Cheng Haibin, +2 more
TLDR
A plating liquid for chemically plating the magnetic NiCoW film on the surface of NiTi alloy is an aqueous solution containing nickel sulfate, cobalt sulfate and ammonium sulfate as discussed by the authors.
Abstract: 
A plating liquid for chemically plating the magnetic NiCoW film on the surface of NiTi alloy is an aqueous solution containing nickel sulfate, cobalt sulfate, sodium tungstate, sodium hypophosphite, sodium citrate and ammonium sulfate. Its chemical plating process includes such steps as alkali washing of said surface of NiTi alloy, acid washing, sensitizing, activating, immersing it in said plating liquid and chemical plating. The plated product can be used as the medical magnetic scaffold for physiotherapy and chemicotherapy.
