Paper Title:
Pulse Electrodepositon of Ni-W-P-CeO2-SiO2 Composite Coatings
  Abstract

Square-wave pulse current was used to electrodeposit Ni-W-P-CeO2-SiO2 composite coatings. The influence of pulse on-times, off-times and peak current densities on properties of the composite coatings was researched. The microhardness, chemical compositions and microstructures were evaluated by EDX, SEM and microhardness tester. The results show that the composite coatings possessed higher microhardness and fine-grained structure. The crystal sizes of the composite coatings were found initially to decrease with the rise of pulse on-times before it started to increase with further increasing pulse on-times. Decreasing pulse off-times or increasing pulse peak current densities resulted in considerable refinement of crystal sizes.
