Nguzogide corrosion

Nickel-chromium alloys nwere ezigbo nguzogide corrosion, ọkachasị na gburugburu ikuku oxidation dị elu. Nickel na chromium na-etolite ihe nkiri oxide dị ukwuu n'elu alloy, na-egbochi mmeghachi omume oxidation ọzọ. Dịka ọmụmaatụ, na ikuku okpomọkụ dị elu, oyi akwa a nke ihe nkiri oxide nwere ike ichebe ígwè dị n'ime alloy ahụ site na mmebi ọzọ.

Kemịkalụ kwụsie ike

- Nichrome alloy nwere nkwụsi ike kemịkalụ dị elu ma nwee ike ịnọgidesi ike n'ihu ọtụtụ kemịkalụ. Ọ nwere ụfọdụ nnabata na acid, bases na kemịkalụ ndị ọzọ, mana ọ nwekwara ike meghachi omume na acid oxidizing siri ike.

- Ọla kọpa na ụfọdụ oxidants siri ike (dị ka nitric acid) n'okpuru omume nke mmeghachi omume kemịkalụ na-eme ihe ike karị, nhata mmeghachi omume bụ \(3Cu + 8HNO₃ (dilute) = 3Cu (NO₃ + 2NO↑ + 4H₂O \).
