Abstract
This study investigates the microstructure, the mechanical properties, the topography and the tribological behavior of a composite cold spray coating, consisting in a 410L matrix and M2 tool steel reinforcements. The surface finish creates protuberances due to the presence of M2 particles. A lubricated reciprocating sliding test was performed for the composite and for other two coatings, for comparison. The analyses revealed the presence of a tribofilm, leading to low friction and negligible wear even in harsh conditions. This study opens the interest for surface textures with protuberances and the use of cold spray process to easily produce them.
