The standard "GB/T 40737-2021 Remanufacturing, Laser Cladding Layer Performance Test Method" specifies various performance test requirements for remanufacturing laser cladding layers, including Film thickness, metallographic structure analysis, tensile, bending, impact test, fracture analysis, hardness, surface defect detection, abrasion resistance and corrosion resistance. The standard describes in detail the basic requirements for sample preparation, test equipment, test conditions, procedures, results and reports. The standard is applicable to the performance evaluation of laser cladding layers for remanufactured mechanical products, and can also refer to the tests used for new products. Several relevant metal material test standards are cited to ensure the standardization of test methods and the reliability of data.
