“…The arrangements of surface atoms are closely relate to many surface phenomena, such as adsorption, corrosion, oxidation, vacancy, catalysis, crystal growth and reconstruction [1][2][3][4][5][6][7]. In most cases, the causes of reconstruction are due to addition [8,9], removal [10,11] or displacement [12] of surface atoms.…”

With modified embedded-atom method (MEAM), the surface energies of the perfect and (1×2) missing row structure on (100), (110) and (111) surfaces, and (1×3), (1×4) and (1×5) missing row structure on (110) surface have been calculated for ten FCC metals Pb, Au, Pt, Ir, Ag, Pd, Rh, Cu, Ni and Al. According to the energy minimization, we know that the (1×2) missing row reconstruction cannot be formed spontaneously on (100) and (111) surfaces of all ten FCC metals. However, not only (1×2) but also (1×3) missing row reconstruction can be formed on (110) surface of Au, Pt and Al spontaneously. These are consistent with the experimental results except Al for which the experiment has not been reported. The results are also analyzed in terms of the surface configurations and valence electron structures.

“…Over the past few years, metal coatings, especially metal matrix composite coatings containing nano-particles which exhibit excellent properties including higher wear and corrosion resistance, higher hardness, more excellent self-lubricating in comparison with single metal coatings have been more widely studied. With the review and analysis of recent literature on composite electrodeposition, it can be found that many research efforts with Al 2 O 3 , SiC, ZrO 2 , TiO 2 and SiO 2 as the additive particles and with mild steel, stainless steel, copper, aluminium as the substrate have been widely reported [10][11][12][13][14][15][16][17][18][19][20]. However, pulse composite electrodeposition on sintered NdFeB permanent magnet, which is well known * Corresponding author.…”

“…The higher the H value, the lower the erosion rate. As demonstrated in our previous work [22], the hardness of composite alloying layer A (HV330) was higher than that of single Ni-based alloying layer (HV202). The highly dispersed nano-SiO 2 particles not only can prevent from dislocation movements, enhancing deformation-hardening capability of composite alloying layer, but also alleviate the impingement of sand particles by screening effect.…”

“…By comprehensive consideration of design principle concerning wear resistance alloy and corrosion resistance alloy, the authors put forward that the nano-particles reinforced Ni-based alloying layer is possible one of erosion-corrosion resistant candidate materials. The novel duplex surface treatment had been adopted to improve the corrosion resistance of composite alloying layer formed on the 316L stainless steel [22,23]. This duplex surface treatment technology provides a feasible route to fabricate particulate reinforced metal matrix composite coating, and opens new possibilities for enhancing wear resistance of Ni-based alloying layer without compromising of its corrosion resistance.…”

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.
