Nickel Aluminom Bronze

Nickel-aluminom bronze nwere magburu onwe nguzogide nrụgide mgbawa corrosion, ike ọgwụgwụ corrosion, cavitation corrosion, mbuze eguzogide na mmiri ntule organism.E jiri ya tụnyere igwe anaghị agba nchara na mmiri mmiri nwere 3% NaCI, nickel-aluminom bronze alloy nwere ezigbo nguzogide mmebi cavitation.Nrụrụ nke nickel aluminum bronze n'ime mmiri oké osimiri bụ corrosion corrosion na crevice corrosion.Nickel-aluminom bronze na-enwe mmetụta maka ọsọ mmiri nke oke osimiri, ma mgbe ọsọ ya gafere oke ọsọ dị oke egwu, ọnụ ọgụgụ corrosion na-abawanye nke ọma.

Igwe anaghị agba nchara

Nguzogide corrosion nke igwe anaghị agba nchara dịgasị iche na ihe mejupụtara kemịkalụ nke ihe ahụ.Igwe anaghị agba nchara 304 na-eguzogide ọgwụ na-emebi corrosion na mgbawa corrosion na gburugburu mmiri nwere chlorides, enweghịkwa ike iji ya dị ka ihe na-asọba na mmiri mmiri.316L bụ austenitic igwe anaghị agba nchara nwere molybdenum, nke nwere mma iguzogide n'ozuzu corrosion, pitting corrosion na mgbape corrosion.
