AbolishedTest methods for anodic oxidation coatings of aluminium and aluminium alloys - Part 5：Assessment of resistance of anodic oxidation coatings to cracking by deformation
铝及铝合金阳极氧化膜检测方法 第5部分：用变形法评定阳极氧化膜的抗破裂性
Application Summary AI generated
This standard specifies a test method for evaluating the cracking resistance of anodic oxidation coatings on aluminium and aluminium alloys when subjected to deformation. It is applied in manufacturing and quality control settings, particularly for components like architectural profiles, automotive trim, and electronic enclosures that undergo bending or forming during fabrication or use. The test helps ensure coating durability by simulating real-world stresses that could lead to surface cracking and subsequent corrosion.
