Microhardness Determination of Coatings on Nanometer scales with PICODENTOR? HM500

Helmut Fischer GmbH Institut für Elektronik und Messtechnik2, Sindelfingen, Germany

With the PICODENTOR® HM500, Helmut Fischer GmbH Institut für Elektronik und Messtechnik has launched a high performance measuring system for determining micro-hardness according to ISO 14577 and ASTM E 2546. This instrument is ideally suited for the determination of the Martens hardness (HM), elastic characteristics and other material parameters of hard coatings, thin DLC coatings and coatings on glass, CDs, hard disks and sensors, as well as of thin paint layers and ion-implanted surfaces.

Measurements can generally be undertaken without complex sample preparation. Thus the PICODENTOR® HM500 is suitable not only for use in laboratory conditions, but also for quick deployment in production monitoring.

With high-precision distance measurements in the picometer range and force control at a level of just a few micronewtons, hardness measurements are possible even for ultra-thin coatings. Featuring a repeatability of <0.5 µm, the high-precision, programmable XY-table allows measurements on even the very smallest of structures. Its compact design and granite base make the PICODENTOR® HM500 dimensionally stable and superbly isolated against vibration. To further minimise environmental influences, the system operates within a closed measuring chamber and uses an active vibration-damping table.

The PICODENTOR® HM500 also has an enhanced optical system for higher resolution of extremely small structures and a motorised z-axis with autofocus. Its easy and intuitive operation is facilitated by the customisable, multi-language software package WIN®-HCU. A wide range of accessories is available, including several hardness reference plates, an integrated atomic force microscope and a variety of sample holders.
