The ISO 8251 standard specifies a method for measuring the abrasion resistance of anodic oxidation layers of aluminium and aluminium alloys. Anodic oxidation is a commonly used surface preparation technique that can improve the corrosion resistance, Glossiness and abrasion resistance of aluminium and aluminium alloys. The ISO 8251 standard uses the grinding SHALL test method, which can accurately measure the abrasion resistance of anodic oxidation layers. In addition, the ISO 8251 standard also specifies the accuracy and Repeatability requirements to be met by the abrasion resistance testing of anodic oxidation layers, providing an important reference for the production and use of anodic oxidation layers. Obtaining accurate and reliable anodic oxidation abrasion resistance testing data helps to improve the mass and Reliability of aluminum and aluminum alloy products.
