MICRO SCRATCH | MICRO ADHESION TESTING

Micro Scratch Process:
During Micro Scratch Testing, a conical spherical tip, diamond or WC, is drawn across the coated surface with an increasing load, resulting in various types of failure at specific critical loads. Micro Scratch Adhesion Testing identifies critical loads optically using a built-in video microscope. These critical loads are used to quantify the adhesive and cohesive properties of different film/substrate combinations. In addition, failure points can be determined using frictional force and depth measurements. Depth measurements provide the plastic and elastic portion of the deformation. Constant load scratch testing can be used, in mapping, to check the surface uniformity. True Depth Measurements based on (European Patent No. 0663068)  providing accurate elastic and plastic deformation.
