Ukwelashwa kokushisa kusetshenziselwa ukuguqula impahla ebonakalayo yeamaketanga ensimbi ayindilinga, ngokuvamile ukukhulisa amandla kanye nezici zokugqoka zeketango elizungezayo lokuhambisa isixhumanisi ngenkathi kugcinwa ukuqina nokuqina okwanele kohlelo lokusebenza.Ukwelashwa kokushisa kuhilela ukusetshenziswa kokushisa, ukupholisa okusheshayo (ukucisha), futhi ngezinye izikhathi ngisho nokupholisa izingxenye emazingeni okushisa aphezulu ukuze uthole umphumela oyifunayo.
Zonke izinsimbi ziqukethe uhlobo oluthile lwe-microstructure.Ama-molecule ashintsha indawo lapho kushisa.Lapho insimbi icinywa, ama-molecule ahlala ku-microstructure entsha, namazinga okuqina akhulayo kanye nokulindela kwamandla nokumelana nokugqoka kwengxenye.Izingxenye zeketango ziphathwa ngokushisa ngokuhlukana ngaphambi kokuhlanganiswa, okusiza ukusetha impahla ehlosiwe yengxenye ngayinye ibe sesimweni esifanele.Kunezindlela eziningi ezahlukene zokwelapha ukushisa ezingasetshenziswa ukulungisa amazinga obulukhuni nokujula.Izindlela ezintathu ezivame kakhulu zokwelapha ukushisa kwezingxenye zamaketango yilezi:
Ngokuqiniswa
Ngokuqinisa kuyinqubo yokushisisa, ukucisha kanye nokuthulisa amaketanga ezixhumanisi eziyindilinga.Le nqubo iqinisa futhi iqinise izinto ngokulinganayo kuso sonke isigaba sezixhumanisi zamaketanga, ngokungafani nezinye izindlela eziqinisa ungqimba lwangaphandle kuphela.Umphumela uba insimbi ethambile eqinile futhi enamandla, kodwa isenayo i-ductility eyanele kanye nokuqina.
I-Carburizing - Ukuqina kwecala
I-Carburizing inqubo yokubeka insimbi kukhabhoni ukuze iqine ngenkathi insimbi ifudunyezwa.Ukwengeza ikhabhoni ebusweni bensimbi kushintsha ukwakheka kwamakhemikhali ukuze ikwazi ukusabela ekwelashweni okushisa kuyilapho igcina ubulukhuni bomgogodla obuthambile, obudonsayo.Ikhabhoni imunca kuphela ezindaweni ezidaluliwe zezixhumanisi, futhi ukujula kokungena kwekhabhoni kulingana nesikhathi esichithwe esithandweni, yingakho kubizwa ngokuthi ukuqina kwekesi.Ukuqiniswa kwekesi kuyawakha amandla ezinsimbi eziqinile kunezinye izindlela eziqinisayo, kodwa ukuqina kwekesi elijulile kungathatha isikhathi esiningi futhi kubiza kakhulu.
Ukuqina kokungeniswa
Ngokufanayo nokuqina, kudinga inqubo yokushisa bese kucinywa, kodwa ukusetshenziswa kokushisa kwenziwa ngendlela elawulwayo ngenqubo yokungeniswa (insimu enamandla kazibuthe).Ukuqina kokungeniswa kuvame ukwenziwa njengenqubo yesibili ngaphezu kokuqina.Inqubo yokungenisa yokulawula ikhawulela ukujula nephethini yezinguquko zokuqina.Ukuqina kwe-induction kusetshenziselwa ukwenza lukhuni ingxenye ethile yengxenye, kunengxenye yonke.
Nakuba ukwelashwa kokushisa kuyindlela ephumelelayo nebalulekile yokuthuthukisa ikhwalithi ye-round link chain, ukukhiqiza amaketanga okuthutha asezingeni eliphezulu, ahlala isikhathi eside kudinga ezinye izinqubo eziningi zokukhiqiza ezifana nokugoba nokushisela.
