Carburizing da Nitriding

Menene Carburizing & Nitriding

Injin tsabtace iska mai amfani da Acetylene (AvaC)

Tsarin yin amfani da injin cire hayaki na AvaC wata fasaha ce da ke amfani da acetylene don kawar da matsalar samar da hayaki da kwal da aka sani yana faruwa daga propane, yayin da yake ƙara ƙarfin yin amfani da hayaki ko da a makafi ko ta cikin ramuka.

Ɗaya daga cikin muhimman fa'idodin tsarin AvaC shine yawan samar da carbon, wanda ke tabbatar da cewa yana da kama da carburizing ko da ga yanayin ƙasa mai rikitarwa da kuma yawan kaya mai yawa. Tsarin AvaC ya haɗa da allurar acetylene (boost) da iskar gas mai tsaka tsaki, kamar nitrogen, don yaɗuwa. A lokacin allurar boost, acetylene zai rabu ne kawai idan ya taɓa saman ƙarfe wanda ke ba da damar yin carburizing iri ɗaya.

Mafi kyawun fa'ida ga AvaC za a iya samu lokacin da aka kimanta nau'ikan iskar hydrocarbon daban-daban don rage matsin lamba na carbonization saboda ƙarfin shigarsu cikin ƙananan ramuka masu tsayi, masu makafi. Yin amfani da acetylene a cikin injin tsabtace iska yana haifar da cikakken tasirin carburizing a tsawon tsawon ramin saboda acetylene yana da ikon carburizing daban-daban fiye da na propane ko ethylene.

Fa'idodin tsarin AvaC:

Ci gaba da ƙarfin aiki mai girma

Tabbatar da maimaitawa ta tsari

Mafi kyawun shigar da iskar gas ta acetylene

Tsarin zamani mai buɗewa, mai sauƙin gyarawa

Ƙara yawan canja wurin carbon

Rage lokacin aiwatarwa

Inganta tsarin microstructure, ƙara juriya ga damuwa, da kuma ingancin saman sassa masu kyau

Fadada tattalin arziki don ƙara ƙarfin aiki

Daban-daban ikon kashewa ta amfani da helium, nitrogen, gaurayen iskar gas, ko mai

Fa'idodi akan tanderun yanayi:

Ingantacciyar yanayin aiki tare da ƙirar bango mai sanyi, wanda ke ba da ƙarancin zafin harsashi

Babu buƙatar murfin shaye-shaye masu tsada ko tarin abubuwa

Saurin farawa da rufewa

Ba a buƙatar injinan samar da iskar gas na endothermic

Tanderun kashe gas suna buƙatar ƙarancin sarari a ƙasa kuma babu bayan wankewa don cire man kashe wuta

Ba a buƙatar ramuka ko buƙatun tushe na musamman ba

Carbonitriding

Carbonitriding tsari ne na taurarewa kamar na carburizing, tare da ƙara nitrogen, wanda ake amfani da shi don ƙara juriya ga lalacewa da taurin saman. Idan aka kwatanta da carburizing, yaduwar carbon da nitrogen yana ƙara taurarewar carbon da ƙarfe marasa ƙarfe.

Aikace-aikace na yau da kullun sun haɗa da:giya da shaftspistonsmasu juyawa da bearingslevers a cikin tsarin hydraulic, pneumatic da na injiniya.

Tsarin carbonitriding mai ƙarancin matsin lamba (AvaC-N) yana amfani da acetylene da ammonia. Kamar carburizing, ɓangaren da aka samu yana da akwati mai tauri, mai jure lalacewa. Duk da haka, ba kamar AvaC carburizing ba, zurfin akwatin nitrogen da carbon da aka samu yana tsakanin 0.003" da 0.030". Tunda nitrogen yana ƙara taurarewar ƙarfe, wannan tsari yana samar da sassa tare da ƙarin tauri a cikin zurfin akwatin da aka nuna. Tunda ana yin carbonitriding a ɗan ƙaramin yanayin zafi fiye da carburizing, yana kuma rage karkacewa daga kashewa.

Nitriding da Nitrocarizing

Nitriding tsari ne na taurarewa wanda ke watsa nitrogen zuwa saman ƙarfe, wanda galibi ana amfani da shi a kan ƙarfe mai ƙarancin carbon, ƙarfe mai ƙarancin carbon, aluminum da molybdenum.

Nitrocarburizing wani nau'in tsari ne mai sauƙi na nitriding inda nitrogen da carbon ke yaɗuwa a saman ɓangaren. Fa'idodin tsarin sun haɗa da ikon taurare kayan a yanayin zafi mai ƙarancin zafi wanda ke rage karkacewa. Hakanan yawanci yana da ƙarancin farashi idan aka kwatanta da carburizing da sauran hanyoyin taurarewa.

Fa'idodin Nitriding da Nitrocarburizing sun haɗa da ingantaccen ƙarfi da ingantaccen juriya ga lalacewa da tsatsa

Ana amfani da nitriding da nitrocarburizing don gears, sukurori, maɓuɓɓugan ruwa, crankshafts da camshafts, da sauransu.

An ba da shawarar murhu don yin amfani da carbon da nitriding.
