Description
Summary:For the last seven years, Oxford University and Ford Motor Company personnel have been researching jointly the development of the large-scale spray forming of steel tooling capable for use in mass production, particularly for the pressing of sheet metal in automotive applications. These investigations have involved: the comprehensive microstructure and property studies, modeling of shape evolution and heat flow, realtime feedback control of tool temperature to eliminate tool distortion, high-speed imaging and particle image velocimetry of droplet deposition on three-dimensional (3D) shapes, testing of full-scale tools for different applications in the production environment, and detailed studies of the cost and time savings realized for different tooling applications. This paper provides an overview of the scientific and technical progress to date, presents the latest results, and describes the current state-of-the-art. Many of the insights described have relevance and applicability across the family of thermal spray processes and applications.
