O revestimento de convers\u00e3o de cromato, mais conhecido como pel\u00edcula qu\u00edmica ou pelo seu nome comercial Alodine, \u00e9 um revestimento qu\u00edmico que passiva e protege o alum\u00ednio da corros\u00e3o. Tamb\u00e9m \u00e9 utilizado como uma camada de base antes da aplica\u00e7\u00e3o de prim\u00e1rio e da pintura de pe\u00e7as. A norma mais comummente especificada em aplica\u00e7\u00f5es de engenharia \u00e9 a MIL-DTL-5541F, que se refere especificamente ao revestimento de ligas de alum\u00ednio.<\/p>

Esta camada protetora \u00e9 muito mais fina do que uma camada de anodiza\u00e7\u00e3o e, embora ambas sejam criadas por imers\u00e3o das pe\u00e7as num banho, o Alodine \u00e9 um revestimento qu\u00edmico simples e o processo n\u00e3o utiliza corrente el\u00e9ctrica.<\/p>

A alodina \u00e9 um processo ligeiramente mais barato do que a anodiza\u00e7\u00e3o, embora seja mais suscet\u00edvel a riscos, desgaste e danos cosm\u00e9ticos. A cor mais comum do revestimento \u00e9 um dourado-esverdeado iridescente, pelo que tamb\u00e9m pode ser utilizado para fins cosm\u00e9ticos. No entanto, esta cor prov\u00e9m do cr\u00f3mio hexavalente, que \u00e9 t\u00f3xico, pelo que, para efeitos de conformidade com a RoHS, existem tamb\u00e9m vers\u00f5es transparentes do revestimento.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
