Special Advanced Studies for Pollution Prevention. Delivery Order 0046: Advanced Studies in Pollution Prevention Chrome Replacements for Internal and Small Parts

摘要

This document is a Technology Analysis assessing the current state of the art in coatings and surface treatments that could be used to replace hard chrome plating on internal diameters (IDs) and heat-sensitive aircraft components. Its purpose is to determine which technologies and materials are viable options for the Joint Strike Fighter (JSF), and estimate what developments will be needed to bring these options to production at original equipment manufacturers (OEMs) and overhaul and repair (O AND R) sites, most of which are military depots. The analysis included assessment of written information, including scientific and technical data and trade literature, combined with extensive discussions with manufacturing engineers, development engineers and scientists, depot personnel, and equipment and service providers.
