Yiziphi ukucima imvamisa ephezulu?

Ukucisha uhlobo lokwelapha ukushisa, okuhlanganisa ukucisha okuvamile, ukucisha ishayela kanye nokucisha i-isothermal.

Ngokuvamile, ukucisha kwenza i-workpiece ibe ne-microstructure ethile ukuze kuqinisekiswe ukuthi ingxenye ethile ihlangabezana nezakhiwo ezidingekayo zomshini ngemva kokushisa. Ingakwazi ukuthuthukisa ubulukhuni namandla; ukwandisa ukumelana nokugqoka.

I-Pulse quenching ukushisa i-workpiece ngesikhathi esifushane kakhulu (esifana nesekhondi elingu-1/1000) ngosizo lwamandla aphezulu we-pulse, futhi ipholise ngokushesha okukhulu, engathola okusanhlamvu okuhle kakhulu nobulukhuni obuphezulu, akukho deformation, ayikho ifilimu ye-oxide, I-Wear-resistant futhi imelana nokugqwala. Akukho ukuthambisa okudingekayo ngemuva kokucisha.

I-Austempering iwukushisa i-workpiece ekushiseni okucishayo, bese uyibeka endaweni yokugeza kasawoti efudumele eyenza isakhiwo esithile siguqule isikhathi esithile ukuze sithole i-bainite nezinye izakhiwo, ukuze sibe namandla aphezulu kanye nokuqina. Ukucindezelwa kokucisha kuncane, okungavimbela i-denaturation nokuqhekeka. Ifanele izingxenye ezinosayizi omncane nezikhudlwana.
