AB  - A series of Ni þ WC composite coatings were obtained by electrodeposition on a rotating disc electrode (RDE)
from a commercially available Watts bath containing additives for brightness and smoothing and insoluble WC
particles, using either constant or pulsating current. It was shown that the amount of WC embedded in the coating
could vary from a few percent to over 80% depending on the rotation rate and the current density of deposition.
Higher amounts (over 50 mass%) of embedded WC particles could be obtained only at rotation rates higher than
2000 rpm. It was also shown that the concentration of insoluble WC particles in the Watts bath has no significant
influence on the amount of WC embedded in the coating, enabling the use of dilute mixtures (2 mass%ofWC in the
solution). At higher amounts of embedded WC particles, rough deposits were obtained with the WC particles being
mostly incorporated in agglomerates of different sizes (from about 50 lm to about 100 lm). It was also shown that
under the same conditions of electrodeposition, higher amounts of embedded WC particles could be obtained from
solutions containing smaller particles.

AB  - The modification of glassy carbon by immersion in AgNO 3 solution was studied by cyclic voltammetry, vacuum techniques (AES and XPS) and STM. The influence of Ag + concentration, time of immersion, the presence of oxygen in AgNO 3 solution and previous thermal treatment of the glassy carbon were examined on 'as received' (untreated), polished and electrochemically treated samples. The results show that glassy carbon electrode immersed in AgNO 3 solution is modified by silver, which is deposited in its elemental state on the surface and near surface layers of the material. Cyclic voltammograms of silver-modified glassy carbon electrodes are similar to those of a silver electrode. The quantity of silver deposited on glassy carbon strongly depends on the pretreatment of the material before its immersion. The results obtained suggest that functional groups participate in the reduction of Ag + , and thus in the electrode modification, as active centers. Metal particles are not uniformly deposited on the surface and the deposition is 3-dimensional with deposits of laminar structure. A mechanism for the modification process is proposed.

AB  - Electrochemical properties of glassy carbon electrodes of two types were examined, one thermally treated at 1000°C (sample K) and another thermally treated at 2500° (sample G). Mechanically polished or electrochemically polarized electrodes were characterized in NaOH, HClO 4 and H 2 SO 4 solutions by cyclic voltammetry (cv) at different sweep rates in the potential range between the hydrogen and oxygen evolution. The activity of the electrodes depended on the properties of the glassy carbon examined, as determined by both the temperature of thermal treatment and the mechanical or electrochemical pretreatment of the sample. It was noticed that both types of electrodes, when polished exhibited an increase in the double layer charge upon increasing the pH value of the solution. The cv charges, for both types of samples, increase upon anodic polarization. The higher the potential of oxidation, the more pronounced is the increase in charge, particularly in acidic solution. The increase in charge amounts from below 1 mC cm -2 for polished glassy carbon up to few hundreds of mC cm -2 for surfaces anodically polarized in acidic solution. Analysis of the dependence of voltammetric charge, as well as morphological changes of the electrode surface, on the time of oxidation suggests the existence of three stages in the electrochemical activation process. The first one occurs only once at the beginning of the activation, while the other two repeat themselves, reflecting a periodical activation and deactivation process. These stages were discussed and ascribed to a surface layer oxidation, graphite oxide layer growth and mechanical destruction of the surface. Independent surface analysis by AES, XPS and STM confirms the results obtained by electrochemical methods.

AB  - The induced deposition of W in the presence of iron-group metals has been known for a long time without a proper understanding of the mechanism of codeposition. Hints were made by several authors, concerning primarily a similar case of codeposition of Mo, which were not sufficiently substantiated by proper kinetic investigation as the research was oriented mainly toward practical aims. In the present investigation induced deposition of W with Ni was studied primarily from the point of view of the composition and phase structure of the resulting Ni-W alloy. The method of anodic linear sweep voltammetry was used to analyze deposits obtained at a rotating disc electrode, as it was proven to be a good tool for analysis of thin-layered deposits. 
	The polarisation diagram was found to exhibit a sharp current maximum and a subsequent decay at potentials at which Ni deposition starts. As some W oxide is found to deposit at less negative potential the sharp rise of current and the maximum are ascribed to catalytic effect of the oxide for hydrogen evolution, larger than that of depositing Ni-W alloy. 
	The deposit was found to exhibit two peaks upon anodic dissolution, both at significantly more positive potentials than that of Ni dissolution. The first peak is of limited quantity of electricity independent of the amount of the deposit, the  increase of the latter being reflected in the second peak only. 
	An aging effect was found rendering an alloy requiring much more positive potentials for dissolution than those for dissolution of freshly deposited alloys.
AB  - Taloženje volframa u prisustvu metala grupe gvožđa, indukovano taloženje, je fenomemen koji je odavno poznat. Međutim, mehanizam kodepozicije nije razjašnjen. Dosadašnja istraživanja indukovanog taloženja ( i to najčešće molibdena ) prvenstveno su bila usmerena ka primeni u praksi, a nedovoljno praćena odgovarajućim kinetičkim ispitivanjima. U ovom radu ispitivano je indukovano taloženje W sa Ni prvenstveno sa stanovišta sastava i fazne strukture dobijenih Ni-W legura. Metoda anodne linearne promene potencijala (ALSV) upotrebljena je za analizu prevlaka dobijenih na rotirajućoj disk elektrodi. 
	Na katodnim polarizacionim dijagramima taloženja nađen je oštar strujni maksimum na potencijalu koji odgovara početku taloženja Ni. Pad struje se može pripisati sporijem izdvajanju vodonika na leguri Ni-W, nego na oksidu volframa koji je se dobija pri manje negativnim potencijalima. 
	Na anodnim voltamogamima rastvaranja javljaju se dva karakteristična strujna vrha, oba na potencijalima znatno pozitivnijim od onih koji odgovaraju rastvaranju čistog Ni. Količina naelektrisanja koja odgovara prvom strujnom vrhu je ograničena odnosno, povećanje količine naelektrisanja pri taloženju odražava se u odgovarajućem porastu naelektrisanja drugog anodnog strujnog vrha.
