摘要：

TiC-reinforced Ni3Al intermetallic matrix composite coating on steel was fabricated successfully using the combustion synthesis reaction of 3Ni-Al-Ti-C system during casting. X-ray diffraction (XRD), scanning electron microscopy (SEM) and energy-dispersive spectrum (EDS) are used to analyze phases, microstructure and composition of the coating and the interface. The results show that the coating is composed of Ni3Al and TiC. In the coating, TiC particulates with dimension of 1-2 mu m are relatively uniformly distributed in Ni3Al matrix. The coating is compactly formed on steel with a metallurgical bonding interface. The wear resistance of the coating is 4.3 and 23.4 times higher than that of steel substrate at the room temperature and 400 degrees C respectively. (c) 2006 Elsevier B.V. All rights reserved.
