适用范围：This International Standard specifies requirements for pro-ducing and testing an undyed anodic coating on aluminium alloys. Normally used on high Zn-Mg-Cu (AA 7xxx series) aluminium alloys, this anodic coating is produced by the chromic acid process using 20 V DC.Sealed anodic coatings are applied to aerospace products to improve resistance to corrosion and as a pretreatment for paint-ing. Unsealed anodic coatings provide a suitable surface for the application of structural adhesives and allow increased dura-bility for paints.
