GB/T 40338-2021 "Corrosion of metals and alloys, flaking corrosion test of aluminum alloys" stipulates the flaking corrosion test method of aluminum alloys. The standard covers the test principle, sample preparation, equipment, operation process and result evaluation. By simulating the corrosive environment, the flaking corrosion phenomenon of aluminum alloys occurs, and the anti-flaking corrosion performance is scientifically evaluated. It provides a standardized technical basis for mass testing, material selection and process optimization of aluminum alloys to ensure the reliability of aluminum alloy materials in practical applications.
