Mechanism of Lubrication with Colloidal Sols in Contacting Surfaces: The Tribology of Colloidal Sols,Used
Delivery time: 8-12 business days (International)
In the modern world there is an increased need to expand the efficiency and durability of machines and minimize energy consumption to conserve fuel resources. Machines must overcome frictional forces to perform any work and friction reduction by improved lubrication is a way of saving energy. In the past there was interest in the possibility of using liquid lubricants containing dispersed solid particles of micron size in greases and some industrial oils to reduce friction and wear. Scientists are now studying the behaviour of solid particles in the colloidal size dispersed in lubricants, system formally known as colloidal sol that have been claimed to influence friction and wear. They are present in sooted engine oils, as wear debris and as partially soluble additives. This book examines the tribological behaviour of three types of colloidal sols in lubricated contacts: metallic colloids, sooted oils and overbased detergents. Emphasis is put on the effect of slideroll ratio, particle diameter to film thickness and entrainment. This book is intended for researchers working in tribology and senior undergraduate or graduate students in mechanical engineering or chemistry.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
