Tlhaloso ea Tlhahiso
● Ho monya ka tšohanyetso.Ho monyeha ha tšepe ea ductile ho feta ho ts'oaroa ha tšepe e bohlooho.Ha sekhahla sa spheroidization se phahame, ho monyeha ho honyane hoa fokotseha.Ha mocheso o ntse o phahama, ho monya ha tšepe e bohlooho hoa fokotseha, empa phello ea tšepe ea ductile e nyane.
● ho itšeha tshebetso.Aine ea ductile e na le graphite e ngata, e phethang karolo ea ho seha mafura.Ka hona, khanyetso ea ho itšeha ea tšepe ea ductile e tlase ho feta ea tšepe, 'me lebelo la ho itšeha le phahame.
● Weldability.Litšepe tsa ductile ha li khone ho chesetsoa, li lokisoa feela ka ho cheselletsa.Ha litaba tsa lefats'e tse sa tloaelehang tsa magnesium alloy ka tšepe ea ductile li phahame, ho bonolo ho hlahisa molomo o mosoeu kapa sebopeho sa martensitic ho theha khatello ea kelello le mapetsong sebakeng se haufi le weld.
● Ho hanyetsa mocheso.Graphite e ka har'a tšepe ea ductile e arohana ho tloha ho e 'ngoe, e sitisang ho ata ha oksijene ka mocheso o phahameng ha o bapisoa le tšepe e ntšo.Ka hona, khanyetso ea oxidation le khanyetso ea kholo ea tšepe ea ductile e betere ho feta ea tšepe e bohlooho le tšepe e bonolo.Khanyetso e phahameng ea mocheso oa tšepe ea ferritic ductile e betere ho feta ea tšepe ea pearlitic ductile.Ho eketsa litaba tsa silicon kapa aluminium ho ka ntlafatsa khanyetso ea oxidation le ho hanyetsa mocheso oa tšepe ea ductile.
● Ho hanyetsa ho bola.Tšepe ea ductile le tšepe e bohlooho li na le khanyetso e ntle ea kutu ka tharollo ea alkaline, 'me ho hanyetsa ha tšepe ea ductile ho lintho tse phelang, li-sulfide le litšepe tse qhibilihisitsoeng (sebaka se tlaase sa ho qhibiliha) se tšoana le sa tšepe e bohlooho.
● Ho hanyetsa ho ruruha.Tšepe ea ductile ke ntho e ntle e sa sebetseng le e fokotsang ho roala, 'me ho hanyetsa ha eona ho molemo ho feta ea tšepe e bohlooho, tšepe ea carbon esita le tšepe e tlaase ea alloy e nang le matrix e tšoanang.
● (1) Lubrication le ho apara ho hanyetsa, ho hanyetsa ha tšepe ea ductile ho molemo ho feta ea tšepe e bohlooho.
● (2) Abrasive wear, ductile iron e boetse e na le lisebelisoa tse itseng tlas'a maemo a ho apara abrasive.Leha ho le joalo, ha ho bapisoa le tšepe e tšoeu e entsoeng ka tšepe le tšepe e tlaase ea alloy, ho hanyetsa ha tšepe e tloaelehileng ea ductile ha ho molemo haholo, ke alloy ductile iron kapa alloy Bainite ductile iron e nang le khanyetso e ntle ea ho apara.
Sebaka sa Kopo
E sebelisoa bakeng sa ho tsamaisa mefuta e fapaneng ea metsi (mohlala: metsi a tala, metsi a hloekisitsoeng, metsi a sebelisoang hape, joalo-joalo).
