Abstract : Military weapon systems face tradeoffs of performance, cost of production and maintenance versus long term durability and reduced reliability resulting from corrosion. The thesis of this presentation is to show a few examples of some specific designs, processes and materials which we have found to have significant advantages in this tradeoff by their excellence of protection with minimum penalties. These details of successful experience set the stage for two other theses. The first is that the data incorporated in U.S. Military Documents, such as the requirements in MIL-F-7179 (Protection of Aerospace Weapon Systems), MIL-STD-1568 (Materials and Processes for Corrosion Control), and the excellent base from which to begin the design of a weapon system. But it is an almost impossible situation to try to spell out the details required to actually obtain performance excellence in the design tradeoffs, or to define the required intricate details necessary to accomplish optimum protection from the pervasive thermodynamics of materials seeking lower free energy states. A final thought is that, in conjunction with our base of detailed requirements plus an intelligent selection of materials and manufacturing options. We need valid test methods to tell us early in the equipment production cycle if we have been successful in our efforts to produce durable and reliable structures and electronics.
