Her research interests include nano-surface-engineering for tribological and biomedical applications, with emphasis on fabrication and nanomechanical and tribological characterization. Comparing with SFA experiments, it is shown that the pull-off force and separation displacement can be predicted by the GW model and that the pull-off force strongly depends on the standard deviation of surface height, causing the broad distribution of pull-off force at rough surfaces.

Bhushan,Bharat; Sayer,Robert,A, 2007, "Surface characterization and friction of a bio-inspired reversible adhesive tape." If the angle of the plane is increased there will be an angle at which the body begins to slide down the plane. June 06, 2013 Paper-based composite friction material is a kind of key functional material for automatic transmission. Since this coating is not dense enough to provide good sealing, it can cause the faces to leak at shutdown.

Ans: Bearings are designed with a specific internal clearance to allow free rotation of rolling elements, to compensate the thermal expansion, and to distribute load on rolling elements. Tribology refers to the study of friction, wear, lubrication and contact mechanics, particularly in and engineering and mechanical context. Finally, transmission electron microscopy verified the amorphous nature of the formed tribolayer which is in a good agreement with literature.

MATERIALS LETTERS 29, no. 4-6, 221 - 227. These conditions are equvilent to a combined pressure and speed factor values of 0.141–5.664 MPa m/s. Dezember 2016 erfüllen: Zertifizierung nach DIN EN ISO 50001 oder EMAS. We are searching for a Manager for the Semiconductor Device Sciences Department for the Albuquerque facility. Is the thrust sliding bearing same as tilted pad/Michelle’s pad bearing? O-ring grooves can be damaged limiting their ability to seal effectively. By means of continuous friction and wear measurement, lubricated steel-steel and steel-aluminum contacts were evaluated.

The results showed an excellent improvement in anti-wear, anti-friction, and extreme pressure properties. Professor Komvopoulos’ near-term research plans include nanostructure material synthesis, nanoscale contact electromechanics, multi-functional probes and surface templates, self-adapting surfaces and interfaces, bioassays and biomimetic surfaces, nanomanufacturing, mechanics of biological surfaces, biomimetic materials, and synthesis of scaffolds with special cues for enhanced biofunctionality.

Recently, intensive studies of superlubricity (phenomenon of vanishing friction) have sparked due to high demand in energy savings. The value of resistance of an oil film formed between the worm and the worm-wheel was accepted as the criterion of the existing type of friction in the meshing during mating of these two elements. Proceedings of the Institution of Mechanical Engineers, Part J: Journal of Engineering Tribology. November 30, 2015 In this work, the effects of preload factor on the stability performance of noncircular two and three lobe journal bearings with incompressible micropolar lubricant are presented based on the linear and nonlinear dynamic models.

Burton,Zachary; Bhushan,Bharat "Surface characterization and adhesion and friction properties of hydrophobic leaf surfaces." The results show the relationship between the friction coefficient and the hot stamping parameters well. The date on your computer is in the past. The objective was to identify mechanisms explaining the experimentally observed lubricating properties of the two amorphous films. [...] Read more. Conceived to be modular in manufacturing, this test system can adapt easily to various requirements in surface and coatings testing.

Credit: Tomlison et al (2013) In this particular case, there are two friction mechanisms that are added to the overall friction value: dry friction, which accounts for the energy required to slide tangentially two parallel surfaces; and ploughing friction, which accounts for the energy required to deform an elasto-plastic surface in order to continue with the tangential sliding. The intention was to get dependable data on the forces, coefficient of friction, apparent contact area and actual contact area.
