Plating, Nickel-Cadmium Diffused
|Publication Date:||1 June 2018|
This specification covers the requirements for an electrodeposit of cadmium diffused into an electrodeposit of nickel on carbon, low-alloy, and corrosion-resistant steels.
This coating has been used typically to prevent corrosion of carbon, low-alloy, and corrosion resistant steel parts that may operate in service up to 900 °F (482 °C), but usage is not limited to such applications. This process is not suitable for use on parts of complex shape where minimum nickel plate thickness requirements cannot be met and on parts whose hardness or strength would be reduced below drawing or specification requirements by heating to 640 °F (338 °C).
Safety - Hazardous Materials
While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sole responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved.
This document includes cadmium as a plating material. The use of cadmium has been restricted and/or banned for use in many countries due to environmental and health concerns. The user should consult with local officials on applicable health and environmental regulations regarding its use. Great care is necessary during this duplex plating process. Cadmium must only be plated directly onto the nickel plate, otherwise liquid cadmium metal embrittlement may occur in the base metal (see 8.6)
