Hull Cell Long-type is suitable for checking covering power in detail, so we chose Long-type. Of course standard Hull Cell can do strike nickel plating, but in this plating method, covering power is the focused point. I would like to perform strike nickel plating with Hull Cell. We apologise for inconvenience, but please make nickel-plated test pieces just before examination on your own. That is why we do not sell nickel-plated test pieces. It is because plated nickel film makes oxide film easily, and it gives influence to plating test results. Additionally, chromium plating bath tends to raise its temperature intensely, so please be careful. In case of hard chromium plating, iron plate can be a cathode, but in that case the iron cathode often be used with relatively higher current density, so it seems that total current should also be set relatively higher in range of 10A to 30A. But we recommend using brass cathode plate or nickel-plated cathode plate for decorative chromium plating. Can I use iron test piece as a cathode for chromium Hull Cell test?Ī. If the amount of chloride is much more, not only back side, but also low-current part of front side can be etched. If chloride is contaminated into plating bath, back side of brass plate is etched. What does it mean, “If brass plate is used as cathode for chromium plating, contamination of chloride can be inspected”?Ī. Please refer to procedure below.Įx.) How to hold filtering paper (diameter: 125mm) as anode bag In Hull Cell test, you can use filtering paper as anode bag. We used to have, but now they are discontinued. Platinum-plated Titanium for Tenori Hull Cell(31×31×t2mm)Ī. In that case, please contact us before your order. A table below is popular products, but there are other possible materials which can be produced as special order products. We have not only copper and brass, which are widely used, but also other anodes and cathodes to match customers’ requirements. What kind of Hull Cell anodes and cathodes do you have?Ī.
