The book aims at characterizing friction and wear behaviour of sintered bearings in tribological point of view as well as their geometrical and thermal aspect considering the tribo-behaviour of a system. Each chapter dwells extensively and exhaustively on a particular design with hypothetical data analyzed and interpretations to aid the readers understanding of the design. This is thus a must read book for all involved in designing of experiments in diverse field. Frictional characteristics of sintered bearing having plain as well as additives added were studied considering process, constructional and manufacturing parameters to render it suitable lubricant in sliding contact conditions. An empirical relationship between coefficient of friction and parameters were investigated. Wear characteristics of dry sintered bearing with and without additives under different tribological conditions using dry bearing test rig were investigated. An empirical relationship between coefficient of friction and parameters were established. Using dimensional analysis technique a mathematical model considering lump parameters was developed.
