New Technology Provides
Excellent Adhesion Of Nickel Onto   Titanium 6-4 and Titanium 6-6-2
 

Adherent nickel deposits

SIFCO Applied Surface Concepts has developed a process of selective brush plating adherent deposits onto Ti 6-4 and Ti 6-6-2 thereby improving the surface properties of localized areas on OEM aerospace components or component repair applications. 

Brush plated deposits with adhesion to AMS 2451 and ASTM B 571 (bend test method).

To optimize the adhesion of the deposit to titanium alloys this process removes titanium’s passive oxide and micro-roughening to increase surface area.  Brush plated deposits consistently meet the adhesion requirements of AMS 2451 and ASTM B 571 (bend test method), with no hydrogen embrittlement per GM 3661P.
 With an adherent base layer of nickel, many additional deposits can be selectively plated to a precise thickness for: 
• Preparation for Brazing …
Aerospace brazing is used on super alloy components used in aerospace applications, joining them together with filler metals containing melting point depressants such as boron and silicon. Aerospace brazing is done in high vacuum furnaces.
• Improved Wear Resistance for mechanical reliability
• Improved aircraft Corrosion Protection
• Better Lubricity …
High lubricity prevents galling where heat caused by friction causes one piece of metal to remove material from another, as well as reducing friction, which is critical in the function of machinery where metal surfaces touch one another.
• Increased Hardness which determines the material's resistance to deformation.
• Increased Conductivity
• Resizing & Refurbishing aerospace components
 
These additional deposits can range from soft and hard nickel deposits, to copper deposits, Nickel Preplate tin, and zinc, to silver, gold, and platinum deposits. 
 
Excellent adhesion is obtained without the use of hydrofluoric acid in the process, or heat treatment after plating.
