The surface is
part of the
spec.
A part is only finished when its surface does what the print requires: resist wear, shed corrosion, lower friction, or hold a coating. We engineer the finish to a controlled spec and verify the part against it, in-house, alongside the machining.
Low friction, high wear resistance.
Nickel boron (NiB) lays down a hard, uniform, low-friction surface that holds up under wear and cycling. It coats complex geometry evenly, including bores and internal features, without the build-up and masking headaches of harder line-of-sight processes. A strong alternative where hard chrome used to be the default.
Hardness, corrosion resistance, and a uniform black finish.
Black Nitro Met (salt-bath nitride) diffuses nitrogen into the surface for a hard, fatigue-resistant case with strong corrosion resistance and a clean black finish. We account for the dimensional growth the process adds, so the part still measures in-spec when it comes back to the CMM.
Tell us what the surface has to do.
Wear life, corrosion exposure, friction and lubricity, electrical or vacuum requirements, cosmetic finish, and how much dimensional growth the part can tolerate. We will recommend a process, hold it to a spec, and document the result. When a job calls for a process we do not run in-house, we route it to a vetted partner under the same quality discipline.
Measured before and after.
Finishing happens next to our metrology lab, so critical dimensions are checked before and after the surface treatment. The finish improves the part; it does not put it out of tolerance.
