Electrolytic Nickel Plating In Canada

Nickel Plating in Canada in accordance with QQ-N-290 / AMS-QQ-N-290, AMS 2403 & ASTM B689

LAYERS
SB – Single layer (bright)

SD – Single layer (dull)

M – Multi layer

When plated on steel, this process requires a duplex nickel process with careful control of the sulfur content. This multi-layer plating has been shown to increase corrosion resistance over a single plating material of the same thickness. The specification can be met with either a Watts or a sulfamate bath, but the properties of the deposit (e.g. internal stress, brightness, corrosion resistance) are different for these two types of plating. A Watts bath uses nickel sulfate as the metal salt, while the sulfamate bath uses nickel sulfamate. Example order: Nickel Plate per QQ-290 Class 1 Watts Bath, or AMS 2403 Class 2 Sulfamate Bath.

AMS 2403
This process has been used typically to provide moderate corrosion and oxidation resistance to metal parts but without control of other characteristics and for the buildup of surfaces. Plating thickness shall be specified in the contract, purchase order or drawing.
ASTM B689
Types
1
Nickel electroplated from solutions not containing hardeners, brighteners, or stress control additives.
2
Nickel electrodeposits used at moderate temperatures and containing sulfur or other codeposited elements or compounds that are present to increase the hardness, to refine the grain structure, or to control the internal stress of the electrodeposited Nickel.
