Ni/TiC NANOKOMPOZİTLERİN BİR KATYONİK DİSPERSANT EŞLİĞİNDE ELEKTRODEPOZİSYON MODELİ
Modeling the Electrodeposition of Ni/TiC Nanocomposites in the Presence of a Cationic Dispersant

Damla EROĞLU PALA [1]


Ni/TiC nanokompozitlerin elektrodepozisyonu dönen disk elektrot sisteminde, bir katyonik dispersant eşliğinde modellenmiştir. Önerilen mekanizmada, bir TiC nanoparçacık difüzyon tabakası boyunca taşınır, elektrot yüzeyine adsorplanır ve yüzeydeki rezidans süresi büyüyen nikel depozite gömülme süresini geçtiğinde filme inkorpore olur. Dolayısıyla TiC inkorporasyon hızı, parçacığın yüzeydeki rezidans süresi ve yüzeydeki parçacık miktarıyla doğru, parçacığın gömülme süresiyle ise ters orantılı olarak tanımlanmıştır. Modelde rezidans ve gömülme süreleri ise akım yoğunluğu, hidrodinamik koşullar, parçacık boyutu ve dispersant konsantrasyonuna bağlı olarak ifade edilmiştir. Buna istinaden, TiC inkorporasyon hızı ve depozitteki TiC hacim%, dispersant ve TiC elektrolit konsantrasyonları, akım yoğunluğu ve elektrot dönme hızına bağlı olarak öngörülmüştür. Elektrolite eklenen katyonik dispersantın depozitteki TiC miktarını arttırması ise dispersantın TiC nanoparçacıkların yüzeydeki rezidans sürelerini arttırması ile açıklanmıştır. 

The electrodeposition of Ni/TiC nanocomposites on a rotating disk electrode in the presence of a cationic dispersant is modeled. In the proposed mechanism, TiC nanoparticles are transported through the diffusion layer, adsorbed on the electrode surface and incorporated into the growing nickel film if the residence time a particle on the surface exceeds the burial time. Therefore, TiC incorporation rate is proportional to the residence time and the total number of particles on the surface, whereas it is inversely proportional to the burial time. In the model, residence and burial times of a particle are defined as a function of the current density, hydrodynamics, particle size and dispersant concentration. And so, TiC incorporation rate and TiC vol% in the deposit are predicted as a function of TiC and dispersant electrolyte concentrations, current density, and electrode rotation speed. The model proposes that the addition of the dispersant increases the TiC amount in the deposit through increasing the residence time of a particle.
