金属覆盖层 覆盖层厚度测量 阳极溶解库仑法
Application Summary AI generated
This standard specifies the coulometric method for measuring the thickness of metallic coatings by anodic dissolution. It is applied in manufacturing and quality control contexts to determine the thickness of single or multiple metallic layers on metal substrates, such as nickel, chromium, or copper coatings on steel or plastic parts. The method is commonly used in the automotive, electronics, and hardware industries for verifying coating thickness on components like fasteners, connectors, and decorative trim.
