Study of Parameters and Techniques for Chromium-electrodeposited Texturing

The textured rollers produced by the conventional techniques have some disadvantage performances that include rapid roughness attenuation, limited use time and more pits on roller surface, which are not suitable for the formation of roughness on the cold roller surface.In order to increase the service life of the textured roller, a technique process was designed to electroplate chrome on the IF steel surface.The experiment of DC superimposed pulse was performed to obtain the certain roughness chrome textured and hemisphere-shaped chrome coatings.From the results, it was shown that the roughness and hardness of coating obtained by electroplating was 3.79 μm at 850 mA/cm² and 1 000 HV respectively.
