Carburizing & Nitriding

Menene Carburizing & Nitriding

Vacuum Carburizing tare da acetylene (AvaC)

The AvaC vacuum carburizing tsari fasaha ce da ke amfani da acetylene don kusan kawar da matsalar samuwar soot da kwal da aka sani da faruwa daga propane, yayin da ƙara ƙarfin carburizing ko da na makafi ko ta ramuka.

Ɗaya daga cikin mafi mahimmancin fa'idodin tsarin AvaC shine babban wadatar carbon, yana tabbatar da ƙayyadaddun carburizing mai kama da juna har ma da hadaddun geometries da yawa masu yawa.Tsarin AvaC ya ƙunshi madadin allura na acetylene (ƙarfafa) da iskar gas mai tsaka tsaki, kamar nitrogen, don yaduwa.A yayin allura na haɓakawa, acetylene kawai za ta rabu cikin hulɗa da duk wani saman ƙarfe wanda ke ba da izinin carburizing iri ɗaya.

Za a iya samun fa'idar da ta fi dacewa ga AvaC lokacin da aka ƙididdige iskar gas na hydrocarbon daban-daban don ƙarancin ƙarancin ƙarfi don shigarsu cikin ƙananan diamita, dogayen, ramukan makafi.Vacuum carburizing tare da acetylene yana haifar da cikakken tasirin carburizing tare da tsayin daka saboda acetylene yana da ikon ɗaukar carburing gaba ɗaya fiye da na propane ko ethylene.

Fa'idodin tsarin AvaC:

Ci gaba da iyawa mai girma

Tabbatar da maimaita aikin tsari

Mafi kyawun tura gas acetylene

Buɗe, tsarin kulawa mai dacewa

Ƙara yawan canja wurin carbon

Rage lokacin tsari

Inganta microstructure, ƙara ƙarfin juriya, da ingantaccen ingancin sassa

Ƙaddamar tattalin arziki don haɓaka ƙarfin aiki

Iri daban-daban na quenching tare da helium, nitrogen, gauraye gas, ko mai

Fa'idodi akan tanderun yanayi:

Kyakkyawan yanayin aiki tare da ƙirar bangon sanyi, wanda ke ba da ƙananan zafin jiki na harsashi

Ba a buqatar rumfunan shaye-shaye mai tsada ko tari

Saurin farawa da rufewa

Babu endothermic gas janareta da ake bukata

Tanderun kashe iskar gas yana buƙatar ƙasa da sarari kuma babu bayan wankewa don cire mai mai kashewa

Babu ramummuka ko buƙatun tushe na musamman da ake buƙata

Carbonitriding

Carbonitriding wani tsari ne na tauraro mai kama da carburizing, tare da ƙari na nitrogen, ana amfani da shi don haɓaka juriya da taurin saman.Idan aka kwatanta da carburizing, yaɗuwar carbon da nitrogen yana ƙaruwa da ƙarfi na ƙarancin carbon da ƙananan karafa.

Aikace-aikace na yau da kullun sun haɗa da:gears da shaftspistonsrollers da bearingslevers a cikin na'ura mai aiki da karfin ruwa, pneumatic da inji actuated tsarin.

Low matsa lamba carbonitriding (AvaC-N) tsari yana amfani da acetylene da ammonia.Kamar carburizing, abin da ya haifar yana da matsala mai wuya, mai jurewa lalacewa.Koyaya, sabanin AvaC carburizing, sakamakon nitrogen da zurfin yanayin carbon yana tsakanin 0.003 ″ da 0.030″.Tun da nitrogen yana ƙara ƙarfin ƙarfin ƙarfe, wannan tsari yana samar da sassa tare da ƙãra ƙarfi a cikin zurfin yanayin da aka nuna.Tunda ana yin carbonitriding a ƙananan yanayin zafi fiye da carburizing, yana kuma rage murdiya daga quenching.

Nitriding & Nitrocarburizing

Nitriding wani tsari ne na taurare yanayin da ke watsa nitrogen zuwa saman wani ƙarfe, galibi ƙananan carbon, ƙananan karafa.Hakanan ana amfani dashi akan matsakaici da manyan ƙarfe na carbon, titanium, aluminum da molybdenum.

Nitrocarburizing shine bambancin yanayin yanayin nitriding inda duka nitrogen da carbon ke bazuwa cikin saman sashin.Fa'idodin tsarin sun haɗa da ikon taurara kayan a cikin ƙananan yanayin zafi wanda ke rage murdiya.Har ila yau, yawanci ƙananan kuɗi ne idan aka kwatanta da carburizing da sauran matakan hardening yanayi.

Fa'idodin Nitriding da Nitrocarburizing sun haɗa da ingantaccen ƙarfi da mafi kyawun lalacewa da juriya na lalata

Nitriding da nitrocarburizing ana amfani da su don gears, sukurori, maɓuɓɓugan ruwa, crankshafts da camshafts, da sauransu.

Furnace da aka ba da shawarar don carburizing da nitriding.
