Hanna, MD, Krajewsk, PE, & Schroth, JG. "Tribological Testing of Graphite and Boron Nitride Lubricant Formulations for High Temperature Aluminum Sheet Forming Processes." Proceedings of the ASME/STLE 2007 International Joint Tribology Conference. ASME/STLE 2007 International Joint Tribology Conference, Parts A and B. San Diego, California, USA. Tribological tests wereperformed on pin-on-disk tribometer, DUCOM TR-20LE-200PHM model, according to ASTM G99 standards. No external lubrication was used in the tribological testing and all tests were done at room temperature of 290C with relative humidity value of 40%.

The results indicate that the COF increases with (i) parent coal vitrinite content and (ii) decreasing rank of the Many tribological interfaces are subject to very high loads and, more importantly, high pressures. In these cases, the bodies themselves deform elastically, which can facilitate sliding in a lubricated interface. Wear tests of joint prostheses are usually performed using bovine calf serum. The results from different laboratories are hardly ever comparable as, for example, the protein concentration and the protein composition of the serum-based test liquids vary. In addition, the viscosity of these test liquids is similar to that of water and does not match the more viscous synovial fluid. The present Request PDF | Tribological Testing and Standardization at the Micro- and Nanoscale | During the last 20 years there has been an increase of publications in the area of micro- and nanotribology. Tribological Testing .

In addition, the viscosity of these test liquids is similar to that of water and does not match the more viscous synovial fluid.

A review of the literature publishedon the matter showed that there are quite a few test methods developed for wearstudies with cemented carbides, but most of them were not designed for the rockdrilling industry. 2008-05-01 Tribological Performance Testing of Industrial Greases Vincent Colantuoni, Dr. Raj Shah, Gregor Patzer, Philip Iaccarino CONCLUSIONS As seen in this poster, it is clear that standards-based tribological examination of lubricants can only be the developer’s first step in experimentation, as there are many parameters to analyzer The objectives of this paper are to: (1) review common failure modes of different types of hydraulic pumps, (2) provide an overview of the deficiencies of bench testing of hydraulic fluids, (3) review the tribological criterion for successful lubrication of vane, piston and gear pump testing, (4) review the most common pump tests reported to date, and (5) critique the quality of these tests relative to their ability … Tribological Testing of Some Potential PVD and CVD Coatings for Steel Wire Drawing Dies M. Nilsson* and M. Olsson Dalarna University, SE-781 88 Borlänge, Sweden *mnn@du.se Abstract: The aim of this study was to investigate the possibility to replace cemented carbide wire drawing dies with CVD or PVD coated steel dies. To facilitate the intelligent tribological materials characterisation i-TRIBOMAT integrates the most important tribological testing facilities at EU level with user-driven IT tools to validate new materials for components.
