Paper Title:
Effects of Ultrasonic and Mechanical Stirring on Microstructures and Properties of Nano-Composites
  Abstract

Ni-W-P/CeO2-SiO2 nano-composites were prepared on carbon steel surface by pulse co-deposition of Ni, W, P, CeO2 and SiO2 nano-particles. The influence of ultrasonic time and mechanical stirring on microstructures and properties were researched, and the characteristics were assessed by chemical compositions, element distribution, deposition rate, microhardness and microstructures. The results indicate that the nano-composites possess compact microstructures, clear outline of spherical matrix metal crystallite, fine crystal size, and uniform distribution of nano-particles within Ni-W-P matrix metal when treated by ultrasonic of 30mins and mechanical stirring of 1000rpm. An increase of the mechanical stirring velocity leads to refinement in grain structure and the corresponding increase of the deposition rate and the microhardness.
