With 16 types of electroplating baths and processes most commonly used in industry, including 3 Zn platings, 4 Cu, 5 Ni and 2 Sn platings as well as 2 Au imitation, current distribution regularities on cathode in Hull cell were reinvestigated by measuring c.

Effects of five common metallic impurities in high speed sulphate bath on appearance of Zn deposit has been investigated by Hull cell experiment, among which those ions of Ag, Pb and Cu are obvious.

The influences of addition agent XHG-01A, brightening agent XHG-01B ,main salts and complex agent are discussed by means of Hull Cell test and the properties of plating solution and plating layer are also tested.

A new process of high stable acidic bright Sn electroplating, which led to grain refinement, high stability, leveling and bright appearance, was developed by Hull cell tests.

In order to obtain better semi-bright nickel coating,a new process was studied based on the selection of additive agents for semi-bright nickel electroplating solution with hull cell tests.
