Kudzima kwegirazi ndiko kupisa chigadzirwa chegirazi kune tembiricha yekuchinja T, pamusoro pe50 ~ 60 C, uye nekukurumidza uye zvakafanana nekuitonhodza mumhepo inotonhorera (kudzima svikiro) (senge air-yakatonhorera quenching, liquid-yakatonhorera quenching, etc.) The layer uye pamusoro pedenga rinogadzira yakakura tembiricha gradient, uye kuzorora nekuda kwekushushikana kwegirazi, uye mhedzisiro yekushushikana kwegirazi. hapana stress inogadzirwa. Iko simba chairo regirazi rakaderera zvakanyanya pane iyo theoretical simba. Zvinoenderana neyakaputsika meshini, girazi rinogona kusimbiswa nekugadzira iyo compressive stress layer pane girazi repamusoro (inozivikanwawo sekuti tempering yemuviri), inova mugumisiro wemagetsi ekuita basa guru.
Mushure mekutonhora, tembiricha gradient inocheneswa zvishoma nezvishoma, uye iyo yakasununguka kushushikana inoshandurwa kuita iri nani kushushikana, izvo zvinokonzeresa kugovaniswa kwakafanana compressive stress layer pane girazi pamusoro. Ukuru hwekushushikana kwemukati uku hunoenderana nehupamhi hwechigadzirwa, chiyero chekutonhora uye coefficient yekuwedzera. Naizvozvo, zvinotendwa kuti kana girazi rakatetepa uye girazi rine yakaderera yekuwedzera coefficient zvakanyanya kuoma kudzima zvigadzirwa zvegirazi zvakadzimwa, maitiro ekugadzira anoita basa guru; , ndiyo mechanical factor inoita basa guru. Kana mhepo inoshandiswa semudziyo wekudzima, inonzi air-cooled quenching; kana zvinwiwa zvakaita segirisi, silicon sleeve, parafini, resin, tara, nezvimwe zvichishandiswa senge svikiro rekudzima, inonzi liquid-cooled quenching. Mukuwedzera, munyu wakadai se nitrate, chromates, sulfates, nezvimwewo zvinoshandiswa se quenching media. Simbi yekudzima svikiro isimbi hupfu, simbi waya yakapfava bhurasho, nezvimwe.
