Electroless, Composite Coating, FESEM-EDAX, Hardness, Ni-P-CNF Coatings.


In the current experimental work, the electroless Ni-P-CNF nano-composite plating has been deposited upon
basic mild steel substrate. The activated 1.5 gpl CNF nano-particles were integrated into an acidic electroless
Ni-P matrix as a second phase material and were condensed by a reducing agent named as sodium
hypophosphite. After coating, as-prepared Ni-P/Ni-P-CNF EL deposition were heated at 350C in Ar
environment for one hour duration and were analysed for surface morphology and elemental composition by
SEM and EDAX. A homogeneous and heavy consistent allocation of CNF nano-particles into EL Ni-P matrix is
established through analysis of SEM and EDAX. The hardness (HV50) is measured by micro-hardness tester.
The micro-hardness of the substrate, Ni-P coated sample and Ni-P-CNF coated samples are in subsequent order
as Ni-P-CNF (heated) > Ni-P-CNF (as-coated) > Ni-P (heated) > Ni-P (as-plated) > MS
