Automated Analysis and Control System for Optimization of Inorganic Stripping Processes

ABSTRACT: Stripping and reapplication of inorganic coatings is a necessary step in the lifecycle management of aircraft components. As the baths for stripping are used, the strip rates and quality of the stripping can vary resulting in inefficient processing. Inefficient processing can drastically increase the time required to service a component. Information is needed to determine the factors that cause these changes, the optimal process window, and allow determination of the limits of a stripping solution. To address this, Figure Engineering intends to develop an automated analysis and control system for stripping baths. This system will continuously monitor key components of each stripping bath and perform selective electrochemical filtration to maintain them at optimum levels. BENEFIT: Figure Engineering anticipates the results of Phase I work will validate the feasibility and need for immediate pursuit of Phase II efforts. Figure Engineering anticipates that the optimization of metal stripping processes will provide DoD and aerospace industry with a faster and more reliable means for the removal of deposited coatings on aircraft components. It also allows for significant man-hour savings, reduced process flow days and inventory cost avoidance. This process improvement will lead to a reduction of the following 1) production floor space, 2) energy consumption, 3) line maintenance and 4) process chemical waste.
