⑴ Dusha oo la demiyo:
Ma dusha sare ee birta iyada oo loo marayo kuleyl degdeg ah heerkulka muhiimka ah ee kor ku xusan, laakiin kulaylku ma helin wakhti uu ku faafo xudunta ka hor qaboojinta degdega ah, si lakabka dusha sare loo demiyo nudaha martensitic, iyo xudunta aan la marin. isbeddelka wejiga, kaas oo ogaanaya adkaynta dusha sare iyo xudunta aan isbeddelin. Ku habboon birta kaarboon dhexdhexaadka ah.

⑵ Daaweynta kulaylka kiimikada:
Waxaa loola jeedaa atamka curiyaha kiimikada, oo leh awoodda faafinta atomiga heerkulka sare, waxa galay lakabka sare ee workpiece ah, si ay u beddelaan ka kooban kiimikada iyo qaab-dhismeedka lakabka sare ee workpiece ah, si ay u gaaraan lakabka sare ee birta. shuruudaha gaarka ah ee ururka iyo waxqabadka habka daaweynta kulaylka. Sida laga soo xigtay noocyada kala-soocidda walxaha, daaweynta kulaylka kiimikada waxaa loo qaybin karaa carburizing, nitriding, cyanidation iyo sharciga galitaanka birta.
Kaarbuurayn: Kaarbuurayntu waa habka ay atamka kaarboonku u galaan lakabka sare ee birta. Sidoo kale waa in la sameeyo workpiece steel carbon hoose la lakabka sare ee birta carbon sare, ka dibna ka dib demin iyo heerkulka hooseeyo, si lakabka sare ee workpiece leeyahay engegnaanta sare iyo xidho iska caabin ah, iyo qaybta dhexe ee workpiece weli ilaalin adkaanta iyo caagagga birta kaarboonka ee hooseeya.
Nitriding, ama nitriding, waa habka uu lakabka sare ee birta u galo atamka nitrogen. Ujeedada ayaa ah in la hagaajiyo adkaanta iyo xidhashada caabbinta lakabka dusha sare iyo hagaajinta xoogga daalka iyo caabbinta daxalka. Waqtigan xaadirka ah, habka nitriding gaaska ayaa loo isticmaalaa wax soo saarka.
Cyanidation, oo sidoo kale loo yaqaano karbonitriding, waa isku mar la geliyo kaarboon iyo atamka nitrogen ee birta. Waxay ka dhigtaa dusha sare ee carburizing birta iyo sifooyinka nitriding.
Gelitaanka birta: waxa loola jeedaa galitaanka atamka birta ee lakabka sare ee birta. Waa in la sameeyo lakabka dusha sare ee Alloying birta, si ay u sameeyaan dusha workpiece leeyahay qaar ka mid ah birta daawaha, sifooyinka birta gaar ah, sida iska caabin kulaylka, xidho caabbinta, iska caabin oksidation, iska caabin daxalka, iwm .. Caadi ahaan loo isticmaalo wax soo saarka ee aluminium, chromizing, boronizing, silicon iyo wixii la mid ah.
