SermeTel Process 5380 DP (Dense Pack) consists of a closely packed aluminum-filled chromate/phosphate basecoat, sealed with a chemically inert chromate phosphate topcoat. The coating provides excellent protection to stainless steel and ferrous alloys, and will operate at temperatures up to 1200°F (650°C).

Advantages

Process 5380 DP should be used on any component where serious concerns are corrosion/erosion protection, tight tolerances, surface finish, or where the potential for media entrapment is possible due to part configuration. On dimensionally critical surfaces, precision coating thicknesses of as thin as 0.3 mils (7.5 µm) can be achieved.

Applications

The aerodynamic finish of Process 5380 DP makes it ideal for any gas path turbine component, such as compressor blades, vane and shroud assemblies, and diffusers. Similar SermeTel topcoated systems have seen millions of hours of successful service in military, commercial aviation and industrial turbines.
