Influence of Cold Spray Parameters on Bonding Mechanisms: A Review

The cold spray process is governed by the impact of high velocity feedstock particles onto a substrate without melting. Hence, bulk material properties are retained. However, it challenging to achieve good adhesion strength. strength depends on factors such as parameters, conditions, coating/substrate interactions at interface and properties. This review examines fundamental studies concerning mechanisms technology considers effect input parameters temperature, stand-off-distance, pressure, gas, angle, traverse speed torch bonding mechanism Furthermore, effects conditions hardness, roughness highlighted. properties, feed rate, shape size summarized. Understanding these necessary obtain optimal that enable best interfacial for range combinations. It expected spherical morphology small particle (<15 ?m) provides when deposited mirror-finished surface using pressure spray. Deep insights into each parameter exposes uncovered potential an additive manufacturing method.
