Help repairing chrome rods


 

I am looking for a process that I've read about in Heavy Equipment trade journals where I can repair chips and nicks in the chrome of hydraulic cylinder rods in our shop without having to send the rods out for repair. These rods are subjected to extreme work conditions, so whatever I use must be tough.

Hello Steve!

You want to go to the "search products" function of this website, and type in "selective plating". Then you'll find the vendors that advertise here who offer brush plating units, which will do just what you want. Realize that you will need to have a plan for waste disposal, and that safety will also need to be addresses as you'll be playing with some aggressive chemicals. But the vendors listed know their stuff, and can get you going pretty easily.

Good luck!

Hi Steve,

We repair chrome plated piston rod in our hydraulic shop. It is relatively simple, with practice and care you can get very good at it. First, tig weld a stringer bead along the entire scratch or groove length. Then using a convex grinding fixture assembly grind as close as possible and then use a pneumatic hand grinder with scotch brite to lap and blend the weld into the chrome surface. It takes some practice to get good at it.
Good Luck.
