Coating Adhesion Scratch Tester

The coating adhesion scratch tester uses a diamond indenter to move at a constant speed on the coating surface while applying an increasing load. The critical load value is recorded when the coating begins to peel off, reflecting the bonding strength between the coating and the substrate. It is used to evaluate the quality of surface treatments such as paint and electroplating, ensuring product durability.
Selection
When selecting, consider matching the hardness range of the tested coating with the instrument's load range, as the flatness of the substrate affects testing accuracy. The scratching speed should be adapted to the material properties, and the observation system should have real-time monitoring capabilities. Controlling ambient temperature and humidity can reduce testing errors, and priority should be given to equipment with standard calibration certificates.
