摘要：

ZrO2-CeO2 nanocomposites are well known for their superior mechanical, thermal and tribological properties. On the other hand, Ni-P electroless coatings are in widespread industrial usage. In this work, we attempted to assimilate the lab-made ZrO2-CeO2 nanocomposite into Ni-P electroless coating to achieve synergistic property enhancement through composition optimization. Several techniques thoroughly characterized both the as-prepared nanocomposite powder and the Ni-P-ZrO2-CeO2 composite coating. The results proved that the nano composite assimilation refined coating surface morphology and boosted mechanical, tribological and corrosion resistance properties. Post-high-temperature annealing at 350 degrees C, significantly improved the coating performance, which was attributed to the annealing induced morphology refinement and crystallization.
