![]() ![]() If you have any safety questions, check with your company’s safety officer.ĩ. You’ll also need to keep a pair of lab tongs handy. This should include gloves, goggles and a lab coat. ![]() It is important to wear the proper personal protective equipment. ![]() To remove this protective coating a 50 percent solution of hydrochloric acid is used to strip the zinc coating prior to plating.Ĩ. In the case of the zinc coated panel, the zinc is there to protect the panel from rusting and excess scratching. In our evaluation we will be using a zinc coated steel panel.ħ. The cathode or hull cell panel is typically zinc coated steel. Alligator clips are easy connections from the rectifier to the anode and the cathode.Ħ. Here color coded cables to connect the rectifier to the hull cell. Appropriate Clamps and leads are also necessary. A rectifier that has DC voltage output of 0 to 10 Volts and amperage output of 0 to 10 amps is preferred.ĥ. This unit is a single source control for voltage. A laboratory grade DC Power source/rectifier with variable control in necessary some laboratory units have control for both amperage and voltage. Obviously we need a plating solution: as we previously mentioned we are using acid zinc electroplating solution.Ĥ. Today we are evaluating an acid zinc solution so we will be using a zinc anode.ģ. There is a specific anode required for each plating process. A hull cell anode: this needs to correspond to the plating bath to be evaluated. Hull cells may come in a variety of sizes, but the 267 milliliter is the most common.Ģ. The hull cell test or analysis is designed to analyze the deposit appearance and deposit characteristics of a specific electroplating solution. This video will show you how to run a hull cell.ġ. An evaluation of the deposit on the cathode across a range of current densities is useful in demonstrating the capabilities of a plating bath solution. A hull cell is a testing tool, or a miniature electroplating cell, in which an electroplating solution is evaluated across the range of operating conditions. ![]()
