Ho tima ke mokhoa oa bohlokoa oa phekolo ea mocheso oa tšepe, o fetolang thepa ea 'mele le ea mechine ea thepa ka ho pholile ka potlako. Nakong ea ts'ebetso ea ho tima, sesebelisoa se kena ka mekhahlelo e kang ho futhumatsa mocheso o phahameng, ho kenya letsoho le ho pholile ka potlako. Ha workpiece e pholile ka potlako ho tloha mocheso o phahameng, ka lebaka la ho fokotsa phetoho ea mohato o tiileng, microstructure ea workpiece e fetoha, ho etsa mehaho e mecha ea lijo-thollo le ho ajoa ha khatello ka hare.
Ka mor'a ho tima, mosebetsi oa ho sebetsa hangata o boemong bo phahameng ba mocheso 'me ha o e-s'o pholile ka ho feletseng mocheso oa kamore. Nakong ena, ka lebaka la phapang e khōlō ea mocheso pakeng tsa holim'a sebaka sa mosebetsi le tikoloho, mosebetsi o tla tsoela pele ho fetisetsa mocheso ho tloha holimo ho ea ka hare. Ts'ebetso ena ea phetisetso ea mocheso e ka lebisa ho li-gradients tsa mocheso oa lehae ka har'a sesebelisoa, ho bolelang hore mocheso o maemong a fapaneng ka har'a workpiece ha o tšoane.
Ka lebaka la khatello e setseng le liphetoho tsa moralo tse hlahisoang nakong ea ts'ebetso ea ho tima, matla le ho thatafala ha mosebetsi oa matsoho li tla ntlafatsoa haholo. Leha ho le joalo, liphetoho tsena li ka boela tsa eketsa brittleness ea workpiece 'me li ka baka mefokolo e meng ea ka hare e kang mapetsong kapa deformation. Ka hona, hoa hlokahala ho etsa phekolo ea tempering holim'a workpiece ho felisa khatello ea kelello e setseng le ho finyella ts'ebetso e hlokahalang.
Tempering ke mokhoa oa ho futhumatsa workpiece ho mocheso o itseng ebe o o pholile, ka sepheo sa ho ntlafatsa microstructure le thepa e hlahisoang ka mor'a ho tima. Thempereichara ka kakaretso e tlase ho feta mocheso o timang, 'me mocheso o loketseng oa mocheso o ka khethoa ho latela litšoaneleho le litlhoko tsa thepa. Ka tloaelo, ha mocheso oa mocheso o phahame, ho theola boima le matla a mosebetsi oa matsoho, ha boima le polasetiki li ntse li eketseha.
Leha ho le joalo, haeba workpiece e e-s'o cooled ho mogote oa kamore, ke hore, e ntse e le mocheso o phahameng, phekolo ea tempering ha e khonehe. Lebaka ke hobane ho futhumatsa ho hloka ho futhumatsa mochini oa mosebetsi ho mocheso o itseng le ho o tšoara ka nako e itseng ho finyella phello e lakatsehang. Haeba workpiece e se e ntse e le mocheso o phahameng, mokhoa oa ho futhumatsa le oa ho pata o ke ke oa khoneha, e leng se tla etsa hore phello ea mocheso e se ke ea finyella litebello.
Ka hona, pele u etsa phekolo ea mocheso, hoa hlokahala ho etsa bonnete ba hore workpiece e pholile ka ho feletseng mocheso oa kamore kapa haufi le mocheso oa kamore. Ke ka tsela ena feela ho ka etsoang phekolo e sebetsang ea tempering ho lokisa tshebetso ea workpiece le ho felisa mefokolo le khatello ea kelello e hlahisoang nakong ea ts'ebetso ea ho tima.
Ka bokhutšoanyane, haeba workpiece e tingoeng e sa pholile mocheso oa kamore, e ke ke ea khona ho fumana phekolo ea mocheso. Ho futhumatsa ho hloka ho futhumatsa mochini oa mosebetsi ho mocheso o itseng le ho o boloka ka nako e itseng, 'me haeba workpiece e se e ntse e le mocheso o phahameng, mokhoa oa ho futhumatsa o ke ke oa sebelisoa ka katleho. Ka hona, ke habohlokoa haholo ho etsa bonnete ba hore workpiece e pholile ka ho feletseng ho mocheso oa kamore pele o chesa nakong ea ts'ebetso ea mocheso oa mocheso ho etsa bonnete ba hore workpiece e ka finyella ts'ebetso e hlokahalang le boleng.
