The limiting current density of the stack without fan is very less (i.
The limiting current density of the stack in induced draught mode and forced draught mode is 152 mA [cm.
2], the limiting current density is higher than 3 & 4 kgf/[cm.
The reason for this is that metal ions cannot be reacted faster than they can arrive at the cathode surface, which is called the limiting current density.
2] have declared that the IJE both enables a fast deposition rate because of a rise in the limiting current density and provides the volume fraction control of particles by changing the jet velocity.
In the electroplating studies using with impinging jets, the mathematical relation between Jet nozul velocity (Vj) and the limiting current density (IL) can be calculated the correlation (Eq.
So, in this study the value of limiting current density was determined experimentally.
In the beginning of the study, the relationship between jet velocity (Vj) and limiting current density (iL) was determined in terms of Vj.
The effect of jet velocity on limiting current density in Ni jet electroplating is shown in Fig.
The relationship between the limiting current density (iL) and dimensionless nozul to plate distance (H/d) is shown as a function of (H/d) in the Ni jet electroplating in Fig.
However, the limiting current density values was increased as increased nozul flow rates, though the applied voltage between anode and cathode is constant (Fig.
This situation was explained with dimensionless limiting current density, N, in the literature [11].
