yooj yim thiab tus nqi yog tsawg.
• Qhov tsis zoo: Lub carburizes kub yog qhov siab, uas tuaj yeem yooj yim ua rau muaj kev sib txawv. Kev kho cua sov xws li quenching yog yuav tsum tau tom qab carburizing, nce cov txheej txheem nyuaj.
•Nitriving

•: Cov nitriding kub yog tsawg, ua rau muaj kev tawm tsam tsawg. Nws tuaj yeem ua tiav lub siab tawv, hnav tsis kam thiab corrosion tsis kam. Tsis tas yuav tsum quenching tom qab nitrived, sim kom yooj yim txheej txheem.
•Tsis zoo: Cov txheej nitrided yog nyias, nrog lub peev xwm tsis tshua muaj peev xwm. Lub sij hawm nitriving yog ntev thiab tus nqi yog siab.
