energia<\/a> elétrica e química dos materiais. Em eletrônica e sistemas aviônicos, a manipulação precisa de elétrons — que formam as cargas negativas em íons — é fundamental para a condução elétrica e funcionamento dos circuitos.<\/p>\n\n\n\nOs íons são também essenciais na corrosão de metais, fenômeno relevante na aviação. Corrosão ocorre quando íons de metal reagem com o oxigênio e outros elementos no ambiente, formando óxidos ou outros compostos que deterioram a estrutura do material.<\/p>\n","protected":false},"excerpt":{"rendered":"
