⑴ Ukuqedwa komhlaba
Ingaphezulu lensimbi ngokushisa okusheshayo ekushiseni okubucayi okungenhla, kepha ukushisa akubanga nesikhathi sokusakazeka emgogodleni ngaphambi kokuphola okusheshayo, ukuze ungqimba olungaphezulu lungaqedwa ezicubu zeMartensitic, kanti umnyombo ongaphezulu ungavumi Ushintsho lwesigaba, olubona lukhuni lwangempela kanye nomgogodla ongashintshiwe. Ilungele i-carbon yensimbi ephakathi.

Ukwelashwa okushisa kwamakhemikhali:
Kubhekiswa kuma-athomu we-chemic element, ngekhono lokuvikelwa kwamazinga okushisa aphezulu, kungqimba lomsebenzi wesisebenzi, ukushintsha ukwakheka kwamakhemikhali nokwakheka kwesendlalelo sensimbi engaphezulu, ukuze uzuze isendlalelo sensimbi Ngezidingo ezithile zenhlangano kanye nokwenza kwenqubo yokwelashwa okushisa. Ngokwezinhlobo zezinto zokungena ngaphakathi, ukwelashwa kokushisa kwamakhemikhali kungahlukaniswa ngokuzikhandla, i-nitriding, i-cranidation kanye nomthetho wensimbi.
I-Carburshing: I-Carburshing yinqubo ama-athomu e-carbon angena kuwo ungqimba lwensimbi. Futhi ukwenza umsebenzi wensimbi ophansi we-carbon nge-horder ephezulu ye-carbon steel engaphezulu, bese ngemuva kokucima phansi nokushisa okuphansi, ukuze ungqimba olungaphezulu lomsebenzi lube nobulukhuni obuphezulu futhi lugqoke ukumelana, nengxenye ephakathi nendawo yokwenza umsebenzi Ubulukhuni nobunzima beplastiki yensimbi ephansi yekhabhoni.
I-nitriding, noma i-nitriding, yinqubo yile nhlanganisela yensimbi engena kuwo i-nitrogen athomu. Inhloso ukuthuthukisa ubulukhuni futhi ugqoke ukumelana kwesendlalelo esingaphezulu futhi uthuthukise amandla okukhathala nokuphikiswa kokugqwala. Njengamanje, kusetshenziswa indlela ye-nitring yegesi ekukhiqizweni.
I-Carnidation, eyaziwa nangokuthi i-carbonitrididing, ukufakwa ngasikhathi sinye ama-athomu e-carbon kanye ne-nitrogen kube ngensimbi. Kwenza ingaphezulu le-carburshing yensimbi kanye nezimpawu ze-nitring.
Ukungena kwensimbi: kubhekiselwa ekufundeni kwama-athomu wensimbi kungqimba yensimbi engaphezulu. Kwenza ungqimba olungaphezulu lwensimbi yensimbi, ukuze wenze indawo ye-workpiece inensimbi yensimbi, izici zensimbi ezikhethekile, ukumelana nokushisa, ukumelana nogrolion, njll .. Imvamisa esetshenziswa kakhulu ekukhiqizweni kwe I-Alminiting, chrimizing, boromiting, silicon nokunye.
