The invention discloses a
phosphorus chemical
nickel plating concentrated solution and a plating process, the concentrated solution comprises three parts of an A solution, a B solution and a C solution, a main salt, a brightening agent, an accelerating agent and deionized water are mixed into the A solution at
room temperature; a first buffer, a first complexing agent,
sodium hypophosphite, a stabilizer,
polyethylene glycol 6000, a brightening agent and deionized water are mixed into the B solution at
room temperature; a second buffer, a second complexing agent, the stabilizer, the
sodium hypophosphite, the
polyethylene glycol 6000, the accelerating agent, the brightening agent,
ammonia and the deionized wate are mixed r at
room temperature into the C solution; the A solution and the B solution are used for grooving, and the A solution and the C solution are used for replenishment. According to the
volume percentage, the A solution, the B solution, and
dilution water are mixed into a chemical
nickel plating solution for plating, the
nickel content in the nickel plating solution is lower than 4.0g / L, and the A solution and the C solution are replenished. When the concentrated solution is used for nickel plating,
deposition rate is quick,
coating hardness and
wear resistance are high, and the concentrated solution is suitable for chemical nickel plating of aluminum
alloy, all kinds of iron
alloy,
copper alloy, nickel iron alloy,
nickel copper alloy and some non conductive substrates.
