<\/p>\nEl electrodeposici\u00f3n (niquelado qu\u00edmico) se realiza mediante reducci\u00f3n autocatal\u00edtica, que es diferente de la galvanoplastia. La galvanoplastia se realiza mediante una corriente externa debida a la diferencia de potencial entre el sustrato y el medio. Esencialmente, hay ninguna diferencia significativa<\/b> en el principio b\u00e1sico de la formaci\u00f3n de pel\u00edculas.<\/p>\n
El chapado qu\u00edmico se utiliza principalmente para la protecci\u00f3n contra la corrosi\u00f3n y el chapado decorativo. Se aplica ampliamente a autom\u00f3viles, bicicletas, relojes, equipos m\u00e9dicos, contadores, instrumentos y ferreter\u00eda<\/b>. Mediante acci\u00f3n qu\u00edmica, se deposita una pel\u00edcula uniforme de n\u00edquel y\/u otros metales sobre la superficie de metal negro o metal no f\u00e9rreo. La pel\u00edcula puede utilizarse para chapado decorativo, pero se emplea principalmente para niquelado, prevenci\u00f3n de la oxidaci\u00f3n, aumento de la resistencia al desgaste, brillo y est\u00e9tica<\/b>. Se utiliza ampliamente en electr\u00f3nica, instrumentos, dispositivos m\u00e9dicos, aparatos de gimnasia, art\u00edculos para el hogar e industrias manufactureras<\/b>. La capa de metalizado qu\u00edmico tiene un grosor uniforme, y mientras la soluci\u00f3n de metalizado pueda penetrar, la disoluci\u00f3n ser\u00e1 completa y uniforme, por lo que puede conseguir la forma ideal. La galvanoplastia no puede cubrir totalmente piezas complejas, pero puede aplicarse a piezas de cualquier forma<\/b>. El chapado qu\u00edmico con alto contenido en f\u00f3sforo es amorfo<\/b>, y la superficie de la capa galv\u00e1nica no tiene l\u00edmites cristalinos, mientras que la galvanoplastia es t\u00edpicamente cristalino<\/b>. Dado que la galvanoplastia requiere corriente externa, la velocidad de deposici\u00f3n del n\u00edquel galv\u00e1nico es mucho mayor que la del n\u00edquel qu\u00edmico, pero ser\u00e1 necesario preparar antes el mismo espesor de la capa galv\u00e1nica que el de la capa electrol\u00edtica. La fuerza de adherencia de la capa de niquelado qu\u00edmico suele ser superior a la de la capa galv\u00e1nica<\/b>. La galvanoplastia electrol\u00edtica utiliza sobre todo aditivos alimentarios<\/b>, Por ello, el uso de sales de n\u00edquel simples o hipofosfito y otras sustancias hace que el chapado qu\u00edmico sea m\u00e1s respetuoso con el medio ambiente que la galvanoplastia. El niquelado qu\u00edmico actualmente s\u00f3lo tiene un color, que es el color de una aleaci\u00f3n de n\u00edquel puro en el mercado, mientras que la galvanoplastia puede tener muchos colores<\/b>.<\/p>\n

A1:<\/strong> El n\u00edquel qu\u00edmico proporciona una cobertura mucho m\u00e1s uniforme y puede recubrir formas complejas de manera uniforme porque no depende de un campo el\u00e9ctrico externo.<\/p>\n
A2:<\/strong> La dureza del n\u00edquel qu\u00edmico es normalmente mayor (500-600 VHN) que la de muchas capas galv\u00e1nicas (150-400 VHN). Tras el tratamiento t\u00e9rmico, la dureza del n\u00edquel qu\u00edmico puede aumentar a\u00fan m\u00e1s (900-1000 VHN).<\/p>\n
A3:<\/strong> El n\u00edquel qu\u00edmico suele ofrecer una mayor resistencia a la corrosi\u00f3n porque los dep\u00f3sitos de n\u00edquel qu\u00edmico con alto contenido en f\u00f3sforo casi no tienen poros, mientras que los revestimientos galv\u00e1nicos suelen contener poros que reducen la resistencia a la corrosi\u00f3n.<\/p>\n
A4:<\/strong> S\u00ed. El n\u00edquel electrodepositado (alto contenido en Ni) tiene una resistividad el\u00e9ctrica mucho menor (~7 \u03a9-cm en la tabla) que el n\u00edquel qu\u00edmico (60-100 \u03a9-cm), pero el n\u00edquel qu\u00edmico suele ofrecer mejor resistencia a la corrosi\u00f3n y comportamiento frente al desgaste debido a su composici\u00f3n y microestructura.<\/p>","protected":false},"excerpt":{"rendered":"
