Las leyes de control de emisiones y protección del medio ambiente, implantadas desde hace unos 30 años en los países industrializados, han logrado una disminución apreciable en los niveles de SO2, uno de los principales contaminantes que intervienen en la corrosión atmosférica del zinc. Sin embargo, otros contaminantes atmosféricos, entre los que se incluyen los óxidos de nitrógeno (NOx), han mantenido un nivel constante o incluso han aumentado ligeramente su concentración, con lo cual su importancia relativa se ha incrementado. Este libro es resultado de la investigación del efecto del NO2 en la corrosión atmosférica del zinc, a partir de datos obtenidos mediante ensayos de laboratorio en los cuales se simularon las condiciones de depósito por vía seca de NO2, solo y en combinación con el SO2, a diferentes temperaturas y humedades relativas, en exposiciones de entre 7 y 21 días de duración, y combinando análisis gravimétricos con técnicas de caracterización de los productos de corrosión formados (microscopía óptica, MEB/EDX, DRX de ángulo rasante y XPS).
