Drawing together expertise in this multidisciplinary field, this volume assists in a better understanding of the issues relating to environmental design. Tribology in Environmental Design 2000 provides an excellent opportunity to present to the product designer the wider tribological implications on the whole life-cycle of the product. This includes manufacturing processes and the product's use phase, which need to be considered if companies are to satisfy environmental criteria. TOPICS COVERED INCLUDE: - Life-orientated Products - Product Life Design Tool - Life-cycle Assessment for Optimised Products - Surface Engineering - Lubricants - Test Methods - Advanced Materials - l - Analytical Studies - Advanced Materials - ll - Author's Index
