Sei girazi rinodzimwa?

Kudzimwa kwegirazi ndiko kupisa chigadzirwa chegirazi kune tembiricha yeT, pamusoro pe50 ~ 60 C, uye nekukurumidza uye zvakafanana nekuitonhodza mumhepo inotonhorera (kudzima svikiro) (senge mhepo-yakatonhorera quenching, mvura-yakatonhorera quenching, etc.) The layer and surface layer inoburitsa tembiricha gradient, uye mhedzisiro inokonzeresa yakasununguka nekuda kwe viscous kuyerera kwegirazi, saka tembiricha gradient asi hapana kushushikana mamiriro anogadzirwa.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.
