“…Since pits initiate at secondary particles within the matrix, composites have more pit initiation sites than monolithic matrix [18]. Similarly, improvement in corrosion resistance has been declared with decreasing volume fraction of Al 2 O 3 particle in Al -4 wt.% Mg alloy matrix composites [28]. However, Kiourtsidis and Skolianos [22] explained the progress of corrosion by two anodic reactions, namely, corrosion of the a-phase adjacent to intermetallic regions and pitting of the dendrite cores, instead of galvanic corrosion developed between the reinforcing particles and the matrix.…”

“…Several corrosion studies on the Al matrix composites showed that composites have more pit initiation sites than monolithic matrix, and the presence of a reaction product at the interface might act as an effective cathode which would increase the cathode to anode ratio promoting higher localized corrosion [19][20][21]. By using transmission electron microscopy (TEM), salt spray test and potentiodynamic measurements, Erler et al have investigated interface behavior in nickel composite coatings with nano-particles of oxide ceramic.…”

“…However, it is worth noting that there is a serious disagreement among researchers on the corrosion characteristic of metal matrix composites. Several corrosion studies on the Al matrix composites showed that composites have more pit initiation sites than monolithic matrix, and the presence of a reaction product at the interface might act as an effective cathode, which would increase the cathode to anode ratio promoting higher localized corrosion [34,35]. Lampke et al [36] have detailed investigated the incorporated ceramic particles on the corrosion behaviors of Ni-based composite plating coating.…”

In order to improve the corrosion and erosion-corrosion resistance of 316L stainless steel in engineering application, two kinds of composite alloying layers were prepared by a duplex treatment, consisting of Ni/nano-SiC and Ni/nano-SiO 2 predeposited by brush plating, respectively, and a subsequent surface alloying with Ni-Cr-Mo-Cu by double glow process. Potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) were performed on the two kinds of composite alloying layer using 10 wt% HCl solution to assess the corrosion behavior. Erosion-corrosion tests were carried out by erosion-corrosion test rig in acidic flow and acidic slurry flow for test time of 20 h at four different rotational speeds. Results of electrochemical tests indicated that the corrosion resistance of composite alloying layer with brush plating Ni/nano-SiO 2 particles interlayer approximated to that of single Ni-based alloying layer, whereas the corrosion resistance of the composite alloying layer with brush plating Ni/nano-SiC particles interlayer was apparently inferior to that of Ni-based alloying layer in 10 wt% HCl solution at static state. Under the conditions of acidic flow and acidic slurry flow, the mass losses of tested samples increased with increase in the time of erosion-corrosion tests and the rotational speeds of samples. The mass losses of composite alloying layer with brush plating Ni/nano-SiO 2 particles interlayer were lower than that of single Ni-based alloying layer at all rotational speeds, except at 1.88 m/s in acidic flow. The mass losses of composite alloying layer with brush plating Ni/nano-SiC particles interlayer were higher than that of single Ni-based alloying layer at all rotational speeds, but were obviously lower than that of AISI 316L stainless steel. The influences of second phase on the corrosion and erosion-corrosion of the two kinds of composite alloying layer were discussed in this paper.
