Purpose

This specification covers the requirements for brush plating of zinc-nickel by electrodeposition.

Application

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.

Classification

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.
