Method for improving plating quality of chrome-plated piston rod surface
Jul 11, 2018

The surface of the finished chrome-plated piston rod will be coated with a thick layer of chrome plating. Usually, the thickness of this protective layer is above 20μm. This layer of chrome plating can improve the hardness, wear resistance, temperature resistance and corrosion resistance of the chrome-plated piston rod. Since the chrome plating process on the surface of the piston rod is not a simple matter, in the actual operation, suitable measures are needed to improve the plating quality of the surface.

 

First, the uniformity of the chrome-plated piston rod affects the quality of the plating during the electroplating process. In general, the uniformity of the piston rod can adjust the density of the anode cloth according to the size of the hydrogen bubbles ejected from the cathode of the piston rod. Because this can make the hydrogen bubbles escape evenly, so that the plating thickness on the piston rod is uniform.

 

In addition, the plating process requirements for the surface of the chrome-plated piston rod are relatively strict during the processing. It is therefore necessary to ensure that the components of the fixture are large enough to withstand the high currents in the plating process. Moreover, we must also keep the contact points of the fixture clean, firm and closed, which helps to ensure the quality of hard chrome plating on the surface of the chrome-plated piston rod.
