“God made the bulk; surfaces were invented by the devil”, a Nobel prize winning physicist Wolfgang Ernst Pauli said. In tribology, as in many other sciences, surface features (asperities, roughness) play an important role. In […]
Tiny particles are all over around us and sometimes they may create problems. This is especially of concern with metal particles formed due to wear in man-made engineering devices. Particles formed in car disk brakes […]
A nice article regarding the wear particles analysis in Machinery Lubrication, look further: http://www.machinerylubrication.com/Read/526/fatigue-wear-particle-analysis.
Nordtrib 2016 came to a close last Friday and I returned home inspired and energized for the next stint in my PhD research. This post is an overview of the conference and summarises the outlook […]
Currently, a large portion of consumed energy is used to overcome friction. Design of low friction components is a primary goal in building a sustainable society. Superlubricity, the state of ultralow friction (<0.01), has already […]
Leonardo di ser Piero da Vinci, the famous Italian engineer, architect, painter, musician, mathematician can also be considered as The First Tribologist! Although the term itself was invented approximately 450 years after Leonardo da Vinci […]
The increasing awareness on environmental pollution caused by many chemicals, including lubricants, promotes the use of environmentally friendly products. There is a clear trend towards a more responsible use of lubricants and several legislations already […]
Carbon-based nanomaterials, coatings and films attracted a great attention due to proved possibility to achieve lowest friction and wear without environmental pollution. However, frequently, the state of the low friction is strictly related to the […]
Glycerol is a highly viscous liquid, generating friction coefficient of 0.1 and up for bearing steels in boundary lubrication. In full film EHL, pure glycerol generates high friction as well and therefore is rarely used […]
Friction is a result of complex interaction of physical, chemical and mechanical forces at the sliding interface. Due to mentioned complexity, truly predictive models of friction are yet to be developed. As a result of […]
