"Brush Plating"
"Brush Plating"
(OP)
Greetings to all!!!
I am working on a project requiring a 3" bore to be refurbished in a localized area (approx 2" long encompassing the bore. The customer is wanting to "brush plate" the bore and then re-polish the surface. I am not familure with with process. I have found a few web-sites but I am still left with some questions.
1) How thick is a typical application?
2) Does a thicker or thinner application adversely affect the properties of the application?
3) Is this process typically used as a tempory fix or is it considered permanent?
4) How does the process stand up to cyclic operations @3000 psig with the piston seals contacting the refurbished surface?
5) Is the plating prone to flaking off?
6) If a scratch is developed, will the scratch propagate within the plating surface and cause flaking.
I know that some of the questions will are specific for my application. However, I am trying to find out if anyone else has experience with this type of electroplating. If so, is this generally acceptable as an alternative to welding and re-finishing the bore.
Thanks for any info.

OK as long as you don't need a totally smooth surface [ends up with flats & grooves - good for holding glue/oil or press fit.]

The better methods that I've used is skin the whole cylinder and plate the entire bore or if real bad bore the entire cylinder oversize, plate with iron and then Hard Chrome Plate or undercut the bore and reweld the entire length and remachine.
