Description of the book

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 of the book

  • 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
