Ele apresentou os fundamentos do m\u00e9todo em uma reuni\u00e3o na Academia Real Francesa. Entretanto, o m\u00e9todo n\u00e3o foi muito utilizado at\u00e9 que outro qu\u00edmico franc\u00eas, Sorel, obteve a patente, em 10 de Maio de 1837, introduzindo a decapagem sulf\u00farica (a 9%) e a fluxagem com cloreto de am\u00f4nio como etapas anteriores e fundamentais do processo. A principal parte do processo patenteado por Sorel \u00e9 ainda atualmente utilizada. Em um ap\u00eandice \u00e0 sua patente, datado de Julho de 1837, Sorel denominou o m\u00e9todo de \u00abgalvaniza\u00e7\u00e3o\u201d, referindo-se \u00e0 cela galv\u00e2nica que \u00e9 criada quando o revestimento de zinco \u00e9 danificado. Como visto anteriormente, o a\u00e7o \u00e9 protegido galvanicamente pelo revestimento de zinco.<\/p>\n<p>O termo foi subsequentemente adotado a outros m\u00e9todos de revestimento do a\u00e7o pelo zinco, e, algumas vezes, \u00e9 utilizado para a deposi\u00e7\u00e3o met\u00e1lica eletrol\u00edtica em geral. Para evitar confus\u00e3o, a imers\u00e3o do a\u00e7o em zinco l\u00edquido deve ser referida como galvaniza\u00e7\u00e3o a quente.<\/p>\n<p>Uma patente inglesa para um processo similar foi depositada em 1837. Em 1850, a ind\u00fastria de galvaniza\u00e7\u00e3o inglesa j\u00e1 utilizava 10.000 ton de zinco por ano na prote\u00e7\u00e3o do a\u00e7o.<\/p>\n<p>A galvaniza\u00e7\u00e3o pode ser encontrada em quase que todo tipo de aplica\u00e7\u00e3o e ind\u00fastria onde o a\u00e7o \u00e9 empregado. As ind\u00fastrias de utilidades dom\u00e9sticas, processos qu\u00edmicos, papel e celulose, constru\u00e7\u00e3o civil, transporte, para numerar algumas poucas, tem feito grande uso, hist\u00f3rico, da galvaniza\u00e7\u00e3o, no controle da corros\u00e3o. Por mais de 140 anos, a galvaniza\u00e7\u00e3o a quente tem sido um sucesso comercial como m\u00e9todo de prote\u00e7\u00e3o frente \u00e0 corros\u00e3o de uma grande variedade de aplica\u00e7\u00f5es, por todo o mundo.<\/p>\n<p>Em qualquer situa\u00e7\u00e3o onde o zinco \u00e9 corro\u00eddo como revestimento de sacrif\u00edcio para o a\u00e7o, a massa do zinco dispon\u00edvel determinar\u00e1 o desempenho frente \u00e0 corros\u00e3o.[\/vc_column_text][\/vc_column][vc_column width=\u00bb1\/3\u00bb][\/vc_column][\/vc_row][\/vc_section]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[vc_section][vc_row][vc_column width=\u00bb2\/3&#8243;][vc_column_text]La simplicidad del proceso de galvanizaci\u00f3n en caliente es una ventaja sobre otros m\u00e9todos de protecci\u00f3n contra la corrosi\u00f3n.
