Viscometer

11.07.2022 Riya Veluri

What is a viscometer? Viscosity is the resistance experienced by the liquid in motion. A high-viscosity (thick) liquid flows slower than a low-viscosity (thin) liquid. This can be seen by comparing the speed of oil […]

Lubricant Viscosity

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

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 [...]
