TRIBOMETERS MICRO-MACRO TRIBOLOGY TESTING

1 TRIBOMETERS MICRO-MACRO TRIBOLOGY TESTING The Tribometer provides highly accurate and repeatable wear friction testing in rotative and linear modes compliant to ISO and ASTM standards. Designed, at the core, with a high quality motor with a 20bit position encoder, the Tribometer provides access to an unmatched range of rotational speeds from 0.01 to 2000rpm. These speeds can be changed quickly in either a stepwise jump or at a continuous rate. This is specifically useful to obtain Stribeck curves or to study static coefficient behaviors. Data can be accurately recorded at specified interval of time or position (>0.006 ). The motor has also an integrated self-tuning system which ensures that speeds remain calibrated through time. To 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. A large removable oven allows for high temperature rotative testing up to 900 C. Also, tests can either be done in full immersion for the study of wear and/or corrosion. A Lubrication system is also available for drop by drop or continuous spray of liquids. A heating probe is also available to provide controlled liquid heating up to 150 C. To precisely measure wear track volume, a non-contact optical profiler module is used to quantify wear rate in a fast and convenient manner without removing the sample. This gives the unique capability to measure the variation of wear rate during the same test. A mobile imaging option allows recording of the sample surface before and after the test. Because Tribology tests are often of long durations, and require a durable and open testing area, a dedicated Tribometer is preferred to that of a so-called "universal" testing system.the robust high quality design allows Nanovea to offer the longest warranty in the industry.

2 The compact Micro Tribometer is designed for loads from 100mN to 40N. A coated 20mm thick steel plate ensures stability and longevity of the system. A load cell directly attached in-line to the balancing arm offers high sensitivity and accuracy for applications with low level of friction. This load cell is compensated in temperature which ensures accuracy when the high temperature oven is used. The tribocorrosion module is only available on this model. The Micro Tribometer is highly accurate, has the longest warranty in the industry and uses a wide range of environmental conditions options.

4 The rotative wear friction test reproduces the rotational motion found in many real-world tribology mechanisms. A flat, pin or ball tip is loaded onto a test sample with a precisely known weight and at a specific position from the center of rotation. As the sample starts rotating, the tip creates a rotational wear track. Friction coefficient is accurately measured during the test by the deflection of a load cell which is precisely calibrated. Wear rates for the tip and the sample are calculated from the volume of material lost during the test. Depth can be recorded during the test using an accurate LVDT or an optical pen sensor attached to the loading arm. A wide variety of testing are possible including varying radius and speeds during the test.

5 The linear wear friction test reproduces the linear reciprocating motion found in many real-world tribology mechanisms. A flat, pin or ball tip is loaded onto a test sample with a precisely known weight and at a specific position from the center of rotation. As the sample start rotating, the tip creates a linear wear track. Friction coefficient is accurately measured during the test by the deflection of a load cell which is precisely calibrated. Friction forces are recorded for both forward and backward movements of the stroke. Wear rates for the tip and the sample are calculated from the volume of material lost during the test. Depth can be recorded, during the test, using an accurate LVDT or an optical pen sensor attached to the loading arm. A wide variety of testing are possible including varying radius and speed during the test. LINEAR WEAR FRICTION Standards: ASTM G133 ASTM G171 ASTM F732 Properties Analyzed During Linear Wear Friction Test: Friction Coefficient Wear Rates Failure Points Electrical Resistance Lubrication studies Corrosion Studies Friction vs Speed and many others Friction & depth vs cycle/ time using precise fix cycle view with 3D profiler integration Linear Wear Friction Test Software Features: Export Raw Data and Images Real Time Display Automatic Reporting Multi-Language Support Macros with variation of speed Fixed Cycle View Cycle Compare View Automatic Wear Calculation Variable Speed Control during Test and others Tips: (Diamond, WC, Rubber and many other materials) 1, 3, 6 and 10mm ball Custom ball sizes Custom Pins Flat Plate Custom geometries Rotative Linear Wear Depth Sample(s) Holders and Environmental Conditions: Standard Clamp Clip Mounting on Base Plate Other Sample Holders available for varied geometries 350 C Heating Plate Liquid Cup and Liquid Heating-to 150 C Lubrication Drop by Drop and Spay Humidity Control Corrosion Testing Cup Various Gases Same system linear testing provides a critical comparative wear evaluation Wear Loss Measurement Options: LVDT 2D In-situ Optical Pen 3D Optical Profiler Integration Handheld Video Imaging Certain sample size and geometries can be better tested with Linear

6 Digital Mobile Imaging The flexible mobile zoom imaging capture can be moved by hand to conveniently allow zoom-in microscope capability while recording for play back review. This feature is especially useful for later review of surface wear during actual testing. Zoom from 5x to 200x is available. 2D or 3D Optical Profiler To precisely measure the wear track with 2D or 3D, a full non-contact optical profiler can be integrated on the Tribometer platform. This advanced feature provides measurement of volume while software uses the 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 roughness, dimensions and many other surface topography studies. The optical profiler has zero influence from sample reflectivity, variations require no sample preparation and has advanced ability to measure high surface angles. Unlike other optical techniques, Nanovea optical profiler provides ability to measure any material, whether transparent, opaque, specular, diffusive, polished or rough. Large pen selection ection for varying dynamic vertical measurements. Excellent vertical and spatial resolution. The superior availability to surface topography measurement during tribological study is ideal for determining the correlation between surface characteristics and wear and friction results.
