Abstract

This paper will for the first time discuss a new, an innovative and world's first ever process for directly electrodepositing nanocrystalline Ni on aluminium surfaces without the need to pretreat the aluminium substrates with acid/s and pre-plate with an intermediate metallic layer. Nanomechanical test instrument was used to evaluate the mechanical properties of the as plated Ni/Al2O3/Al layers. Several partial-unloading nanoindentation tests were performed on the samples using a Berkovich probe to measure the hardness and reduced modulus of the samples as a function of contact depth. These test results will be discussed further to elucidate the mechanism of adhesion of the electrodeposited nanocrystalline Ni with the intermediate nonconductive aluminium oxide (Al2O3) layer at a nano-scale.
