Abstract

TiN-coated aluminum pigments were prepared by nanoparticle-bonding technology of high-energy ball milling. The effect of ball milling on the morphology and evolution of the composite powders was investigated via field-emission scanning electron microscopy, transmission electron microscopy, and particle size distribution analysis. Results show that the TiN nanoparticles bonded to the surface of aluminum microflakes under the action of a mechanical force but in the absence of any binder. A uniform nanoparticle coating formed on the surface of the flake aluminum microparticle. The optical reflectance of the TiN/Al composites was measured within 200 nm to 2500 nm wavelength. The reflectance gradually decreased as the milling time was prolonged.
