Ceramics have become enabling materials for many new technologies. Understanding the mechanical behavior of these materials at the nanoscale and the ability to design new ceramics with unique compositions and microstructures has enabled their use in a variety of new applications.  The reliability and performance of ceramics are governed by the mechanical properties of the microstructure (grains, particles, pores, phases, interfaces, additive impurities, etc) along with its relative size, shape, and orientation.  Given the diversity and complexity of technical ceramics, enhanced nanoscale characterization techniques are required to effectively engineer new elastic, hardness, fracture toughness, strength, and tribological properties.  

Nanoindentation of Ceramics

Nanoindentation is a fast and accurate means of measuring localized elastic, fracture, and hardness properties of individual microstructural components within a bulk ceramic. Highly precise test placement accuracy combined with sensitive control over the nanoindentation process enables quantitative, high-resolution mechanical property measurements to be achieved along with spatially resolved mechanical property maps. The information achieved through nanomechanical testing accelerates understanding of ceramic systems and provides a foundation for continued development. 

Nanotribology of Ceramics

The use of ceramics for tribological applications requires the ability to understand localized tribological mechanisms and the capability of modifying microstructural constituents to meet desired tribological performance. Hysitron’s instruments utilize a rigid scratch probe to provide a quantitative measurement of the nanoscale to microscale wear and friction properties of ceramics. The ability to conduct tests on individual constituents within the ceramic and create maps of tribological properties over a surface enhances understanding of nano/microscale wear processes and aids in designing and developing new tribological materials.
