Ukucima kunye nonyango olushushu lubhekisela kwindlela yonyango yokushisa kabini yokucima kunye nobushushu obuphezulu, obujolise ekuqinisekiseni ukuba i-workpiece ineempawu ezilungileyo ezibanzi zoomatshini. Ubushushu obuphezulu bubhekisa kubushushu obuphakathi kwe500-650 ℃. Uninzi lwamalungu acinyiweyo kunye nobushushu asebenza phantsi kwemithwalo emikhulu eguqukayo, kwaye athwala iziphumo zoxinzelelo, uxinzelelo, ukugoba, ukugoba okanye ukucheba. Eminye imiphezulu ikwanazo nokukhuhlana, kufuna ukuxhathisa okuthile, njalo njalo. Ngamafutshane, amalungu asebenza phantsi koxinzelelo olwahlukeneyo oludibeneyo. Ezi ntlobo zamacandelo ubukhulu becala zizinto zolwakhiwo koomatshini kunye neendlela ezahlukeneyo, ezinje ngeeshafti, iinduku zokuqhagamshela, izigxobo, iigiya, njl. Ngokukodwa kumacandelo amakhulu kwimveliso yomatshini onzima, ukucima kunye nonyango lokufudumala lusetyenziswa ngokuqhelekileyo. Ngoko ke, ukucima kunye nonyango lokufudumala ludlala indima ebaluleke kakhulu kunyango lobushushu. Kwiimveliso zoomatshini, iimfuno zokusebenza zamacandelo acinyiweyo kunye nobushushu azifani ngokupheleleyo ngenxa yeemeko zabo ezahlukeneyo zoxinzelelo. Amacandelo ahlukeneyo acinyiweyo kunye nobushushu kufuneka abe neepropathi ezigqibeleleyo zomatshini, ezizezi, indibaniselwano efanelekileyo yamandla aphezulu kunye nokuqina okuphezulu, ukuqinisekisa ukusebenza kakuhle kwexesha elide kwamalungu.
Ukucinywa yinyathelo lokuqala lenkqubo, kwaye ubushushu bokufudumala buxhomekeke ekubunjweni kwentsimbi, ngelixa i-medium quenching ikhethwa ngokusekelwe kubunzima bentsimbi kunye nobukhulu becandelo lentsimbi. Emva kokucima, uxinzelelo lwangaphakathi lwentsimbi luphezulu kwaye luncinci, kwaye ukufudumala kuyimfuneko ukuphelisa uxinzelelo, ukwandisa ukuqina, kunye nokulungelelanisa amandla. I-Tempering yinkqubo ebaluleke kakhulu yokulungelelanisa iimpawu zomatshini zentsimbi ecinyiweyo kunye neyomsindo. Igophe leepropathi zoomatshini zeentsimbi ezahlukeneyo eziguqukayo kunye nobushushu obutshisayo, obukwabizwa ngokuba yigophe eliqukuqelayo lentsimbi, linokusetyenziswa njengesiseko sokukhetha ubushushu bobushushu. Ukushisa okuphezulu kobushushu be-alloy ethile ecinyiweyo kunye neentsimbi ezixubileyo, ingqalelo kufuneka ihlawulwe ekuthinteleni ukwenzeka kohlobo lwesibini lwe-tender brittleness ukuqinisekisa ukusetyenziswa kwentsimbi.

Ukucinywa kunye nonyango olushushu lusetyenziswa ngokubanzi kumacandelo olwakhiwo afuna ukusebenza okugqwesileyo okugqwesileyo, ngakumbi abo basebenza phantsi kwemithwalo etshintshanayo, njengeeshafu zemoto, iigiya, iishafti ze-injini yeenqwelomoya, iidiski zokucinezela, njl njl. zikholisa ukucinywa kwaye zincitshiswe ngaphambi kokucinywa komphezulu ukufumana i-sorbate ecocekileyo nefanayo, enenzuzo kumphezulu. umaleko wokuqina kwaye unokufezekisa iipropathi ezilungileyo ezibanzi zoomatshini kumbindi. Amalungu e-nitride afumana unyango olucinywayo kunye nobushushu ngaphambi kokuba i-nitriding iphucule, inokuphucula ukusebenza kwentsimbi kwaye ilungiselele ulwakhiwo lwe-nitriding. Ukufezekisa ukugudiswa okuphezulu kwesixhobo sokulinganisa ngaphambi kokucima, ukuphelisa uxinzelelo olubangelwa kumatshini olukhuni, ukunciphisa ukucima ukuguqulwa, kwaye wenze ubunzima emva kokucima okuphezulu kunye nokufana, ukucinywa kunye nokunyanzeliswa konyango kunokuqhutyelwa ngaphambi kokulungiswa ngokuchanekileyo. Kwiintsimbi zesixhobo kunye ne-network carbides okanye iinkozo ezirhabaxa emva kokubumba, ukucinywa kunye nonyango olushushu lungasetyenziselwa ukuphelisa inethiwekhi ye-carbide kunye nokucoca iinkozo, ngelixa i-spheroid zing i-carbides ukuphucula ubuchule kunye nokulungisa i-microstructure yonyango lokugqibela lobushushu.
