Mechanical Behavior Of Cold Spray Additively Manufactured Titanium Parts

Cold spray is a technology that uses a supersonic jet stream of metal particles to produce a deposit on a substrate surface. Bonding between particles is caused by intense plastic deformation during high-velocity impact. This deposition technique has been used mainly as a coating technology or for repair of worn/damaged surfaces. However, the use of cold spray has expanded to the additive manufacturing field because the supersonic jet allows fast growth of the deposit, and also because of its theoretically unlimited manufacturing space when coupled with robotic arms. In this regard, the mechanical properties of the sprayed part are influenced not only by the process parameters but also by the robot kinematics. This research will focus on the analysis of the mechanical behavior of titanium cold sprayed parts and the effects of post heat treatment on tensile strength.
