Microstructures and properties of NiAl–TiC nanocomposite coatings on carbon steel surfaces produced by mechanical alloying technique

TiC reinforced NiAl intermetallic matrix composite coatings on carbon steel plate were fabricated by using mechanical alloying of Ni-Al-TiC powders. The process involved trapping powder particles between the ball and cold welding together at surface. Coatings were examined using X-ray diffraction, scanning electron microscopy (SEM) and the energy dispersive X-ray spectrometry (EDS) and transmission electron microscopy (TEM). The results...
