Modeling of Chemical Wear is a one-stop resource for students, researchers and professionals seeking quick and effective tribological evaluations of environmentally friendly and energy efficient products.This book considers optimizing additive combinations by proper methodology, bridging the gap between theory and practice. It defines effective approaches to evaluate antiwear chemical additives commonly used in industry, enhancing the mapping ability of their performance to reduce the extent of full scale evaluations.

Key Features

  • Provides full coverage of tribology in four concise chapters, including lubricants and additives and up-and-coming nano-level tribology
  • Offers effective empirical modelling of chemical wear, along with computer programs relevant to industry standards to help you improve your test methods
  • Outlines effective methodology for optimization of additive packages, relevant to the present search for eco-friendly combinations


Research and development groups for oil and lubricant industries, professional tribology societies, students and academics interested in areas of research in tribology of lubricants and design of experiments

About the Authors

A. Sethuramiah

With 38 years of research experience in basic and applied tribology, Dr Sethuramiah’s major interest lies in boundary lubrication and wear. He has worked as a UNESCO fellow and as a research scholar at Tokyo Institute of Technology during 1969-73 where he was awarded a D Engg degree. He is a past president of the Tribology Society of India (TSI) and authored the book, ‘Lubricated Wear-Science and Technology’ in 2003. Currently he is pursuing his interest in tribology research through interaction with faculty and students at VIT Vellore, IISc Bangalore, and IIT (BHU) Varanasi. He continues his association at a national level as a life member of TSI through his teaching of tribology and related subjects. Dr Sethuramiah was awarded the lifetime achievement award in R&D by TSI.
