High-load and high-temperature tribometer – Fraunhofer IST
In all modules listed above user can change the load and velocity to automatically plot Stribeck Curves with ease. Fast Exchange makes all these modules easily swapable on the MFT platform. Loads from mN to 10,N. This test helps evaluate friction and wear parameters of piston ring liner material in presence of engine oils. The test involves rotating one ball on three stationary balls at controlled environmental conditions.
The value of any wear test method lies in predicting the dkn ranking of material combinations. Materials are tested in pairs under nominally non-abrasive conditions.
Stribeck Curve Stribeck curve is a plot between coefficient of friction and bearing number. Since the pin-on-disk test method does not attempt to duplicate all the conditions that may be experienced in service for dib lubrication, load, pressure, contact geometry, removal of wear debris, and presence of corrosive environmentthere is no insurance that the test will predict the wear rate of a given material under conditions differing from those in the test.

Work Item s – proposed revisions of this standard. Such a use of this standard is encouraged as a means to improve wear testing methodology.
All tests are done in oscillation mode under controlled environmental conditions. Temperature and recirculation addons are also available. Contact us for a live Demo or additional information. However, it must be clearly stated in any report that, while the directions and protocol in Test Method G99 were followed if truethe choices of test parameters were different from Test Method G99 values, and the test results were therefore also different from the Test Method G99 results.
The coefficient of friction may also be determined. The principal areas of experimental attention in using this type of apparatus to measure wear are described.
The ball is caused to rub against the disk 1mm stroke at a frequency of 50 Hz for 75 min. Stribeck curve is a plot between coefficient of friction and bearing number.
It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to xin. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. No other units of measurement are included in this standard.
Linear Oscillating The standard Test to determine extreme pressure, friction wear properties of lubricant greases, solid bonded films, gear and 5024 fluids, lubricating oils. Test involves slowly rotating a ring on top of material of choice. The standard Test to determine extreme pressure, friction wear properties of lubricant greases, solid bonded films, gear and hydraulic fluids, lubricating oils.
Twist Compression is designed to measure friction and adhesion in metal forming. Tapping Torque, Twist Compression, Drilling Tapping torque module allows to characterize friction, wear, torque etc.
The tests can be done in controlled environmental conditions including humidity, temperature and more. Historical Version s – view previous versions of standard.
High-load and high-temperature tribometer
Real time down force controlpiezo sensors to measure inline friction makes this module very reliable and repeatable. Piston Ring Liner This test helps evaluate friction and wear parameters of piston ring liner material in presence of engine oils.
The test setup allows to mount real pieces of actual piston ring and liners. In this latter case, the results cannot be compared to the Di data Table 2.
