Nitriding yog txheej txheem kho cua sov uas diffuses nitrogen rau saum npoo ntawm cov hlau los tsim cov ntaub ntawv tawv tawv. Cov txheej txheem no feem ntau yog siv rau ntawm qis-alloy steels. Lawv kuj tau siv rau ntawm titanium, aluminium thiab molybdenum.
Qhov txawv ntawm nitriding thiab carburizing yog dab tsi?
Carburizing thiab Nitriding yog ob txoj kev siv hauv cov txheej txheem hlau sib txawv. Qhov sib txawv tseem ceeb ntawm carburizing thiab Nitriding yog tias hauv carburizing, carbon yog diffused rau steel nto whereas, nyob rau hauv cov txheej txheem Nitriding, nitrogen yog diffused rau steel nto.
Nitriding nce hardness li cas?
Nitriding yog kev kho mob ntsig txog qhov chaw (daim duab 3) nrog lub hom phiaj txhawm rau nce qhov tawv tawv (nrog rau lwm yam khoom) los ntawm kev tsim cov rooj plaub ntawm qhov chaw (Fig. 4). Ib qho kev thov rov hais dua ntawm cov txheej txheem no yog tias tsis tas yuav quenching sai.
Nitriding ua li cas?
Nitriding feem ntau yog ua los ntawm cua sov cov khoom hlau hauv cov pa roj ammonia (NH 3) ntawm qhov kub ntawm 500 txog 550 ° C (950 thiab 1, 050 ° F) rau lub sijhawm 5 txog 100 teev, nyob ntawm qhov xav tau qhov tob ntawm qhov sib txawv ntawm cov nitrogen.
Nitriding qhov zoo yog dab tsi?
Qhov zoo thiab qhov tsis zoo ntawm Nitriding
- zoo khaws cia ntawm qhov hnyav ntawm qhov kub siab.
- Kev qaug zog ntau duanyob rau hauv corrosive tej yam kev mob.
- Tsawg warping lossis distortion ntawm cov lauj kaub kho.
- Higer endurance txwv nyob rau hauv dabtsi yog khoov stresses.
- Ntau dua tiv thaiv hnav thiab corrosion.
- Ntau dua qhov tawv tawv.
