Electrodeposited Ni-SiC-h/BN nanocomposite coatings: correlation between nanoparticles inclusion, microstructure and tribological properties |
| 초록 |
Nanocrystalline Ni-SiC-h/BN composite coatings were fabricated by pulse current electrodeposition process from nickel sulfamate bath. Different contents of SiC nanoparticles and h/BN nanosheets (5-20 g/L each) were dispersed in the electrolyte to investigate the effects of dispersed particles on final properties of the composite coatings. Surface morphologies, microstructures, mechanical and tribological properties of the electrodeposited composite coatings were evaluated by using scanning electron microscopy (SEM), optical microscope, X-ray diffraction (XRD), vickers microhardness, wear and coefficient of friction. Studies revealed that as compared to pure nickel coatings, electrodeposited Ni-SiC-h/BN composite coatings exhibited smooth and compact surface, increase in vickers microhardness, grain refinements and enhanced tribological properties. In addition, as compared to either of Ni-SiC or Ni-h/BN composite coatings, presence of both types of particles together into nickel matrix revealed overall improved performance. |
