AMS-2422 specs
Gold Electroplating

What is AMS 2422 | Gold Electroplating? 

When working with our clients in the Aerospace Engineering and Manufacturing industry, perfect compliance is needed to ensure the best surface finishing results possible.  

AMS 2422 is one of the Aerospace Engineering industry standard specs for gold electroplating. The specification only requires a minimum of 99.0% gold purity and desired thickness must be indicated on the purchase order.  

Benefits of AMS 2422 - Gold Electroplating 

  • Corrosion Resistance  
  • Abrasion Resistance  
  • Conductivity 
  • Aesthetic Appeal
  • Long Lasting Finish  
  • Increased Strength  
  • And more!  

AMS 2422 Technical Specs

Purchase order shall specify not less than the following

  • AMS2422F

  • Plating thickness desired

  • Minimum thickness on internal surfaces, if required

  • Basis metal to be plated

  • Tensile strength or hardness of the basis metal (this would not apply to Aluminum)

  • Pre-plate stress relief to be performed by plating processor (time and temperature) if different from 3.1.2

  • Special features, geometry or processing present on parts that requires special attention by the plating processor

  • Hydrogen embrittlement relief to be performed by plating processor (parameters or reference document) if different from 3.3

  • Solderability when required

  • Quantity of pieces to be plated

Copper Strike

Standard parts are to be plated with either a copper flash or copper strike, unless parts are made of copper/copper alloy containing less than 15% zinc. If these criteria are met, the strike can be omitted.

  • Minimum thickness of 0.0001 inch (2.5 um)

  • Nickel Strike is to be done after copper strike

  • Minimum thickness of 0.0001 inch (2.5 um)

  • Gold plating done after nickel strike

  • Minimum thickness of 0.00005 inch (1.27 um) on all surfaces on which gold plating is specified

Electroplating

Electroplating

Electroplating is a process by which one metal is deposited onto a base metal (substrate). These deposited metals offer a variety of benefits including thermal and electrical conductivity, corrosion resistance and more. AOTCO electroplates a wide variety of both standard and exotic metals.

Anodizing

Anodizing

Sometimes called a “conversion coating” Anodizing is an electrolytic process in which an oxide (anodic) layer is chemically built on the surface of the substrate material, providing anti-corrosion and other benefits. AOTCO offers, Type I, Type 2, Type 3 and Titanium anodizing services.

Passivation

Passivation

Passivation is a term for a variety if processes that make a metal (most commonly stainless steel) or other substance unreactive, or passive, by altering the surface layer or coating the surface with a thin inert layer. AOTCO performs both citric and black oxide passivation techniques to a range of specifications.
