Purpose This specification covers the engineering requirements for electrodeposition of a hard nickel and the properties of the deposit. Application This process has been used typically to provide good wear resistance to metal parts which may operate in service up to 450 ??(232 ??@ but usage is not limited to such applications. Diffusion heat treatment of the deposit is not required. 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.
