The Nanovea Tribometer (TableTop 60 x 39 x 62cm) offers precise and repeatable wear and friction testing using pin-on-disk and linear modes. Designed, at the core, with a high quality motor and a 20bit position encoder, the Tribometer provides access to an unmatched range of rotational speeds from 0.01 to 2000rpm. High resolution means that data can be accurately recorded at specified interval of time or position (>0.006°). The motor has an integrated self-tuning system which ensures speed remains calibrated through time. Full and precise control of the motor ensures that a series of step speeds can be run continuously during the tests.
For wear measurement, weight loss can be measured using a sensitive weight scale before and after the test. Furthermore, an LVDT can be attached to the measuring arm to record depth during the test. This gives the possibility to follow the change of wear rate versus time. Friction force is measured directly with a stiff load cell which offers high resolution with excellent mechanical and thermal stability; unlike other systems that rely only on LVDT for friction measurement. A ball, pin or flat holder is attached to the measuring arm which can be precisely positioned to a resolution of 2.5micron using the standard motorized table. Several testing options are available to closely match real environment conditions. The Tribometer comes standard with an acrylic enclosure and attached valves which brings inert and other gases to achieve a controlled environment. An optional humidifier and dehumidifier module allows precise control of the humidity levels. For high temperature pin on disk, up to 900°C, an oven allows control to better than 1°C. A linear heating plate is used for reciprocating test up to 300°C. Various cups are available for controlled liquid testing. Tests can either be done under full immersion or using the Lubrication system with drop by drop or control spray. A liquid heating module is also available to provide controlled liquid heating up to 150°C.
To precisely measure wear track volume, a full 3D non-contact Optical profiler, integrated on Tribometer platform, is available to quantify wear loss in a fast and convenient method without sample removal. The Tribometer Software uses this information and the test parameters to calculate a precise wear rate for the specific test. The profiler, which has extended capability, can also be used for surface topography measurement including roughness. A Flexible mobile imaging option allows zoom-in ability to record the sample surface for playback review. *For Tribometer specifications see brochure download.
