Aerospace – Typical Applications
- Pre-Braze – turbine blades, turbine vanes, turbine stators and frames are nickel plated to ensure proper wetting of the surfaces to be brazed. Compared to other methods of applying the intermediate nickel layer, selective brush plating, is faster, more consistent, and more cost effective.
- Surface enhancement – OEM applications use nickel or a nickel alloy to improve hardness and wear resistance of the component.
- Selective application of electroless nickel on shafts and other components. Encapsulated flow technologies allow for faster set-up and control of the process, lowering costs and turn-time.
- Application of sulfamate nickel plating on selected bores of landing gear. Using either encapsulated brush or CVGP™ plating technologies, the speed of setup and application provides significant cost and process control benefits versus tank and other “out-of-tank” methods.
- Corrosion Protection – Touch up coatings for corrosion protection with Cadmium and Zinc-Nickel LHE™ (low hydrogen embrittlement) allow repairs to be made on-site, in place, saving disassembly.
- Refurbishment – MRO applications use nickel or sulfamate nickel for dimensional restoration of an inside or outside diameter on the component.
- Anodizing – Repair applications replace worn or damaged hardcoat with a new, anodized hardcoat coating.

Plating Engineered Deposits Onto Ti 6-4 and 6-6-2
The SIFCO Process® enables you to selectively, brush plate adherent deposits onto Ti 6-4 and Ti-6-6-2 to improve the surface properties of localized areas on components for either OEM or repair applications.
This micrograph shows a Ti 6-4 base that is plated with 0.0014" thickness of SIFCO Process® nickel, followed by 0.0142" of copper, that is capped with 0.0023" of nickel. Brush plated deposits consistently meet the adhesion requirements of AMS 2451 and ASTM B 571 (bend test method), and no hydrogen embrittlement per GM 3661P.
With an adherent base layer of nickel, specific deposits to meet your engineering requirements can be selectively plated to a precise thickness.
Brush plated surface enhancements will enable you to improve:
-
Brazability
-
Corrosion Protection
-
Conductivity
-
Lubricity
-
Hardness
-
Wear Resistance

Co-Cr3C2 Metal Matrix Composite
SIFCO Applied Surface Concepts has developed a new Co-Cr3C2 metal matrix composite for high temperature applications. This deposit is selectively applied to localized areas on components for either OEM or repair applications.
 
SIFCO’s Co-Cr3C2 is an adherent, ductile, dense, non-porous deposit that provides high temperature oxidation protection with superior wear resistance that can be improved by heat treating. These micrographs show Cr3C2 particles, uniformly deposited in a 6 mil thick, machinable cobalt deposit. |
