Implementation of the Chicot–Lesage Composite Hardness Model in a Determination of Absolute Hardness of Copper Coatings Obtained by the Electrodeposition Processes

The influence of various electrolysis parameters, such as the type cathode, composition electrolyte and time, on morphology, structure hardness copper coatings has been investigated. Morphology were analyzed by scanning electron microscope (SEM), atomic force (AFM) X-ray diffraction (XRD), while coating was examined Vickers microindentation test applying Chicot–Lesage (C–L) composite model. Depending conditions electrolysis, two types Cu obtained: fine-grained mat with a strong (220) preferred orientation from sulfate smooth mirror bright (200) added leveling/brightening additives. showed larger both measured calculated than coatings, that can be explained phenomena boundary among grains. Independent conditions, critical relative indentation depth (RID) 0.14 established for all separating zone in which equaled requiring an application C–L model determination absolute coatings.
