Safety measures for hard chrome plating on Hard chrome plated rods
Feb 18, 2019

On the finished piston rod, there is a thick chrome plating on the surface, and its thickness is generally above 20μm. This chrome plating can improve the hardness, wear resistance, temperature resistance, corrosion resistance, etc. of the piston rod. performance. But the chrome plating process on the Hard chrome plated rod surface is not a simple matter.

 

In the electroplating, the uniformity of the Hard chrome plated rod can adjust the density of the anode cloth hanging 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 order to prevent the discharge point or edge tip discharge, we should install a small cathode at 6mm-12mm from the power point. However, when loading, it is not possible to install a small cathode that exceeds the conductivity of the fixture. At the same time, the auxiliary cathode ring should be installed on both ends of the piston rod, and placed horizontally on the adjusting frame. The height can be adjusted by the nut on the adjusting frame. Then, it is horizontally hoisted into the long plating tank. At this time, one end of the plating tank should have a mechanism for clamping the piston rod, so that the Hard chrome plated rod can be clamped to the clamping mechanism by the nut screw of the outer end of the shaft. On the outer end.

 

The Hard chrome plated rod can be chrome-plated by horizontal rotation, and the electroplating circuit of the piston rod in the hard chrome plating process is changed to approximate the equivalent resistance circuit, so that the power line is approximately evenly distributed and the dispersion ability of the plating solution is improved.www.xhychromerod.com
