Brake Material Screening - (AN1013)
Using the UMT TriboLab it is now possible to test brake pad and rotor materials in real time and easily program industry-standard dynamometer protocols and standards, all while monitoring key parameters such as friction, temperature, sliding speed, and vibration. This application note describes the technique and demonstrates its very good correlation to tests executed on the full-scale dynamometer following the SAE J2522 standard (known as AK Master).
Evolution of OCP During Tribocorrosion - (AN1010) 1.4MB
This application note discusses how Bruker’s UMT TriboLab combines tribology and electrochemistry capabilities into one system to provide a better solution than traditional electrochemical measurements for tracking the evolution of OCP during a tribocorrosion test.
Characterization of Lubricants for Research Development, Quality Control and Application Engineering - AN1000 1.6 MB
This application note provides an overview of lubrication science and engineering and then discusses the latest methods for comprehensively characterizing the performance of lubricants in nearly any application.
Thin film and coating testing using the UMT testers - AN1001 2.3 MB
This application note discusses how the use of simultaneous measurements from integrated instrumentation has resulted in a number of interesting applications in the study of mechanical properties of thin films and coatings.
Automotive Applications for Tribometers - AN1002 2.0 MB
This application note discusses a sampling of the many automotive component and material tests possible with a flexible, high-performance tribometer.
Generating a Stribeck Curve in a Reciprocating Test - AN1004 620 kB
While classical Stribeck curve generation is done using a unidirectional test, it has been a challenge to obtain similar evaluations of lubricants and surface treatments using a reciprocating motion test. Bruker's Universal Mechanical Testers are equipped with high-speed linear oscillatory stages and adjustable stroke lengths and frequency ranges, as well as the measurement capabilities and companion software data reduction algorithms, to perform such characterization.
Scratch Testing of Nanofilms for Flexible Electronics - AN1012 1.0 MB
This application note discusses the capabilities of Bruker’s scratch test system and provides an example of its evaluation of a metallic nanofilm on a polymer substrate.
