Tribometer has found essential usage in the manufacturing sector and is used to measure tribological quantities˳ This article discusses the functionality of the tribometer and the different types of tribometers available˳
A tribometer instrument is used by specialists in the manufacturing industries and other sectors to measure tribological quantities˳ This includes things like testing the friction force, constant friction and the wear volume in between two different surfaces˳ Read on to know more˳
Tribometers helps to determine the level of wear and friction as two different surfaces rub with each other˳ As an example, one measurement method can involve the use of a spherical or flat device that is positioned on the test sample with a precise weight˳ This test sample could either be reciprocating or spinning in a linear track˳ During the testing, the frictional forces between the sample and the device will be measured˳ In addition, a calculation will be done on the volume of material lost during testing to determine the wear for the device and the sample˳
With this simple method, the specialist can study and determine the wear and friction actions of nearly all combination of solid materials using contact pressure, varying times, temperature, velocity, humidity and so on˳
In general, tribometers are classified based on the contact arrangement that is simulated or by the developer of the original equipment˳ Some of the different types of arrangements include the Bouncing Ball, Four Ball, Pin on Disc, Twin Disc, Block on Ring and SRV test machine˳
Here is a brief overview of the different arrangements to help you make the right choice when choosing a tribometer˳
The Bouncing ball tribometer is made of a ball that is impacted against the surface at a certain angle˳ In a typical testing, the ball will slide on an angle across a track before impacting and bouncing off the surface˳ This friction that is caused when the ball make contact with the surface will result in a rotating force on the ball and a horizontal force on the test surface˳ One of the ways that bouncing ball devices are used would be to determine how lubricants react under extremely high pressure, like in gears or ball bearings˳
A Four Ball tribometer is an excellent device for quality check and development˳ Testing with this device allows for repeatable actions as the one ball on top and three balls at the bottom make a unique configuration for repeatable and stable contact˳ This tribometer can be used to identify extreme pressure properties; the friction action of lubricants and wear preventive properties˳ Since this four ball instrument delivers quick results and cost effective samples, it is the ideal device for R&D projects˳
The Pin on disc tribometer has a stationary pin below an applied load that connects with a rotating disc˳ Spherical pins are generally used for simple geometry contact˳ But the pin could have any shape in order to simulate a contact˳ This device has proved to be very useful in facilitating a simple friction and wear testing for low coatings˳
