NiFe plating

FIGURE 26.25 Composition of a NiFe film plated on a rotating disk electrode as a function of the total plating current for different disk rotation speeds at 25°C. Solution composition was 0.2 M NiCl2, 0.4 M H3BO3, and 0.5 M NaCl (pH = 3). Data from [106]. (Reproduced by permission of ECS—The Electrochemical Society.)... 

Since 1995, consumer and industrial Ni/Cd battery recycling in the U.S. has been primarily done at the International Metals Reclamation Company, Inc. (INMETCO) using a process licensed from SAFT NIFE. The cadmium is distilled from the plates using a low temperature thermal process, and the material is used for new battery production. The nickel content of the battery goes into the standard INMETCO stainless steel remelt alloy production. In general, this thermal recovery process makes up the majority of the world recycling capacity. The cadmium is recovered and purified as the metal or can be converted to cadmium oxide.

In a similar implementation, an electromagnetic actuator was introduced in Judy and Muller (1996, 1997). This actuator consists of a torsional polysilicon beam, firmly fixed at both ends to the substrate, and an attached magnetic plate made of NiFe at the middle of the beam. When a magnetic field is applied by an electromagnet, a pure moment is induced and the magnetic plate is rotated out of plane (Figure 2.11). The electromagnet is actually a 10-turn coil...
