The test involves rotating one ball on three stationary balls at controlled environmental conditions. No other units of measurement are included in this standard. The principal areas of experimental attention in using this type of apparatus to measure wear are described.
High-load and high-temperature tribometer – Fraunhofer IST
The tests can be done in controlled environmental conditions including humidity, temperature and more. Real time down force controlpiezo sensors to measure inline friction makes this module very reliable and repeatable.
The coefficient of friction may also be determined. Link to Active This link will always route to the current Cin version of the standard.
High-load and high-temperature tribometer
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 use.
Tapping Torque, Twist Compression, Drilling Tapping torque module allows to characterize friction, wear, torque etc. Fast Exchange makes all these modules easily swapable on the MFT platform.
The test setup allows to mount real pieces of actual piston ring and liners. Contact us for a live Demo or additional information.
Loads from mN to 10,N. All tests are done in oscillation mode under controlled environmental conditions. Stribeck Curve Stribeck curve is a plot between coefficient of friction and bearing number. Linear Oscillating The standard Test to determine extreme cin, 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 fin. The standard Test to determine extreme pressure, friction wear properties of lubricant greases, solid bonded films, gear and hydraulic fluids, lubricating oils.
The ball is caused to rub against the disk 1mm stroke at a frequency of 50 Hz for 75 min. Thank you for your interest and filling out the dim The value of any wear test method lies in predicting the relative ranking of material combinations.
Work Item s – proposed revisions of this standard. Since the pin-on-disk test method does not attempt to duplicate all the conditions that may 50234 experienced in service for example; 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.
ASTM G99 – 17 Standard Test Method for Wear Testing with a Pin-on-Disk Apparatus
Test dih slowly rotating a ring on top of material of choice. Temperature and recirculation addons are also available. Materials are tested in pairs under nominally non-abrasive conditions.
Piston Ring Liner This 503224 helps evaluate friction and wear parameters of piston ring liner material in presence of engine oils. In this latter case, the results cannot be compared to the ILS data Table 2.
In all modules listed above user can change the load and velocity to automatically plot Stribeck Curves with ease. Such a use of this standard is encouraged as a means to improve wear testing methodology. 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 5324 different from Test Method G99 values, and the test results were therefore also different from the Test Method G99 results.
This test helps evaluate friction and wear parameters of piston ring liner material in presence of engine oils. Stribeck curve is a plot between coefficient of friction and bearing number.
