Tempering ke mokhoa oa ho phekola mocheso oo mocheso o timangmotsoakolihlahisoa tsa tšepe kapa likarolo ho mocheso o itseng, o li tšoara ka nako e itseng, ebe o li pholisa ka tsela e itseng.Tempering ke opereishene e etsoang hang ka mor'a ho tima, 'me hangata ke workpiece e etsoang kalafo ea mocheso.Mokhoa oa ho qetela, kahoo ts'ebetso e kopantsoeng ea ho tima le ho futhumatsa e bitsoa phekolo ea ho qetela.
2. Sepheo se seholo sa ho tima le ho futhumatsa ke:
1) Fokotsa khatello ea kelello ka hare le brittleness.Likarolo tse tingoeng li na le khatello e matla le brittleness.Haeba li sa halefa ka nako, hangata li tla holofala kapa li petsole.
2) Fetola thepa ea mochini ea workpiece.Ka mor'a ho tima, workpiece e na le boima bo phahameng le brittleness.E le ho fihlela litlhoko tse fapaneng tsa ts'ebetso ea li-workpieces tse fapaneng, ho thatafala, matla, polasetiki le ho thatafala ho ka fetoloa ka ho futhumatsa.
3) Boholo bo tsitsitseng ba workpiece.Ho futhumatsa ho ka tsitsisa sebopeho sa metallographic ho netefatsa hore ha se sa tla hlola se holofala nakong ea ts'ebeliso e latelang.
4) Ntlafatsa ts'ebetso ea ho itšeha ea litšepe tse itseng tsa alloy.
Mokhoa oa ho tima le ho futhumatsa o phetha karolo e kholo ho ntlafatsa boleng bacarbide e entsoeng ka samente.Tsohle tsa hajoaleliforomo tse batang tsa tungsten carbidee tla tingoa le ho halefa ka mor'a ho sintering.
