Plating, Brush, Zinc-Nickel Low Hydrogen Embrittlement
|Publication Date:||1 August 2018|
This specification covers the requirements for brush plating of zinc-nickel by electrodeposition.
This process has been used typically to improve corrosion resistance of steel parts operating under 500 °F (260 °C) as-plated or under 250 °F (121 °C) when chromate treated, to repair zinc-nickel deposits and to repair damaged or worn parts, but usage is not limited to such applications.
Type 1 - As-plated
Type 2 - As plated with supplementary surface treatment
Grade A - Hexavalent chromate treatment
Grade B - Trivalent chromium treatment
Unless a specific type is specified, Type 1 shall be supplied.
Unless a specific grade is specified, either may be supplied.
Safety - Hazardous Materials
Shall be in accordance with AMS2451.
