Hard chrome plating needs microscopic bubbles

April 19, 2010

Sir,

We are manufacturer of bearings and we are doing hard chrome plating.
Our product doesn't performs equal to our competitor product.
So we have analyzed chrome surface of ours and competitor in high magnification(700X).
We found some bubbles visible in the competitors hard chrome surface which is not present in our hard chrome surface.

(Note: For better understanding Bubbles seems like small water droplets)

What might be the bubbles visible in competitor hard chrome plating surface.

What should we do in our hard chrome plating process to get the same.

How can I attach the comparative photos here for your reference.

Your favorable reply will be helpful.

Thanks & regards
