| Abstract: | It has been proved that the electrolysis parameters strongly influence the structural properties of nickel electrodeposits,
mainly the crystalline growth, preferred orientation and surface morphology. To determine the structural characteristics of
nickel and composite nickel matrix electrocoatings, prepared under either direct current or pulse current conditions, the
electron microscopy techniques have proved very important tools. In particular, investigation of the distribution and percentage
of microparticles incorporated in the metallic matrix during preparation of nickel composite electrocoatings demands the use
of techniques such as energy dispersion spectroscopy (EDS) or image analysis. |
