Mechanical characterization and optimization of coated surfaces

Mechanical characterization and optimization of coated surfaces is meanwhile necessary in almost all technical fields. ASMEC's measurement technique enables the determination of the necessary mechanical parameters.
 
Based on the nanoindentation principle, ASMEC developed its first own instrument – a Universal Nanomechanical Tester (UNAT) – in 2005. This device is extending the capabilities of other commercial nanoindenters by a second measuring head for the measurement of lateral forces and displacements with high resolution. It helps to close an existing gap in the simulation of real tribological conditions in laboratory environment.
 
Another product ASMEC offers is the recently developed UNAT-SEM II, a nanoindentation head, which can be installed in a Scanning Electron Microscope (SEM). The nanoindenter is designed to carry out micromechanical experiments while simultaneously observing sample and tip with highest magnification. It offers the widest measurement range on the market with a maximum displacement of 200 μm and a maximum force of 200 mN. Simultaneously, the force and displacement noise levels are highly competitive in a vibration free environment. Its internal stiffness is so high that conventional hardness tests can be carried out without problems. The standard system is designed for the installation on the stage of a number of different SEMs, but it can also be mounted on the chamber wall. The existing tilting and moving capabilities of the SEM stage can be used.
 
ASMEC Advanced Surface Mechanics GmbH was established in 2003 by Dr. Thomas Chudoba who has been a recognized expert in the field of surface mechanics and nanoindentation for many years. In August 2011, the Zwick Roell Group has acquired the majority of the ASMEC GmbH in Radeberg. The Zwick Roell Group, with its main quarter in Ulm (Germany), is one of the world’s leading suppliers of materials and component testing systems for R&D and quality assurance. The acquisition expands the group's portfolio with regard to the micro and nano ranges of mechanical test equipment.
