SAE AMS 2410K:2010-04-19

This specification covers the requirements for electrodeposited silver on other metals, usually with a nickel strike between the basis metal and the silver. Silver plating has been used typically to provide a bearing surface and to prevent galling or seizing of surfaces of parts made of corrosion-resistant steels and of parts made of other metals not deleteriously affected by high-temperature baking, but usage is not limited to such applications. Silver plating is the most commonly used coating for turbine engine fasteners providing an even degree of lubrication up to a maximum service temperature of about 1200 °F (650 °C).
