Paper Title:
Process and Properties of Pulse Electrodeposited RE-Ni-W-P-SiC Composite Coatings
  Abstract

Process and properties of pulse electrodeposited RE-Ni-W-P-SiC composite coatings were studied. The results show that the deposited rate by pulse current is larger than that by direct current; the deposited coatings by pulse current are better than that by direct current in corrosion resistance and microhardness. And the corrosion resistance of the coatings with pulse current is better than that of stainless steel (1Cr18Ni9Ti). The duty ratio and the pulse frequency in the process of electrodeposition have a large influence on the deposition rate, the composition and the properties of coatings. SEM measurement shows that the crystals with pulse current are smaller and the surface is smoother than that by direct current. It is beneficial to make crystalline grain finer by mixing rare earth.
