Requirements to solid lubricants properties: good adhesion to the ceramic surface, low shear strength in the sliding direction and high compression strength in the direction of the load (perpendicular to the sliding direction). The Centre is funded by the EPSRC and aims to tackle the problems that face industry today, to develop new technologies and skills that will benefit all partners. Coupled analysis of the rotor and the journal bearing is essential in the case that [...] Read more.

The formulation and solution of the plane problem of elastic contact of a wavy surface with a half-plane is considered. Asperities of two-scale levels are taken into account—regular waviness with arbitrary shape (small-scale asperities) and regular sine-shaped roughness (large-scale asperities) epub. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields pdf. Molybdenum disulfide (MoS2) is a well-known solid lubricant for tribosystems running in vacuum or dry gases. Problems arise due to its sensitivity to humidity, which is a drawback for its application under ambient conditions. However, by using a physical vapor deposition (PVD) process, deposition parameters can be optimized not only to gain a coatings structure with favorable frictional properties but also to minimize the sensitivity to attack by water molecules download.

It was also found that the coefficient of friction increases and specific wear rate decreases with an increase in the sliding velocity, whereas specific wear rate increases with an increase in the applied normal and decreases with an increase in the sliding velocity Tribology: Key to the Efficient Engine

For this reason, it is important to be able to quantify the power dissipation and the operating temperatures already in the design stage, therefore to be able to find the best compromise between the load carrying capacity and the maximum transmittable power due to thermal limitations Lubrication: A Tribology Handbook/Order No. R-130

When the Ra roughness increases further, the contribution of deformation causes an increase in the friction after which it remains constant. Some influence of the finishing method is reported pdf.

But further than that, we can actually grab items because of the friction coefficient that exists between the skin of our hands and the surface of the element we are picking up. For instance, grabbing a piece of ice might be a frustrating task, as its friction coefficient is very low and we cannot exert the necessary tangential forces in the contact surface to keep it fixed to our hand

September 29, 2016 Due to the increasing requirements in the aerospace and automotive industries, engine and structural parts must also have an increasing life. This leads to an improvement in the fretting fatigue strength of aluminum alloys over 107 cycles, and sometimes even more. Fretting is a surface degradation process as a result of chemical and mechanical attack between two contacting surfaces by small amplitude oscillatory movement, which is closely related to fatigue, wear, and corrosion , source: Fluid Film Lubrication: A Century of Progress
