Kudzimisa uye kudziya kurapwa kunoreva nzira mbiri dzekupisa kupisa kwekudzima uye kudziya kwepamusoro-tembiricha, iyo ine chinangwa chekuona kuti workpiece ine yakanaka yakazara mekinika zvivakwa.Kupisa kwakanyanya kunoreva kupisa pakati pe500-650 ℃.Zvikamu zvakawanda zvakadzimwa uye zvakadzimirwa zvinoshanda pasi pemitoro yakakura ine simba, uye inotakura mhedzisiro yekunetsana, kumanikidzana, kukotama, torsion kana kugera.Dzimwe nzvimbo dzinewo kukweshana, kunoda kumwe kusamira kwekupfeka, zvichingodaro.Muchidimbu, zvikamu zvinoshanda pasi pekunetseka kwakasiyana kwakaumbwa.Idzi mhando dzezvikamu zvinonyanya kuumbwa zvemichina akasiyana-siyana uye michina, senge shafts, matanda ekubatanidza, zvitubu, magiya, nezvimwewo, uye anoshandiswa zvakanyanya mumaindasitiri ekugadzira akadai sematurusi emuchina, mota, uye matirakita.Kunyanya kuzvinhu zvakakura mukugadzira muchina unorema, kudzima uye kupisa kurapwa kunonyanya kushandiswa.Naizvozvo, kudzima uye kupisa kurapwa kunoita basa rakakosha mukupisa kurapwa.Muzvigadzirwa zvemichina, zvinodikanwa zvekuita zvezvinodzimwa uye zvakadzikama zvikamu hazvina kufanana zvachose nekuda kwemamiriro avo akasiyana ekushushikana.Nzvimbo dzakasiyana-siyana dzakadzimwa uye dzakadzimirwa dzinofanirwa kuve neakanakisa akazara mekiniki zvivakwa, zvinoti musanganiswa wakakodzera wesimba repamusoro uye kuoma kwepamusoro, kuve nechokwadi chekushanda kwenguva refu kwakatsetseka kwezvikamu.
Kudzima ndiyo danho rekutanga rekuita, uye tembiricha yekudziya inoenderana nekuumbwa kwesimbi, nepo svikiro rekudzima rinosarudzwa zvichienderana nekuoma kwesimbi uye ukuru hwechikamu chesimbi.Mushure mekudzima, kushushikana kwemukati kwesimbi kwakakwira uye brittle, uye kupisa kunodiwa kubvisa kushushikana, kuwedzera kuoma, uye kugadzirisa simba.Tempering ndiyo inonyanya kukosha maitiro ekugadzirisa maitiro emagetsi emagetsi akadzimwa uye anopisa simbi.Iyo curve yemagetsi emhando yesimbi dzakasiyana-siyana inochinja nekudziya tembiricha, inozivikanwawo seyakapisa curve yesimbi, inogona kushandiswa sehwaro hwekusarudza tembiricha yekupisa.Nokuda kwekupisa kwekupisa kweimwe alloy yakadzimwa uye yakadzikama simbi, kutarisisa kunofanira kubhadharwa kudzivirira kuitika kwechipiri rudzi rwekutsamwa brittleness kuve nechokwadi chekushandiswa kwesimbi.[2]
Kudzimisa uye kudziya kurapwa kunoshandiswa zvakanyanya kune zvimiro zvemukati zvinoda mashandiro akazara, kunyanya ayo anoshanda pasi pemitoro inochinjana, senge mota shafts, magiya, turbine shafts einjini dzendege, compressor discs, nezvimwe. anowanzo kudzimwa uye kudzikamiswa pamberi pekudzima kwepamusoro kuti awane yakanaka uye yunifomu sorbate, iyo inobatsira kune yekumusoro kuomarara layer uye inogona zvakare kuwana yakanaka yakazara ma mechanical properties papakati.Zvikamu zveNitride zvinodzimwa uye kudziya kurapwa pamberi penitriding, izvo zvinogona kuvandudza mashandiro esimbi uye kugadzirira chimiro che nitriding.Kuti uwane kutsetseka kwepamusoro kwechiyereso chekuyeresa usati wadzima, bvisa kushushikana kunokonzerwa nehutsinye machining, kuderedza kudzima deformation, uye kuita kuomarara mushure mekudzima yakakwira uye yunifomu, kudzima uye kupisa kurapwa kunogona kuitwa pamberi peiyo machining.Kune masimbi emidziyo ane network carbides kana coarse zviyo mushure mekugadzira, kudzima uye kupisa kurapwa kunogona kushandiswa kubvisa iyo carbide network uye kunatsa zviyo, nepo spheroid zing iyo carbides kuvandudza machinability uye kugadzirira iyo microstructure yekupedzisira kupisa kurapwa.
