Hom tshuaj no muaj xws li cov roj carbon nitrate, nitrogen, nitriding carbon, nitric oxygen, sulfur nitriding thiab sulfur nitriding. Cov txheej txheem kev kho no yog yooj yim, muaj zog adaptability, muaj zog permeability tsawg kub (480 ~ 600 ℃), me me deformation, tshwj xeeb tshaj yog hloov mus rau precision pwm ntim zuj zus, thiab nitride txheej nrog lub siab tawv, wearability, zoo antisticking properties.3 cr2w8v steel tuag casting pwm, tom qab tempering, 520 ~ 540 ℃ tom qab nitrriding, tsawg dua nitride pwm kev ua hauj lwm nce 2 ~ 3 zaug.Tau ua ntawm H13 steel tuag casting pwm, ntau daim ntawm cov roj nitritic, thiab nitriding li ntawm tempering, tawv hardness rau HRC65 ~ 70, thiab cov sab nrauv pwm tseem ceeb thiab toughness, zoo kom tau zoo mechanical properties.Nitriding txheej txheem ntawm tuag casting mould ntom kho feem ntau siv, tab sis thaum nitride txheej tau nyias thiab crisp dawb txheej, tsis muaj peev xwm tiv taus cov nyhuv ntawm kev thermal siab, yooj yim los ua cov kab tawg, txo cov thermal qaug zog kuj.Yog li ntawd, nyob rau hauv tus txheej txheem ntawm nitriding, txoj kev yuav tsum nruj me ntsis controll ed kom tsis txhob muaj cov txheej txhaws ntawm txheej txheem.Recently, theem nrab thiab ntau lub nitriding kev tau npaj tau nyob hauv lub teb chaws txawv teb chaws.Kev dua nitriding yuav tau ua nyob rau hauv tus txheej txheem ntawm cov kev pab cuam tau decomposed yooj yim micro tawg ntawm nitrides dawb txheej, nce lub nitriding txheej thickness , thiab tib lub sij hawm ua rau cov pwm ntawm cov txheej txheem ntxhov siab ploj yog tuab heev, muab lub neej pwm los txhim kho kom zoo dua.Thiab ntxiv, ntsev-da dej carbonitriding thiab cov ntsev-da dej sulfur-nitrogen carburizing kuj tau txais los ntawm cov kev sib xyaw no. siv hauv cov teb chaws txawv teb chaws. Piv txwv, TFI + ABI txheej txheem siv ntau dav siv nyob rau hauv Suav teb, uas yog soak hauv alkaline oxidizing ntsev da dej tom qab nitric carburising hauv ntsev da dej.Cov ntsa ntawm lub workpiece oxidized thiab dub, thiab nws txoj kev tiv thaiv, corrosion kuj thiab tshav kub tau raug kho dua.Qhov tuag - casting tuag lub neej ntawm txhuas txhuam los ntawm cov qauv no tau nce los ntawm ntau pua lub sij hawm.Piv txwv li, oxynit txheej txheem tsim nyob rau Fabkis rau nitrogenation tom qab sulfur thiab nitrogen carburization yog ntau yam ntxwv rau non-ferrous hlau tuag casting pwm.
