Coatings are widely used in various industrial fields for purposes such as protecting underlying layers, manufacturing electronic devices, and enhancing the surface properties of materials. Due to their diverse applications, coatings are extensively researched, but understanding their mechanical properties can sometimes be challenging. Coating failure can occur at the micro/nanometer level due to interactions between the surface and the atmosphere, cohesive failure, or poor adhesion at the interface with the substrate. One method for consistently testing coating failure is the scratch test. By gradually increasing the load, it becomes possible to quantitatively compare cohesive failure of the coating (e.g., cracking) and adhesive failure (e.g., peeling).

basic information
A system that makes it possible to do everything with just one device. Nanovia's nano/micro indenter (mechanical tester) accurately measures the micro to nano mechanical properties of a wide range of materials, from "thin films," "coatings," "ceramics," and "composites" to "polymers" and "biomaterials," through "scratch," "indentation," "abrasion," and "friction tests." All models are equipped with independent load sensors and depth sensors for true feedback load control, achieving unparalleled accuracy and the best reproducibility available on the market.
