| Abstract Scope |
Cutting tools require superior wear resistance to perform effectively machining operations. While chemical vapor deposition (CVD) and physical vapor deposition (PVD) coatings are commonly used to enhance surface thermal and wear properties, their limited thickness, typically a few microns, makes them prone to rapid degradation during cutting applications. This study investigates cold spray as a promising alternative for enhanced wear-resistance coatings for cutting tools. A metal-ceramic composite (cermet) feedstock was used to deposit coatings under varying substrate conditions. Post-deposition heat treatment under different conditions was performed to further enhance the coating properties. A comprehensive analysis of the microstructure and mechanical characteristics was conducted to better understand the underlying mechanical properties governing the performance of these cermet coatings. The results highlight the potential of the cold spray coatings for advanced applications in the metal cutting industry. |
