Surface Scoring Tool

The scratch tester uses a mechanical stylus to move at a constant speed across the coating surface to create a linear scratch, which is used to evaluate the adhesion of the coating. During operation, a fixed pressure is applied, and the peeling condition of the coating at the scratch edges is observed to determine the bonding strength. It is applied in quality control in the coatings and ink industries, and is used in conjunction with microscopy to analyze coating failure modes.
Selection
When selecting, consider matching the hardness of the substrate to the stylus material. For metal substrates, use a tungsten carbide tip. The testing standard determines the scratch length and speed, with ASTM D6677 requiring a single-pass scratch. The pressure range should cover the thickness of the coating being tested, with 0-20N suitable for conventional coatings. For environmental adaptability, pay attention to corrosion-resistant design, such as choosing a stainless steel body for humid environments.
