The ISO 2819-2017 review of adhesion test methods for metal overlays and chemically deposited layers on metal substrates provides a test method for evaluating the adhesion of Eletroplating and chemically deposited layers on metal substrates. Adhesion is a key indicator to measure the bonding strength of metal overlays to substrates, which directly affects the service life and performance of coatings. The standard details several commonly used adhesion testing methods, including disbonding test, tensile test, etc., and describes their application scope, operation process, and test requirements. Through these methods, the durability and reliability of Eletroplating and chemical deposition layers in actual use can be evaluated to ensure the reliability of metal coatings in industrial applications. This standard provides an important technical basis for the metal surface preparation industry, which helps to improve the quality control and inspection level of metal coating products.
