Lubrication, one of mankind's oldest engineering disciplines, in the 19th century gained from Reynolds' classical hydrodynamic description a theoretical base unmatched by most of the theories developed in Tribology to date. In the 20th century, however, increasing demands on lubricants shifted the attention from bulk film to ultrathin film lubrication. Finite size limitations imposed constraint...

Self-lubricating polymer compounds are currently used for a wide range of applications such as bearings, gears, and water meters. Under severe conditions such as high pressure, high velocity, and/or high temperatures, the material fails (PV limit). In this study, we investigated the effect of graphite on the tribological properties of polystyrene (PS) with “ball-on-three-plates” tests. Graphite...

Although total hip arthroplasty (THA) has provided good results for over forty years, the choice of the optimal bearing surface still remains controversial. Tribology is defined as “the branch of science and technology that deals with the study of friction, wear, and lubrication”.1 Tribology is fundamental to the function and long-term survival of orthopaedic implants. With the development of h...

Tribology is an emerging technique in the pharmaceutical field for texture and mouthfeel studies. Due to its relevance oral sensory perception, tribology supports development of novel products food industry. This study explores as a tool optimise ease swallowing coatings coated tablets. We measured lubricating properties eight using two methods: surface thin film tribology. As science more adva...

Movement between contacting surfaces ranges from macro to micro scales, from the movement of continental plates and glaciers to the locomotion of animals and insects. Surface topographies, lubricant layers, contaminants, operating conditions, and others control it, i.e., this movement depends on the tribological characteristics of a system. Before the industrial revolution, friction and wear we...
