Chrome plated rod surface defects

Dear All,

I am finding difficulty in understanding the chrome rod surface defect. I checked the chrome thickness it's 50 microns. The surface is having many pin holes with rusty marks.
I don't understand what could be the root cause for this.

Could somebody help me to understand the defect caused on the piston rod surface?

your cleaning is not proper.
check surface of rod before plating.Do the water break test.

You may have a lot of suspended solids in the chrome tank, especially if you use agitation.

You can use an porous pot and dummy the solution so that if it have any impurity can be removed.
