Lapho wenza umhlobiso wasekhaya, izintambo zethusi kanye nezintambo ze-aluminium akufanele zixhumeke ngokuqondile kanyekanye. Lokhu kungenxa yokuthi kunezinkinga ezithile ekuxhumekeni kukagesi phakathi kwethusi ne-aluminium. Izizathu ezithile zimi ngokulandelayo
Phansi kwa
1. I-Electrochemical Corlosion: I-Copper ne-aluminium ingabhekana nokugqwala kwe-electrochemical emoyeni. Lapho behlangana, ikakhulukazi endaweni enomswakama, i-aluminium isebenza njenge-electrode engemihle
Ukugqwala kwenzeka, futhi ithusi lisebenza njenge-electrode enhle, okwenza ingxenye ehlanganisiwe yocingo lwe-aluminium ukuze ikhulise kancane kancane i-Corpence futhi yandise ukumelana nokuxhumana.
Okwesibili, umehluko ekulweni: Ukumelana kwethusi kuphansi kunalokho kwe-aluminium, okusho ukuthi ucingo lwethusi lunokumelana okuncane nokusebenza okungcono kukagesi ngaphansi kwezimo ezifanayo. Lapho ucingo lwethuli ne-aluminium kuxhumeke ngokuqondile
Lapho uxhuma, ngenxa yokumelana okuhlukile, ukumelana nephuzu lokuxhuma kuzokhula.
Ama-coefficients amathathu, ahlukene wokunwetshwa kwe-thermal: ithusi ne-aluminium banama-coefficients ahlukile wokunwebeka okushisayo, okusho ukuthi bayakhula ngamazinga ahlukene lapho izinga lokushisa lishintsha, futhi lokhu kungaholela ezinkingeni zamaphoyinti okuxhuma
Kukhiqizwa igebe, ngaleyo ndlela kwandise ukumelana nokuxhumana.
