Vacuum isithando somlilo se-carburizing

Amakamelo avundlile akabili i-carbonitriding kanye nesithando somlilo sokucisha uwoyela
I-Carbonitriding ubuchwepheshe bokuguqulwa kwe-metallurgical surface, obusetshenziselwa ukuthuthukisa ubulukhuni bezinsimbi nokunciphisa ukuguga.
Kule nqubo, igebe phakathi kwe-carbon ne-athomu ye-nitrogen lisakazeka ensimbi, lenze umgoqo oshelelayo, okwandisa ubulukhuni kanye ne-modulus eduze kwendawo.I-Carbonitriding ivamise ukusetshenziselwa izinsimbi ezinekhabhoni ephansi ezishibhile futhi kulula ukuzicubungula ukuze zinikeze izakhiwo ezingaphezulu ezibiza kakhulu futhi ezinzima ukucutshungulwa kwamabanga ensimbi.Ukuqina kobuso bezingxenye zeCarbonitriding kusuka ku-55 kuya ku-62 HRC.

Vacuum isithando somlilo se-carburizing esinesistimu yokulingisa nokulawula kanye nohlelo lokucisha
I-vacuum carburizing ukushisa i-workpiece ku-vacuum.Uma ifinyelela izinga lokushisa elingaphezu kwephuzu elibucayi, izohlala isikhathi esithile, i-degass futhi isuse ifilimu ye-oxide, bese idlulela kugesi we-carburizing ohlanziwe we-carburizing kanye nokusabalalisa.Izinga lokushisa le-carburizing le-vacuum carburizing liphezulu, lifinyelela ku-1030 ℃, futhi isivinini se-carburizing siyashesha.Umsebenzi ongaphezulu wezingxenye ze-carburized uthuthukiswa ngokukhipha umoya kanye ne-deoxidizing.Isivinini sokusabalalisa esilandelayo siphezulu kakhulu.I-Carburizing kanye nokusabalalisa kwenziwa ngokuphindaphindiwe futhi ngokushintshana kuze kube yilapho ukugxila nokujula okudingekayo kufinyelelwe.
Ukujula kwe-vacuum carburizing kanye nokugxila kwendawo kungalawulwa;Ingashintsha izici ze-metallurgical zongqimba olungaphezulu lwezingxenye zensimbi, futhi ukujula kwayo okusebenzayo kwe-carburizing kujule kunokujula kwangempela kwe-carburizing kwezinye izindlela.
