Qhov sib txawv tseem ceeb ntawm carburizing thiab carbonitriding yog carburizing yog txheej txheem ntawm hardening steel nto siv carbon, whereas carbonitriding yog txheej txheem ntawm hardening ib steel nto siv carbon thiab nitrogen.
Hardening yog txheej txheem kev lag luam ntawm kev ua kom tawv tawv ntawm cov hlau xws li hlau. Deg hardening ntawm hlau yuav ua tau nyob rau hauv ob txoj kev: rooj hardening thiab nto hardening. Case hardening tsub kom lub hardness ntawm nto ntawm cov hlau los ntawm infusing ntsiab rau saum npoo ntawm cov khoom, ua ib tug nyias txheej ntawm ib tug harder alloy. Nyob rau hauv sib piv, nto hardening tsub kom lub hardness ntawm lub nto, thaum lub core tseem tseem mos. Surface hardening kuj muaj ob txheej txheem hu ua qhov sib txawv ntawm qhov tawv tawv thiab sib txawv hlau qauv hardening. Carburizing thiab carbonitriding yog ob txoj kev siv hauv cov txheej txheem hlau sib txawv.
Carburizing yog dab tsi?
Carburizing yog cov txheej txheem kev lag luam ntawm hardening steel nto siv carbon. Nyob rau hauv cov txheej txheem no, cov hlau alloy (steel) tau txais kev kho mob siab rau ob peb teev. Tsis tas li ntawd, qhov kev kho no yog ua nyob rau hauv ib puag ncig carbonaceous. Tsis tas li ntawd, qhov kub thiab txias peb yuav tsum tau siv rau hauv cov txheej txheem no yuav tsum yog qhov kub siab tshaj qhov kub ntawm cov hlau tseem ceeb. Ntawm no, cov hlau tuaj yeem nqus cov pa roj carbon monoxide rau hauv cov hlau los ntawm ib puag ncig carbonaceous thiab maj mam diffuse mus rau hauv cov khaubncaws sab nraud povtseg.
Ntxiv mus, qhov chaw carbonaceous uas peb siv hauv carburizing muaj xws li charcoal lossis carbon monoxide. Lub hom phiaj ntawm cov txheej txheem no yog ua kom lub ntsej muag ntawm cov hlau tawv thiab hnav-resistant. Daim ntawv thov-wise, Carburizing yog haum rau me me carbon steels. Lub sij hawm ntev carburizing nce qhov tob ntawm carbon txheej. Txawm li cas los xij, nyob rau hauv txoj kev no, qhov saum npoo yuav nyuaj dua thaum lub hauv paus tseem mos. Qee cov subcategories ntawm carburizing suav nrog pob carburizing, roj carburizing, nqus carburizing, thiab kua carburizing, nyob ntawm seb qhov txheej txheem hardening.
Carbonitriding yog dab tsi?
Carbonitriding yog cov txheej txheem kev lag luam uas muaj txiaj ntsig zoo hauv kev ua kom tawv tawv hlau siv carbon thiab nitrogen. Yog li ntawd, nws yog txheej txheem kev hloov kho saum npoo. Tsis tas li ntawd, cov txheej txheem no ua kom cov tawv tawv ntawm cov hlau thiab txo qhov hnav.
Daim duab 01: Lub cub tawg siv rau Carbonitriding
Thaum pib, hauv cov txheej txheem carbonitriding no, carbon thiab nitrogen atoms diffuse mus rau saum npoo ntawm cov hlau. Tom qab ntawd, cov atoms tsim teeb meem kom plam. Feem ntau, txoj kev carbonitriding yog pheej yig. Ntxiv mus, cov txheej txheem no zoo ib yam li cov roj carburizing txoj kev. Txawm li cas los xij, qhov txawv yog tias carburizing ntxiv tsuas yog ib puag ncig carbonaceous thaum carbonitriding siv ob qho tib si carbonaceous ib puag ncig thiab ammonia. Ntawm no, ammonia yog qhov chaw ntawm nitrogen.
Qhov txawv ntawm Carburizing thiab Carbonitriding yog dab tsi?
Carburizing thiab carbonitriding yog ob txoj kev sib txawv siv los ua kom tawv tawv. Qhov sib txawv tseem ceeb ntawm carburizing thiab carbonitriding yog carburizing yog txheej txheem ntawm hardening steel nto siv carbon, whereas carbonitriding yog txheej txheem ntawm hardening steel nto siv carbon thiab nitrogen. Tsis tas li ntawd, Carburizing koom nrog ib puag ncig carbonaceous, thaum carbonitriding koom nrog ib puag ncig carbonaceous nrog ammonia gas.
Ntxiv mus, lwm qhov sib txawv ntawm carburizing thiab carbonitriding yog tias carbonitriding yog qhov sib piv kim dua carburizing.
Summary – Carburizing vs Carbonitriding
Hauv luv luv, carburizing thiab carbonitriding yog ob txoj kev siv hauv cov txheej txheem hlau sib txawv. Qhov sib txawv tseem ceeb ntawm carburizing thiab carbonitriding yog carburizing yog txheej txheem ntawm hardening steel nto siv carbon, whereas carbonitriding yog txheej txheem ntawm hardening ib steel nto siv carbon thiab nitrogen.
