Sliding-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 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 کاملEffect of Alkali and Heat Treatment on Biomimetic HA Coating on Ti6Al4V
In this study, time of calcium phosphate formation on Ti6Al4V alloy with or without alkali and heat treatments was investigated. Specimens were soaked in 0, 5, 10 M solutions of NaOH at temperatures of 60 or 80 °C for 24, 72 h. Their surfaces were characterized using scanning electron microscopy and thin film X-ray diffraction. It was found that optimum condition is 72h soaking in 5 M NaOH in 8...
متن کاملDeposition efficiency, mechanical properties and coating roughness in cold-sprayed titanium
In the cold-spray process, metal powder particles develop into a coating as a result of ballistic impingment on a substrate. In cold-spray, compressed gas (air, nitrogen or helium), at pressures ranging between 1.4– 3.4 MPa (200–500 psi), but typically around 1.7 MPa (250 psi), flows through a manifold system containing a gas heater and a powder feeder. The pressurized gas is heated electricall...
متن کاملEffect 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...
