Vacuum carburizing ng'anjo

Horizontal double chambers carbonitriding ndi ng'anjo yozimitsa mafuta
Carbonitriding ndi ukadaulo wosintha zitsulo pamwamba, womwe umagwiritsidwa ntchito popititsa patsogolo kuuma kwa zitsulo ndikuchepetsa kuvala.
Pochita izi, kusiyana pakati pa maatomu a carbon ndi nayitrogeni kumafalikira muzitsulo, kupanga chotchinga chotsetsereka, chomwe chimawonjezera kuuma ndi modulus pafupi ndi pamwamba.Carbonitriding nthawi zambiri amagwiritsidwa ntchito pazitsulo zotsika kwambiri za carbon zomwe zimakhala zotsika mtengo komanso zosavuta kuzikonza kuti zikhale zokwera mtengo komanso zovuta kukonza zitsulo.Kuuma kwapamwamba kwa magawo a Carbonitriding kumayambira 55 mpaka 62 HRC.

Vacuum carburizing ng'anjo yokhala ndi zoyeserera ndi zowongolera ndi njira yozimitsa
Vacuum carburizing ndi kutentha chogwirira ntchito mu vacuum.Ikafika kutentha pamwamba pa malo ovuta kwambiri, imakhala kwakanthawi, imatulutsa filimu ya oxide, kenako ndikudutsa mu gasi woyeretsedwa wa carburizing kuti asungunuke ndi kufalitsa.Kutentha kwa carburizing kwa vacuum carburizing ndikokwera, mpaka 1030 ℃, ndipo kuthamanga kwa carburizing ndikothamanga.Ntchito yapamtunda ya magawo opangidwa ndi carburized imapangidwa bwino ndi degassing ndi deoxidizing.Kuthamanga kotsatira ndikokwera kwambiri.Carburizing ndi kufalikira kumachitika mobwerezabwereza komanso mosinthana mpaka kukhazikika komanso kuya kwapamwamba komwe kumafunikira.
Kuzama kwa vacuum carburizing ndi kuyika pamwamba kumatha kuwongoleredwa;Ikhoza kusintha zitsulo zazitsulo zomwe zili pamwamba pazitsulo zazitsulo, ndipo kuya kwake kwa carburizing kumakhala kozama kuposa kuya kwenikweni kwa carburizing kwa njira zina.
