Zeziphi iifrikhwensi eziphezulu zokucinywa?
Ziziphi ukucima rhoqo?
Ukucima luhlobo lonyango lobushushu, kubandakanywa ukucima ngokubanzi, ukucima i-pulse kunye nokucima i-isothermal.
Ngokuqhelekileyo, ukucima kwenza ukuba i-workpiece ibe ne-microstructure ethile yokuqinisekisa ukuba icandelo elithile lidibana neempawu ezifunekayo zomatshini emva kokufudumala. Unokuphucula ubunzima kunye namandla; ukwandisa ukumelana nokunxiba.
I-Pulse quenching kukutshisa i-workpiece ngexesha elifutshane kakhulu (njenge-1/1000 yesibini) ngoncedo lwamandla aphezulu e-pulse, kwaye ipholile ngokukhawuleza, enokufumana iinkozo ezintle kakhulu kunye nobunzima obuphezulu, akukho deformation, akukho filimu ye-oxide, i-Wear-resistant kunye ne-corrosion-resistant. Akukho ukuthambisa okufunekayo emva kokucima.
I-Austempering kukutshisa i-workpiece kwiqondo lokushisa lokucima, kwaye emva koko uyibeke kwindawo yokuhlamba ityuwa efudumeleyo eyenza isakhiwo esithile siguqule ixesha elithile ukuze sifumane i-bainite kunye nezinye izakhiwo, ukuze ibe namandla aphezulu kunye nokuqina. Uxinzelelo lokucima luncinci, olunokuthintela i-denaturation kunye nokuqhekeka. Ifanelekile kumacandelo amancinci kunye nobukhulu obukhulu.
