ʻO ka inoa ʻo Nickel:paʻa kemika kiʻekiʻe a me ke kūpaʻa corrosion maikaʻi i nā media he nui. ʻO kona kūlana electrode maʻamau ʻo -0.25V, ʻoi aku ka maikaʻi ma mua o ka hao a me ka maikaʻi ʻole ma mua o ka copper.Nickel hōʻike i ke kūpaʻa corrosion maikaʻi i ka ʻole o ka oxygen dissolved i nā waiwai non-oxidized dilute (eg, HCU, H2SO4), ʻoi aku i nā hopena kūlohelohe a me ka alkaline. . ʻO kēia no ka mea hiki i ka nickel ke passivate, e hana ana i kahi kiʻiʻoniʻoni pale nui ma luna o ka ʻili, ka mea e pale ai i ka nickel mai ka oxidation hou.
Noi:
Hiki ke hoʻohana ʻia e hana i ka mea hoʻomehana uila i nā mea haʻahaʻa haʻahaʻa, e like me ka thermal overload relay, haʻahaʻa-voltage kaapuni breaker, a pēlā aku. nā ʻāpana hoʻoluʻu o nā mea kanu wela, nā mea hoʻomehana wai hānai kiʻekiʻe, a me nā paipu wai kai ma nā moku.
