Lapho amandla kagesi edlula, cishe wonke ama-conductor angakwazi ukukhiqiza ukushisa. Kodwa-ke, akuwona wonke ama-conductor afanelekile ukwenza izakhi zokushisa. Inhlanganisela efanele yezimpawu zikagesi, zemishini, namakhemikhali iyadingeka. Okulandelayo yizici ezibalulekile ekwakhiweni kwezinto zokushisa.
Ukungazweli:Ukukhiqiza ukushisa, isici sokushisa kufanele sibe nokumelana okwanele. Kodwa-ke, ukumelana akukwazi ukuphakama ngokwanele ukuba kube isivikelo. Ukumelana kuyalingana nokumelana nokuphindwaphindwa ngobude bomqhubi ohlukaniswe ngendawo ye-cross-sectional ye-conductor. Ukuze uthole i-cross-section enikeziwe, ukuze uthole umqhubi omfushane, kusetshenziswe impahla ene-resisivity ephezulu.
Izici ze-Antioxidant:I-oxidation ingadla izinto zokufudumeza, ngaleyo ndlela inciphise umthamo wazo noma kulimaze ukwakheka kwazo. Lokhu kukhawulela isikhathi sokuphila se-elementi yokushisisa. Kuzinto zokushisa zensimbi, ukwakha ama-alloys ngama-oxide kusiza ukumelana ne-oxidation ngokwenza isendlalelo se-passivation.
I-temperature coefficient of resistance: Ku-conductor amaningi, njengoba izinga lokushisa likhuphuka, ukumelana nakho kuyanda. Lesi simo sinomthelela obaluleke kakhulu ezintweni ezithile kunakwezinye. Ukushisa, ngokuvamile kungcono kakhulu ukusebenzisa inani eliphansi.
Izakhiwo zemishini:Njengoba impahla isondela esigabeni sayo sokuncibilika noma sokuphinda i-crystallization, ijwayele ukuba buthakathaka futhi iguqulwe uma iqhathaniswa nesimo sayo ekamelweni lokushisa. Isici esihle sokushisa singagcina isimo saso ngisho namazinga okushisa aphezulu. Ngakolunye uhlangothi, i-ductility nayo iyimpahla ebalulekile yemishini, ikakhulukazi izakhi zokushisa zensimbi. I-Ductility yenza i-material idonswe ezintanjeni futhi yakheke ngaphandle kokuphazamisa amandla ayo aqinile.
Iphoyinti lokuncibilika:Ngaphezu kwezinga lokushisa elikhuphuka kakhulu le-oxidation, indawo yokuncibilika yezinto nayo ikhawulela izinga lokushisa layo lokusebenza. Indawo encibilikayo yezinto zokushisa zensimbi ingaphezu kuka-1300 ℃.
Ukwenza ngokwezifiso izinto zokushisisa ngogesi nezifudumezi, izinsizakalo zokubonisana ngezixazululo zokuphatha okushisayo:
