Ceramic Coatings via Friction Stir Processing: Challenges and Drawbacks for Industrial Applications

Abstract

The scope of this article is to highlight the limits of Friction Stir Processing (FSP) as a method for producing metal-matrix compositesurface layers. Compared to other processes for ceramic coatings, FSP is an uncomplicated technique that presents many advantages in term of costs and environment protection. Still, there are some unresolved problems before further industrial-scale applications of friction stir processing as additive manufacturing technology. This paper focuses on aluminum alloys since they are widely used materials for the aircraft and automotive industry and the challenges encountered in coating via FSP are similar to other materials.
