Project Introduction
The scratch test is one of the commonly used standard methods for testing the bonding strength between the surface film and the base material. Use a material with a hardness greater than the surface film to make a sharp tip to scratch on the surface of the sample or workpiece. Add a load to the scratch head until the film and the substrate are out of contact. At this time, the load is the critical load, and the surface film and the surface film can be calculated. Bonding strength between substrates.
Application range
The scratch test is mainly used to detect and evaluate the anti-shear, scratch, planing, scratch and engraving properties of materials such as anodized materials, rigid organic materials, powder coatings, soft metals, plastics, glass and paint adhesives.
