Carburizing vs nitriding

Carburizing thiab nitriding yog ob qho tib si tseem ceeb ntawm cov txheej txheem tawv tawv hauv metallurgy, nrog rau cov hauv qab no sib txawv:
Cov Ntsiab Cai ntawm Cov Txheej Txheem

•Carburizing: Nws cuam tshuam txog kev ua kom cov hlau uas muaj cov pa roj carbon tsawg lossis cov hlau uas muaj cov pa roj carbon tsawg sov rau hauv cov khoom nruab nrab uas muaj cov pa roj carbon ntau ntawm qee qhov kub. Cov pa roj carbon uas tau los ntawm cov pa roj carbon yuav lwj mus ua cov pa roj carbon uas ua haujlwm, uas raug nqus los ntawm cov hlau nto thiab nthuav mus rau sab hauv, ua rau cov pa roj carbon ntawm cov hlau nto ntau ntxiv.
•Nitriding: Nws yog cov txheej txheem uas tso cai rau cov atoms nitrogen uas nquag nkag mus rau saum npoo ntawm cov hlau ntawm qee qhov kub, tsim cov txheej nitride. Cov atoms nitrogen react nrog cov khoom sib xyaw hauv cov hlau los tsim cov nitrides uas muaj zog thiab tiv taus kev hnav zoo.
Kub thiab Lub Sijhawm ntawm Cov Txheej Txheem

•CarburizingFeem ntau, qhov kub thiab txias yog nruab nrab ntawm 850 ° C thiab 950 ° C. Cov txheej txheem siv sijhawm ntev heev, feem ntau yog ntau txog ntau teev, nyob ntawm qhov tob ntawm cov txheej carburized.
•NitridingQhov kub thiab txias tsis tshua muaj, feem ntau ntawm 500 ° C thiab 600 ° C. Lub sijhawm kuj ntev tab sis luv dua li ntawm carburizing, feem ntau yog kaum ob txog ntau pua teev.
Cov Khoom ntawm Cov Txheej Nkag Mus

•Kev Nyuaj Siab thiab Kev Hnav Tsis Taus

•CarburizingQhov nyuaj ntawm cov hlau tom qab carburizing tuaj yeem ncav cuag 58-64 HRC, qhia txog qhov nyuaj thiab hnav tsis kam.
•NitridingTom qab nitriding, qhov nyuaj ntawm cov hlau tuaj yeem ncav cuag 1000-1200 HV, uas siab dua li ntawm carburizing, nrog kev hnav zoo dua.
•Lub zog qaug zog

•Carburizing: Nws tuaj yeem txhim kho lub zog qaug zog ntawm cov hlau, tshwj xeeb tshaj yog nyob rau hauv kev khoov thiab torsional qaug zog.
•Nitriding: Nws kuj tseem tuaj yeem txhim kho lub zog qaug zog ntawm cov hlau, tab sis cov nyhuv tsis muaj zog dua li ntawm carburizing.
•Kev Tiv Thaiv Kev Xeb

•Carburizing: Qhov kev tiv thaiv corrosion tom qab carburizing yog qhov tsis zoo.
•Nitriding: Ib txheej nitride tuab yog tsim rau ntawm qhov chaw hlau tom qab nitriding, uas muab kev tiv thaiv corrosion zoo dua.
Cov Khoom Siv Tau

•Carburizing: Nws yog qhov tsim nyog rau cov hlau qis-carbon thiab cov hlau alloy qis-carbon, thiab feem ntau yog siv rau hauv kev tsim cov iav, shafts thiab lwm qhov chaw uas dais cov khoom loj thiab kev sib txhuam.
•NitridingNws yog qhov tsim nyog rau cov hlau uas muaj cov khoom sib xyaw xws li txhuas, chromium thiab molybdenum. Nws feem ntau yog siv los tsim cov khoom siv siab thiab tiv taus kev hnav, xws li pwm thiab cov cuab yeej ntsuas.
Cov yam ntxwv ntawm cov txheej txheem

•Carburizing

•Cov txiaj ntsig: Nws tuaj yeem tau txais ib txheej carburized tob tob, txhim kho lub peev xwm thauj khoom ntawm cov khoom. Cov txheej txheem yooj yim thiab tus nqi qis.
• Qhov Tsis Zoo: Qhov kub ntawm kev ua kom kub hnyiab siab heev, uas ua rau qhov chaw puas yooj yim. Kev kho cua sov xws li kev quenching yog qhov yuav tsum tau ua tom qab ua kom kub hnyiab, ua rau cov txheej txheem nyuaj dua.
•Nitriding

• : Qhov kub ntawm nitriding qis, ua rau muaj qhov deformation tsawg dua. Nws tuaj yeem ua tiav qhov nyuaj siab, tiv taus kev hnav zoo thiab tiv taus corrosion. Tsis tas yuav tsum tau quenching tom qab nitriding, ua kom yooj yim rau cov txheej txheem.
•Qhov tsis zoo: Cov txheej nitrided yog nyias, nrog rau lub peev xwm thauj khoom tsawg. Lub sijhawm nitriding ntev thiab tus nqi siab.
