A-45WJ /A-45W HIGH SPEED PLATING HULL CELL TESTING KIT

A Hull cell tester that plating a round bar type test piece (φ8x100mm) while rotating it at high speed with a motor. A deposited film with a current density distribution for each stirring speed can be obtained on a single test piece. High-speed plating enables experiments with a current density closer to the actual site.
What you can see with High Speed Hull Cell
・The state of deposited film (bright, burnt, or dull) can be judged from its exterior appearance.
・The state of the influence caused by additives depending on agitation speed can be observed.
Usage Example
・Optimal anode position for a hoop line can be examined through administering control of agitation speed, electrical quantity, and electricity power-up speed.
・Also applicable for control of plating solutions in barrel plating and regular plating.

By using it in combination with the Agitation Effect Test Kit, which can examine the agitation effect at a constant current density, more multifaceted analysis can be performed. Most of the parts are shared, so please use the set (A-45WJ-T) that can analyze both.

Principle of Hull Cell Test for High Speed Plating ( HCHS )

Hull Cell Test kit for High Speed plating (HCHS) was specifically developed for the test of high speed plating by Yamamoto-MS. In HCHS, a cathode, rotational rod is used instead of a cathode plate in a standard Hull Cell. The structure of HCHS resembles a standard Hull Cell turned sideways into vertical position. This structure allows a very wide range of current density distribution to be obtained simultaneously on one cathode rod. Specifically, high current density is obtained at the region close to the anode and low current density is obtained at the region far from the anode.In HCHS, by rotating the cathode rod with a motor, high speed agitation, which is required in high speed plating, is achieved. For example, with a test piece with a 8mm diameter, if the test piece (cathode rod) is rotated at 40rpm, the agitation speed on the cathode surface becomes 1m/min. In the range of 10 ~ 3000 rpm, current density distribution on the cathode rod is uniform and independent to rotational speed, and given by the formula shown below:

[ Cathode current density distribution formula ]

Dk = I ( a – b log x )

Dk: cathode current density ( A/dm2 )
I: total current ( A )
a,b: constant determined by plating solution type and cathode current efficiency
xx: distance from tip of test-piece ( cm ) ( provided, 1cm ≦ x ≦ 9cm )
