Micro-scratch test being performed on a material (on black block at centre right). This test is used for thin films or coatings. The stylus applies pressure to the material, which is then studied under a microscope to evaluate the damage. Micro-scratch testing can provide information on the scratch resistance of a material and its ability to adhere to a substrate. Photographed at the National Physical Laboratory, Teddington, UK.
