Abstract

 The present study illustrates the mechanical properties of Ni- TiO2 composite coatings, electrodeposited on
steel substrate. Titanium oxide nanoparticles were codeposited with Ni on a EN 8 steel substrate using pulse electro
deposition method. The experiments were carried out using different combinations of pulse parameter using response
surface methodology and the trials were conducted to study the effect of pulse parameters.The micro structure, hardness
and coating strength were studied by means of SEM, XRD, micro hardness tester and scratch tester. Evaluation of the
coated surface represents the improved micro-hardness value about 10 to 20 percent of the base material. The adhesion
and scratch test show the coating done at optimum value of the parameter like frequency, duty cycle and current density
results at high bonding between the coating and the surface.
