Shape memory alloys (SMAs) are a unique class of materials with the ability to recover their shape when the temperature is increased. An increase in temperature can result in shape recovery even under high applied loads. SMAs can also absorb and dissipate mechanical energy by undergoing a reversible hysteretic shape change when subjected to applied mechanical cyclic loading. These characteristics have made SMAs very popular for applications such as sensing and actuation, absorption and vibration damping. The application of SMAs spans a wide variety of industrial sectors such as aerospace...

Friction surfacing is a solid state technique that aroused interest, special to process thermo-sensitive materials, since it avoids the melted phase preventing the formation of intermetallics at in interface and the variation of the base material properties due to heat affection. These features make this technology suitable for hardfacing or corrosion protection coatings, as well as for repairing worn parts. The present study analyzed the influence of operating processing parameters in the production of coatings, using AA6082-T6 rods, over AA2024-T3 substrates. A metallurgic and mechanical...
