Qhov sib txawv tseem ceeb ntawm cyaniding thiab carbonitriding yog tias cyaniding siv sodium cyanide kua, thaum cov txheej txheem carbonitriding siv cov cua kub uas muaj cov ammonia thiab hydrocarbons.
Cov txheej txheem tawv tawv yog qhov tawv tawv ntawm cov hlau nplaum thaum tso cai rau qhov sib sib zog nqus hauv qab ntawm cov hlau kom nyob twj ywm mos, thiab cov txheej txheem no tsim ib txheej nyias ntawm cov hlau nyuaj ntawm qhov chaw. Muaj cov txheej txheem sib txawv ntawm cov txheej txheem tawv tawv, suav nrog cyaniding, carbonitriding, carburizing, nitriding, nplaim taws lossis induction hardening, thiab ferric nitrocarburizing.
Cyaniding yog dab tsi?
Cyaniding yog hom txheej txheem tawv tawv uas siv sodium cyanide. Qhov no yog cov txheej txheem ceev heev thiab muaj txiaj ntsig uas yog qhov tseem ceeb ntawm cov pa roj carbon tsawg. Hauv cov txheej txheem no, peb yuav tsum ua kom sov cov khoom siv hlau los yog ib feem ntawm nws ntawm qhov kub thiab txias hauv da dej ntawm sodium cyanide. Tom qab ntawd, peb yuav tsum tau tua cov hlau, tom qab ntawd yaug nws hauv dej lossis roj txhawm rau tshem tawm cov sodium cyanide seem ntawm cov hlau.
Feem ntau, cov txheej txheem cyaniding ua rau nyias nyias nyias. Tab sis lub plhaub no nyuaj dua li lub plhaub ua los ntawm cov txheej txheem carburizing. Tsis tas li ntawd, cov txheej txheem no tsuas siv li 20 mus rau 30 feeb xwb kom tiav. Peb tuaj yeem siv cov txheej txheem no feem ntau ntawm cov khoom me me, suav nrog bolts, ceev, screws thiab cov iav me me. Txawm li cas los xij, muaj qhov cuam tshuam loj ntawm cov txheej txheem cyaniding, uas yog, cov cyanide uas peb siv hauv cov txheej txheem no yog tshuaj lom heev.
Carbonitriding yog dab tsi?
Carbonitriding yog ib hom ntawm cov ntaub ntawv hardening nyob rau hauv uas ib tug gaseous cua yog siv rau cov txheej txheem hardening. Peb tuaj yeem soj ntsuam tias cov txheej txheem carbonitriding zoo ib yam li cov txheej txheem cyaniding, tshwj tsis yog cov txheej txheem no siv cov pa cua.
Daim duab 01: Carbonitriding rauv
Cov huab cua uas peb siv tau hauv cov txheej txheem no suav nrog ammonia thiab hydrocarbon gases. Qhov ntsuas kub uas peb yuav tsum tau ua kom sov cov khoom siv hlau los yog ib feem nyob ntawm cov kauj ruam kawg; Yog tias peb yuav tua cov hlau saum npoo, ces qhov kub yuav tsum nyob ib ncig ntawm 445 txog 885 degrees Celsius. Yog tias peb tsis mus tua cov hlau saum npoo, ces qhov kub yuav nyob ib puag ncig 649 txog 788 Celsius degrees.
Qhov txawv ntawm Cyaniding thiab Carbonitriding yog dab tsi?
Cyaniding thiab carbonitriding yog ob hom txheej txheem txheej txheem tawv tawv uas muaj txiaj ntsig zoo kom tau txais cov tawv tawv ntawm cov hlau. Qhov sib txawv tseem ceeb ntawm cyaniding thiab carbonitriding yog tias cyaniding siv sodium cyanide kua, thaum cov txheej txheem carbonitriding siv cov cua kub uas muaj ammonia thiab hydrocarbons. Ntxiv mus, cyaniding muaj qhov kub ntawm 871 txog 954 degrees Celsius. Tab sis nyob rau hauv carbonitriding, yog hais tias peb yuav quench cov khoom kub yuav tsum nyob ib ncig ntawm 445 mus rau 885 degrees Celsius thiab yog hais tias peb yuav tsis mus quench lub hlau nto ces qhov kub yuav nyob ib ncig ntawm 649 mus rau 788 degrees.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm cyaniding thiab carbonitriding.
Summary – Cyaniding vs Carbonitriding
Cyaniding thiab carbonitriding yog ob hom txheej txheem txheej txheem tawv tawv uas muaj txiaj ntsig zoo kom tau txais cov tawv tawv ntawm cov hlau. Qhov sib txawv tseem ceeb ntawm cyaniding thiab carbonitriding yog tias cyaniding siv sodium cyanide kua, thaum cov txheej txheem carbonitriding siv cov cua kub uas muaj ammonia thiab hydrocarbons. Nyob rau hauv lwm yam lus, rooj plaub hardening nyob rau hauv cov txheej txheem cyaniding tshwm sim nyob rau hauv ib tug ua kua da dej, thaum lub rooj plaub hardening tshwm sim nyob rau hauv lub xub ntiag ntawm gases.
