The PVD coating service we offer is specific for firearms applications. It adds an ultra thin (semi-tough) surface finish to the substrate. Friction coefficient and corrosion resistance is greatly improved. Most surfaces do not need masking unless tolerances between the mating surfaces are extremely tight. Blue PVD is not as wear-resistant as TiN (titanium nitride) coating and could wear quickly in high contact areas such as barrels and slides. Blue PVD is also sensitive to fingerprints and oils. Exact blue coloring will vary. Color will transition from Blue, Purple, Bronze, Gold. Thickness is approximately 1-5 microns (.00004"-.0002").
AN INCONSPICUOUS AREA MAY BE LEFT UNCOATED FOR FIXTURING PURPOSES.
