Paper Title:
Effect of Different Particles Distribution on Microstructure and Corrosion Resistance of Nickel-Base Laser Cladding Coatings
  Abstract

Nickel-base composite coating reinforced by in situ synthesized multiple carbide particles were fabricated on AISI 1045 steel surface by pre-placed laser cladding. Nowadays most researches focus on the wear resistance. This study mainly focuses on the corrosion resistance property. Investigate the effect of different particle distribution on corrosion resistance of the cladding layers by controlling the amount of Zr, Ti and WC. The microstructure and electrochemical property are analyzed by scanning electron microscope (SEM) and electrochemical test equipment. The maximal particle distribution density and particle area ratio appear when Zr:Ti:WC=1:2:2. The polarization curves show that in 0.05mol/L HCl electrolyte the coatings’ corrosion resistance have positive correlation with particles distribution density and particles area ratio, and all the coatings are significantly better than 314L stainless steel in corrosion resistance.
