Machinability of Al 6061 Deposited with Cold Spray Additive Manufacturing

Corrosion of Cold Spray Deposited Copper Coating on Steel Substrates

The corrosion behavior of copper cold spray coatings on a carbon steel substrate was compared to that of commercially available wrought copper under the conditions anticipated in a nuclear waste repository. Corrosion potential and linear polarization resistance measurements were conducted over 90 d to 120 d in 3.0 mol/L NaCl under anoxic (1) and oxygenated-toanoxic (2) conditions to simulate th...

Hot and Cold Tensile Behavior of Al 6061 Produced by Equal Channel Angular Pressing and Subsequent Cold Rolling

The full annealing AA6061 aluminum alloy was subjected to severe plastic deformationvia the combination of equal channel angular pressing (ECAP) and cold rolling (CR) in order torefine its microstructure and to improve its mechanical properties. According to the results of hotand cold tensile tests, the combination of ECAP and CR significantly affected the final strengthand ductility of studied...

Finite Element Analysis of Cooling Time and Residual Strains in Cold Spray Deposited Titanium Particles

In this article, using finite element analysis (FEA) and an X-ray diffractometer (XRD), cold-sprayed titanium particles on a steel substrate is investigated in term of cooling time and the development of residual strains. Three cooling-down models of sprayed particles after deposition stage are simulated and discussed: the first model (m1) considers conduction effect to the substrate only, the ...
