Cold Gas Dynamic Spraying (CGDS), or simply Cold Spray has vividly captured worldwide attention in the last few years. The number of peer reviewed papers in scientific journals and international conferences has grown exponentially as well as the number of researchers and scientists developing and/or using the process. The reported studies on CGDS have been mainly focused on process development and applications. Process development studies include a wide range of theoretical and experimental work looking at nozzle design, spraying parameter effects and optimization as well as particle deformation and bonding mechanisms upon impact with the substrate. Applications studies have revealed that a wide variety of materials, such as copper, aluminum, nickel, titanium and their alloys can be sprayed using the CGDS process.
Despite all these studies, very few economical analyses of the process have been reported, leaving the economic viability of the CGDS process up for speculation based on fragmental or incomplete analysis. This paper aims at performing a thorough economical analysis of coatings for aeronautics components produced by CGDS and compare the results with similar coatings produced by HVOF and plasma spraying. A few typical coatings are chosen for this study as well as a few typical components to be sprayed on in order to get a study as broad as possible to determine niche that are economically viable for CGDS.
