Surprisingly, when two lubricated solids are heavily loaded against one another and when a motion is applied to the solids surfaces, these two solids may not be touching one another (see Figure 1, left)! This […]

Modeling rough adhesive surfaces

09.01.2016

Imagine a new type of tyres whose structure has been designed to have greater adhesion on the road. Quite a timely discussion during the long winter nights. French physicists have now developed a model to [...]
Thin-Film Sensor for in Situ Measurement of Temperature Rise in Rolling Contacts

02.11.2021

The optimization of lubricated rolling contacts with regard to friction and wear is an engineering challenge due to the complex mechanical, chemical and thermal stresses in the surface near area. Calculation models are used to [...]
Insights to the tribology of toothpaste

02.01.2024

Texture is a commonly used term that encompasses the multi-dimensional sensory characteristics influenced by a material’s structure at both macro and micro-levels. Also, the rheology and surface properties of products that come into contact with [...]
Making Lubricants From Plastic Waste

30.03.2020

Single-use plastics have a bad reputation for contributing to the earth’s environmental and pollution issues. With the world’s ever-vigilant focus on protecting the environment, society is determined to halt the use of single-use plastics, such [...]

Reciprocating Sliding Friction and Wear test

10.04.2023

Friction and wear are two important factors affecting mechanical components’ performance and durability. Reciprocating sliding friction and wear tests evaluate the tribological properties of materials and coatings under simulated sliding conditions. These tests can provide [...]
