Industry pays an enormous price for material degradation. The Handbook of Environmental Degradation of Materials outlines these costs, but more importantly, explains how to measure, analyze, and prevent environmental degradation for a wide range of indsutrial materials. Experts from around the world share how a diverse set of industries cope with the degradation of metals, polymers, reinforced concrete, clothing, and wood under adverse environmental conditions such as weather, seawater, and fire. Case studies show how organizations from small consulting firms to corporate giants design and manufacture products that are more resistant to environmental effects. By implementing these standards companies of all sizes should realize savings beneficial to their operations.

Paperback. Space surveillance has confirmed the increasing number of large and useless objects orbiting the Earth. Of the known 7000 objects which have a minimum size of about ten centimeters in low Earth orbit and about one metre in the geostationary orbit, only about 6% are active satellites. Over 40% are fragments of breakups of rocket upper stages and satellites. The increasing amount of man-made objects in space as a result of space operation now gives cause for concern. Several independent analyses conclude that current practices in space will eventually lead to collisions between Earth orbiting objects. The forty papers presented in this volume comprise an overview of the current situation and also outline measures which could be taken to control the growth of debris.

This Tutorial Text provides a comprehensive introduction to the subject of contamination control, with specific applications to the aerospace industry. The author draws upon his many years as a practicing contamination control engineer, researcher, and teacher. The book examines methods to quantify the cleanliness level required by various contamination-sensitive surfaces and to predict the end-of-life contamination level for those surfaces, and it identifies contamination control techniques required to ensure mission success.
