AB  - Fine-grained  nickel  coatings  were  electrodeposited  by  direct  current  (dc)  regime  onto  different  substrates:  polycrystalline  cold-rolled  copper,  polycrystalline  brass  and  single  crystal (100)-oriented silicon. These composite structures belong to different type of laminated composite systems. The influence of the substrate material and coating plating parameters on microstructural and mechanical properties, such as hardness and adhesion, was characterized by the Vickers microindentation test for different loads. Above critical indentation depth (usually around  10%  of  the  coating  thickness),  the  measured  hardness  is  the  so-called  “composite  hardness”,  because  the  substrate  participates  in  the  plastic  deformations  during  indentation.  Three composite hardness models (Korsunsky, Chicot-Lesage and Chen-Gao), constructed on different principles, were chosen for fitting the experimental results in order to determine the coating hardness and the critical reduced depth as the adhesion parameter. The coating hardness is mainly influenced by the current density, because increase in current density leads to decrease in grain size and increase in coating hardness. The critical reduced depth as the parameter of adhesion depends on the substrate material.

AB  - Multilayer composite structures of electrodeposited Ni films on polycrystalline copper substrates were fabricated with the assistance of ultrasonic agitation. Alternate ordinary and ultrasonicassisted electrodeposition of Ni layers allowed the formation of laminated films. The adhesion and hardness properties were characterized using bidirectional bending test and Vickers microhardness test with different loads. Dependence of composite microhardness and film adhesion on layer thickness was investigated. It was confirmed that densified parallel interfaces give rise to high hardness and strength of composites. Model of Korsunsky was chosen and applied to experimental data for obtaining the film hardness and model of Chen-Gao was applied for the adhesion evaluation. Compared with the conventional electrodeposited Ni films, the mechanical properties of the ultrasonic-assisted multilayer Ni films are improved. The microhardness and adhesion of the films are enhanced by introduction of ultrasound and by reducing the layer thickness in the film.
AB  - Višeslojne kompozitne strukture su sačinjene od elektrodeponovanih filmova Ni na supstratima od polikristalnog bakra uz pomoć ultrazvučnog mešanja. Naizmenična elektrodepozicija slojeva Ni bez i uz pomoć ultrazvučnog mešanja omogućila je formiranje laminatnih filmova. Adhezija i tvrdoća su okarakterisane ispitivanjem na savijanje u dva pravca i Vikersovim testom mikrotvrdoće sa različitim opterećenjima. Zavisnost kompozitne mikrotvrdoće i adhezije filma od debljine sloja je ispitana. Potvrđeno je da veliki broj međuslojnih granica doprinosi povećanju tvrdoće i jačine kompozita. Za obradu eksperimentalnih podataka su odabrani i primenjeni model Korsunskog za izračunavanje tvrdoće filma i model Čen-Gao za procenu adhezije filma. U poređenju sa filmovima Ni elektrodeponovanim na konvencionalan način, mehanička svojstva filmova elektrodeponovanih u prisustvu uzltrazvuka su poboljšana. Vrednosti mikrotvrdoće i adhezije su povećane uvođenjem ultrazvuka i smanjenjem debljine pojedinačnog sloja Ni u filmu.
