plating type


nickel plating


Electrodeposited nickel, using electricity as part of the deposition process, has a wide range of applications ranging from cosmetic to specific engineering applications. Nickel may be plated on iron, copper, or zinc alloys as a protective coating from corrosive attack in a variety of atmospheres. In the case of marine and aerospace applications, itscorrosion protection properties is typically dependent on the thickness of the nickel deposit, and in most cases, is used as an underplate barrier layer for gold or other precious metal deposits. Nickel plating intended for engineering purposes may be used for wear and abrasion resistance, but primarily serves as corrosion protection of parts. Heavy deposits of the plating may be used for additional protection against corrosive chemical environments, or as a means of building up the size of undersized or worn parts, where the deposit thickness is plated to meet a dimension rather than a specific thickness range.


specifications

AMS QQ-N-290 Nickel Plating (Electrodeposited)


classes:


  1. Corrosion protective plating*
  2. Engineering plating


Class-1 Processing Grades:


SB Single layer coating in a fully bright finish.

SD Single layer coating in a dull or semi-bright finish, containing < 0.005 percent sulfur and having an elongation greater than 8%.

M Multilayer coating, either double-layer or triple-layer.


*Corrosion Protection Grades


Corrosion protective abilities of Class 1 plating is dependent upon the thicknesses grade specified for the type of part being plated. For example, zinc and ferrous based materials require thicknesses grades F or greater, whereas copper based parts require grades G or greater in order to provide corrosion protective


Thickness Grades:


A 0.0016"

B 0.0012"
