Selective Plating for Prebraze

WHY USE SELECTIVE PLATING FOR PREBRAZE

While you may be using cadmium for AOG repairs, other brush plating applications, such as nickel prebrazing, can be used throughout the OEM process.

SIFCO ASC works closely with you to offer practical, cost-effective options for the surface enhancement of your OEM and MRO components. The SIFCO Process® Solutions used for prebrazing include AeroNikl® 250 and Nickel Acid Code 2080.

Selective Plating for Prebraze

REV 10/16

Increased Brazeability

Selective plating for prebraze creates an atomic bond between the nickel deposit and the base metal providing excellent wettability

and increasing the brazeability of the component.

Meets Major Specifications

Selective plating for prebraze meets aerospace specifications AMS 2403, 2424, and 2451 and is approved by Pratt & Whitney,

Rolls Royce and others.

Adaptable to Component Shape and Size

Selective plating, whether manual or automated, is not limited by the part size or shape.

Zero Risk of Heat or Part Distortion

Selective plating is performed at room temperature, creating no risk of part distortion from extreme temperatures.

Approved for Nickel Superalloys

Selective plating is the preferred method for the prebraze of Renes and Inconels.

Automated Process

With an automated process, variances are reduced, increasing quality outcomes and traceability. Technicians are also spared the

ergonomic risk associated with the maintaining the anode-to-cathode movement.

BENEFITS OF SELECTIVE PLATING

Issue SIFCO Process® Shot Blasting

WettabilityLower wetting angles provide excellent brazing filler metal

spreading and shortened brazing time.

Shot blasting results in greater wetting angles

resulting in less efficient brazing filler metal

spreading, increasing brazing time.

Adhesion

The SIFCO Process® creates an atomic bond and provides

excellent adhesion on all metals. Adhesion is not compromised

by severe, cyclical temperature fluctuations or by sharp, direct

impact.

Shot blasting prior to brazing, while increasing

fatigue stength, creates a mechanical bond.

FlexibilitySelective plating can be used on a wide variety of shapes and

sizes of parts; including holes as small as 1/4” in diameter.

Shot blasting is typically limited to line-of-sight

applications.

Risk of Part

DistortionNone.

Shot blasting poses a risk of distorting shape

and dimension depending on the size of the

component.

PortabilityThe SIFCO Process® is a portable plating process that can be

used in the shop or on-site.Limited to the shop or facility.
