Sulfamate nickel plating: put material back on worn parts

Before you scrap a shaft, bore or housing, ask whether the material can be put back. Sulfamate nickel builds thickness on worn and undersize parts with low internal stress and no welding heat. We then grind it back to size and, where the part needs a hard wear surface, cap it with hard chrome.

When sulfamate nickel makes sense

• Shafts ground undersize one too many times
• Bearing fits and seal areas worn past the repair limit
• ID bores on cylinders and housings
• Parts where weld heat could distort the part or change the base metal
• An underlayer before hard chrome, to seal the base metal and give the chrome a sound surface

How we do it

1. Inspect and measure the part against the drawing.
2. Strip old coatings and prepare the surface.
3. Plate sulfamate nickel to build the material back.
4. Grind or hone back to your print.
5. Add hard chrome on top where the part needs wear resistance.
6. Final inspection, with liquid penetrant testing when required.

Why H&M Plating

Nickel, chrome, HVOF and precision grinding under one roof means one PO and no shipping between vendors. Our ISO 9001:2015 shop in Houston has been rebuilding parts since 1971, and we take work from across the US.

Frequently asked questions

Should I use nickel or weld overlay?

Weld rebuilds almost anything, but the heat can warp precision parts. Sulfamate nickel goes on at low temperature. We’ll tell you which fits your part.

How thick can you build with nickel?

It depends on the part, the base metal and how it is used. Send the drawing and current dimensions and we will tell you what is possible.

Can every worn part be saved?

No. Cracks, fatigue damage and heavy pitting can make replacement the right call, and we will tell you so.
