Carburizing thiab Nitriding

Dab tsi yog Carburizing thiab Nitriding

Kev Siv Lub Tshuab Nqus Tsev Carburizing nrog Acetylene (AvaC)

Cov txheej txheem nqus tsev vacuum carburizing ntawm AvaC yog ib txoj kev siv tshuab uas siv acetylene los tshem tawm qhov teeb meem ntawm cov pa luam yeeb thiab cov roj av uas paub tias tshwm sim los ntawm propane, thaum ua rau muaj zog carburizing ntau dua txawm tias rau cov qhov tsis pom lossis cov qhov los ntawm.

Ib qho ntawm cov txiaj ntsig tseem ceeb tshaj plaws ntawm cov txheej txheem AvaC yog muaj cov pa roj carbon ntau, ua kom muaj kev sib xyaw ua ke zoo heev txawm tias rau cov qauv geometries thiab cov khoom siv thauj khoom siab heev. Cov txheej txheem AvaC cuam tshuam nrog kev txhaj tshuaj acetylene (boost) thiab cov roj nruab nrab, xws li nitrogen, rau kev sib kis. Thaum lub sijhawm txhaj tshuaj boost, acetylene tsuas yog yuav tawg thaum sib cuag nrog cov hlau tag nrho uas tso cai rau kev sib xyaw ua ke.

Qhov txiaj ntsig zoo tshaj plaws rau AvaC tuaj yeem pom thaum cov pa roj hydrocarbon sib txawv rau kev siv carburizing qis-siab raug soj ntsuam rau lawv lub zog nkag mus rau hauv cov qhov me me, ntev, qhov muag tsis pom. Kev siv lub tshuab nqus tsev carburizing nrog acetylene ua rau muaj kev cuam tshuam carburizing tag nrho raws li qhov ntev ntawm lub qhov vim tias acetylene muaj peev xwm carburizing sib txawv kiag li dua li ntawm propane lossis ethylene.

Cov txiaj ntsig ntawm cov txheej txheem AvaC:

Muaj peev xwm ua haujlwm tau zoo tas mus li

Kev lees paub qhov rov ua dua ntawm cov txheej txheem

Kev xa tawm roj acetylene zoo tshaj plaws

Qhib, yooj yim txij nkawm-dawb modular system

Kev hloov pauv carbon ntau ntxiv

Txo lub sijhawm ua haujlwm

Txhim kho microstructure, kev tiv thaiv kev ntxhov siab ntau dua, thiab qhov zoo dua ntawm qhov chaw

Kev nthuav dav ntawm kev lag luam rau kev nce peev xwm

Ntau yam kev muaj peev xwm quenching nrog helium, nitrogen, cov roj sib xyaw, lossis roj

Cov txiaj ntsig zoo dua li cov cua sov hauv huab cua:

Ib puag ncig ua haujlwm zoo dua nrog kev tsim phab ntsa txias, uas ua rau lub plhaub kub qis dua

Tsis tas yuav muaj cov kaus mom kim heev lossis cov pawg khoom kim heev

Kev pib ua haujlwm thiab kaw sai dua

Tsis tas yuav tsum muaj cov tshuab hluav taws xob endothermic

Cov cub tawg uas siv roj quench xav tau qhov chaw hauv pem teb tsawg dua thiab tsis tas ntxuav tom qab kom tshem tawm cov roj quench

Tsis tas yuav muaj qhov av lossis cov kev cai tshwj xeeb rau lub hauv paus

Carbonitriding

Carbonitriding yog ib qho txheej txheem hardening zoo ib yam li carburizing, nrog rau kev ntxiv nitrogen, siv los ua kom muaj kev tiv thaiv kev hnav thiab qhov nyuaj ntawm qhov chaw. Piv rau carburizing, qhov kev sib kis ntawm ob qho tib si carbon thiab nitrogen ua rau muaj kev tawv ntawm cov hlau carbon dawb thiab cov hlau tsis tshua muaj hlau.

Cov ntawv thov ib txwm muaj xws li:cov iav thiab cov shaftscov pistonscov menyuam thiab cov kabmobcov levers hauv hydraulic, pneumatic thiab mechanical actuated systems.

Cov txheej txheem carbonitriding qis siab (AvaC-N) siv acetylene thiab ammonia. Ib yam li carburizing, qhov tshwm sim muaj lub thawv tawv, tsis yooj yim hnav. Txawm li cas los xij, tsis zoo li AvaC carburizing, qhov tob ntawm nitrogen thiab carbon yog nruab nrab ntawm 0.003″ thiab 0.030″. Vim tias nitrogen ua rau cov hlau tawv dua, cov txheej txheem no tsim cov khoom nrog kev tawv ntxiv hauv qhov tob ntawm lub thawv. Vim tias carbonitriding ua tiav ntawm qhov kub qis dua me ntsis dua li carburizing, nws kuj txo qhov kev cuam tshuam los ntawm kev quenching.

Nitriding thiab Nitrocarburizing

Nitriding yog ib qho txheej txheem ua kom tawv uas ua rau nitrogen kis mus rau saum npoo ntawm cov hlau, feem ntau yog cov hlau uas muaj carbon tsawg, cov hlau uas tsis muaj alloy ntau. Nws kuj tseem siv rau cov hlau uas muaj carbon nruab nrab thiab siab, titanium, txhuas thiab molybdenum.

Nitrocarburizing yog ib qho kev hloov pauv me me ntawm cov txheej txheem nitriding qhov twg ob qho tib si nitrogen thiab carbon diffuse rau hauv qhov chaw ntawm qhov. Cov txiaj ntsig ntawm cov txheej txheem suav nrog lub peev xwm los ua kom cov khoom tawv ntawm qhov kub qis uas txo qis kev cuam tshuam. Nws kuj tseem pheej yig dua piv rau carburizing thiab lwm cov txheej txheem hardening.

Cov txiaj ntsig ntawm Nitriding thiab Nitrocarburizing suav nrog kev txhim kho lub zog thiab kev hnav zoo dua thiab kev tiv thaiv corrosion

Nitriding thiab nitrocarburizing yog siv rau cov iav, ntsia hlau, lub caij nplooj ntoos hlav, crankshafts thiab camshafts, thiab lwm yam.
