Effect of carrier gases on microstructural and electrochemical behavior of cold-sprayed 1100 aluminum coating
1100 Aluminum has been cold sprayed onto similar substrate using 100 vol.% He and mixture of He–20 vol.% N2 as carrier gases. Analysis and characterization of sprayed depositions under different processing conditions was performed through optical micrography, stereological analysis, scanning electron microscopy, and microhardness depth profiles. Potentiodynamic polarization curves and Tafel ext...
متن کاملTransmission electron microscopy of cold sprayed 1100 aluminum coating
Cold-spraying of 1100 Al powder particles onto 1100 Al substrate was accomplished using carrier gases 100 vol.% He and a mixture of He–20 vol.% N2. TEM characterization correlates very well the occurrence of dislocations, presence of oxide, and surface instability phenomenon with observed mechanical and corrosion properties of the cold-sprayed coating. 2005 Acta Materialia Inc. Published by Els...
متن کاملSliding-induced Microstructure of Cold-Sprayed Copper Coating Observed by Electron Channeling Contrast Imaging
Cold gas dynamic spray is a coating process for fabrication of materials that are sensitive to heat and oxidation such as copper [1]. In cold spray, the particles are accelerated to supersonic velocities typically between 500 1200 m/s [1]. Upon high speed impact, the cold sprayed particles undergo extensive plastic deformation at very high strain-rates (up to 10 9 s -1 near impact interfaces), ...
متن کاملCorrosion 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...
