:Materials used as fuel cell electrode should be light, high conductive, high surface area for reaction, catalytic surface and uniformity of porous structure. Nickel is widely used in electrode materials because it itself has catalytic properties. When used as electrode materials, nickel of only a few ìm on the surface may be sufficient to conduct the catalytic role. To manufacture the nickel with porous structure, Electroless nickel plating on carbon fiber be conducted. Because electroless nickel plating is possible to do uniform coating on the surface of substrate with complex shape. Acidic bath and alkaline bathe were used in electroless nickel plating bath, and pH and temperature of bath were controlled. The rate of electroless plating in alkaline bath was faster than that in acidic bath. As increasing pH and temperature, the rate of electrolee plating was increased. The content of phosphorous in nickel deposit was higher in acidic bath than that in alkaline bath. As a result, the uniform nickel deposit on porous carbon fiber was conducted.

“…Electrochemical measurements in 3.5% NaCl showed that the corrosion potentials (E corr vs SCE) of the AZ31 alloy and copper coated samples are -1569 mV and -1368 mV, respectively. Electroless nickel-phosphorus layers were also deposited on AZ31 alloy coated with an organic interlayer of about 50 µm (Zhao et al, 2007b(Zhao et al, , 2008(Zhao et al, , and 2010. In a study the activation of the organic layer was carried out by means of palladium salts.…”

“…In general, the introduction of an intermediate layer (or interlayer) between the Mg substrate and the electroless Ni coat has the advantage of isolating the substrate from the Ni-P film, therefore improving the corrosion resistance [53]. The intermediate layers that will be presented in the following, include mainly an organic layer, a zinc phosphate layer, a copper layer and a zinc transition layer, which are all followed by electroless Ni plating.…”

“…Pre-treatment using zinc immersion was previously presented by Gray and Luan [9] and had the disadvantages of the need of a precise control to ensure adequate adhesion, for the use of a copper strike which attacks the zinc layer and the Mg substrate and for environmental reasons. The conventional zinc immersion procedure [53] …”

Magnesium alloys are attractive alloys in industrial applications , where light weight and good strength structures are required. Magnesium alloys are versatile and include both cast and wrought alloys. However, they have a drawback as they are prone to corrosion especially in harsh environments. For this reason, surface treatment of magnesium alloys is of prime importance for improving their corrosion characteristics.In the present paper, a survey of the different methods for surface treatment of magnesium alloys is presented and discussed. This is followed by a review of the recent work on electroless Ni plating technique with zinc pre-treatment applied on several magnesium alloys and the effect of pretreatment and post heat treatment on the coat characteristics. The surface morphology, surface roughness, thickness of the layer, EDX analysis, adhesion, hardness and corrosion resistance are covered in this review.
