Abstract
Cermet materials comprising ceramic and metallic constituents demonstrate superior mechanical properties, rendering them highly appropriate for demanding applications. Studies have shown that cold spray (CS) technology is a viable method for producing cermet coatings and components. CS effectively embeds the ceramic phase, which acts as reinforcement, within the metallic matrix. Herein, a comprehensive review of diverse aspects of cermet deposits obtained using CS technology is provided, with particular emphasis on feedstock preparation methodologies and their subsequent impact on deposit characteristics. It examines the effects of several spray process parameters, feeding modes, and postprocessing techniques on the compositional and structural characteristics of the cermet deposits. The challenges and potentials are critically discussed, and future trends in the growing applications are highlighted. Aim of this study is to provide a comprehensive view on the current state of the art to facilitate the modulation of cermet deposits' performance produced using CS technology.
