Galvanized mpempe akwụkwọ na igwe anaghị agba nchara
Mpempe akwụkwọ galvanized bụ iji zere mmebi nke elu nke nnukwu efere ígwè ma mee ka ndụ ọrụ ya dịkwuo elu.
A na-ekpuchi elu nke nnukwu efere ígwè ahụ na akwa zinc dara.
Ụdị galvanized oyi akpọrepu ígwè mpempe akwụkwọ a na-akpọ galvanized mpempe akwụkwọ.
A na-ejikarị ngwaahịa eriri galvanized na-ekpo ọkụ na-ekpo ọkụ na ụlọ ọrụ mmepụta ihe, dị ka ihe owuwu injinịa, ụlọ ọrụ ọkụ, trolleys, ọrụ ugbo, ịzụ anụmanụ na ịkụ azụ, na ọrụ azụmahịa.
N'ime ha, ụlọ ọrụ mmepụta ihe na-adabara maka mmepụta nke ngwaahịa mmepụta ihe na-eguzogide corrosion na ụlọ elu ígwè na-acha agba na ihe mkpuchi ụlọ nke ụlọ mmepụta ihe;
ụlọ ọrụ metallurgical na-eji ya emepụta ngwa ụlọ, igwe anwụrụ ọkụ obodo, akụrụngwa kichin, wdg.

Ihe mgbochi corrosion.
Ọrụ ugbo, ịzụ anụmanụ na ịkụ azụ na-abụkarị maka nchekwa nri na njem njem,nri anụ na ihe oriri nju oyi na-emepụta na nhazi akụrụngwa, wdg.A na-ejikarị ọrụ azụmaahịa maka inye ihe, nchekwa na nkwakọ ngwaahịa.
Igwe anaghị agba nchara galvanized mpempe akwụkwọ na-ezo aka nchara nke na-eguzogide ihe ndị na-emebi adịghị ike dị ka gas, uzuoku,mmiri na ihe ndị na-emebi emebi dị ka acid, alkalis na salts.
A makwaara dị ka igwe anaghị agba nchara na ígwè na-eguzogide acid.
N'ime ngwa ụfọdụ, ígwè na-eguzogide ihe ndị na-emebi emebi na-esikarị ike na-akpọ igwe anaghị agba nchara.ebe a na-akpọ ígwè na-eguzogide ihe na-eme ka ihe mgbaze na-eguzogide acid.
Dị ka usoro ya si dị, efere igwe anaghị agba nchara na-ekewakarị n'ime ígwè austenitic, ígwè ferritic,ferritic ígwè, ferritic metallographic Ọdịdị (duplex) igwe anaghị agba nchara efere na mmezi ike igwe anaghị agba nchara efere.
Na mgbakwunye, ọ nwere ike kewaa n'ime chromium igwe anaghị agba nchara, chromium-nickel igwe anaghị agba nchara na chromium manganese nitrogen igwe anaghị agba nchara efere.
Ihe kpatara ya
Nguzogide corrosion nke galvanized igwe anaghị agba nchara na-ebelata site na mmụba nke ọdịnaya carbon.
Ya mere, ọdịnaya carbon nke ọtụtụ efere igwe anaghị agba nchara dị ala, ọ bụghị karịa 1.2%,na Wc (ọdịnaya carbon) nke ụfọdụ nchara erughị 0.03% (dịka ọmụmaatụ, 00Cr12).
Isi ihe aluminom alloy dị na efere igwe anaghị agba nchara bụ Cr (chromium).
Naanị mgbe ọdịnaya mmiri nke Cr karịrị otu uru, ígwè ahụ nwere nguzogide corrosion.
Ya mere, mkpokọta Cr (chromium) mmiri nke igwe anaghị agba nchara bụ opekata mpe 10.5%.
Efere igwe anaghị agba nchara nwekwara ihe ndị dị ka Ni, Ti, Mn, N, Nb, Mo na Si.
Mpempe igwe anaghị agba nchara galvanized adịghị mfe ime ka corrosion, crevice corrosion, nchara, ma ọ bụ mmebi.
N'ime ihe ndị mejupụtara ọla maka iji injinịa, efere igwe anaghị agba nchara bụkwa otu n'ime akụrụngwa nwere ike mkpakọ kacha elu.
Dị ka igwe anaghị agba nchara efere nwere magburu onwe corrosion eguzogide.
Ọ nwere ike ime ka ndị otu ihe nhazi ahụ nọgide na-enwe nkwekọ nke nhazi ihe owuwu ụlọ.
Efere igwe anaghị agba nchara nwere chromium nwekwara mmetụta siri ike na ductility dị elu,nke dị mma maka mmepụta, nhazi na ịmepụta akụkụ, na mkpa nke ndị na-emepụta ihe na ndị na-emepụta ihe n'ozuzu nwere ike ịtụle.
