چکیده مقاله:
Ni-P Electroless coatings provide appropriate resistance to wear and corrosion. Co-deposition of particles
between layers can improve their properties, especially general corrosion and erosion-corrosion behavior by means
of nano diamond as reinforcing particles. In this study Ni-P/nano diamond composite deposition were deposited on
steel substrate. Structure of the coatings and corrosion resistance of theme were investigated by scanning electron
microscopy and corrosion tests in salty media. The composite structure of the deposit was evaluated as nano size
without using any surfactants. Also results for the composite coating show better corrosion protection and higher
hardness comparing with as -deposited Ni-P. The optimum concentration of diamond nanometer particles were found
by evaluation of scanning electron microscopy pictures, hardness measurement, linear polarization and
electrochemical impedance spectroscopy results
