  • Properties and applications of electroless nickel

    Electroless nickel plating is a process for depositing a nickel alloy from aqueous solutions onto a substrate without the use of electric current It differs, therefore, from electroplating which depends on an external source of direct current to reduce nickel ions in the electrolyte to nickel metal on the substrate Electroless nickel plating is a chemical process which reduces nickelElectroless nickel plating is used to deposit nickel without the use of an electric current Electroless nickelphosphorus (Ni–P) coating consists of an alloy of nickel and phosphorus The autocatalytic deposition process occurs in an aqueous solution with chemical reactions caused by the catalytic reduction of the nickel ion with sodium hypophosphite in acid baths TheElectroless Nickel an overview | ScienceDirect TopicsThe primary criteria for using electroless nickel generally falls within the following categories: 1) Corrosion resistance 2) Wear resistance 3) Hardness 4) Lubricity 5) Solderability and bondability 6) Uniformity of deposit regardless of geometries 7) Nonmagnetic properties of highphosphorus nickel alloy In the early years, platers encountered many problems withELECTROLESS NICKEL PLATING
