“…This is caused by the influence of rprecipitation inside interdendrites. The secondary r-phase was a (Cr, Mo)-rich phase and was demonstrated to be detrimental to corrosion resistance in SS for causing a (Cr, Mo)-depleted region and a stressed region around it [72][73][74][75][76][77]. The corrosion preference of (Cr, Mo)-depleted phase could be primarily caused by galvanic coupling of (Cr, Mo)-depleted phase and (Cr, Mo)-rich phase, where (Cr, Mo)-rich phase acted as cathode and the other acted as anode.…”

The corrosion behavior of CoCrFeNiMo x alloys was investigated in aqueous environments, NaCl and H 2 SO 4 solutions, respectively, to simulate typical neutral and acidic conditions. The cyclic polarization curves in NaCl and the potentiodynamic curves in H 2 SO 4 clearly reveal the beneficial effects of Mo and the detrimental effect of r-phase on the corrosion resistance. The X-ray photoelectron spectroscopy results of CoCrFeNiMo x alloys in H 2 SO 4 solution indicate that Cr and Mo predominate the corroded surface of the alloys, where Mo primarily exists in the form of MoO 3 .

“…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.

The present study was focused on understanding the effect of the added nano-Al 2 O 3 on erosioncorrosion behaviour of composite alloying layer. The nano-Al 2 O 3 reinforced composite alloying layer was prepared by duplex surface treatment, which consisted of Ni/nano-Al 2 O 3 predeposited by brush plating and a subsequent surface alloying with Ni-Cr-Mo-Cu by double glow process on the surface of AISI 316L stainless steel. Current response with applied potential, potentiodynamic polarisation curve, electrochemical impedance spectroscopy and weight loss techniques were applied to evaluate the erosion-corrosion behaviour of composite alloying layer compared with the single alloying layer and 316L stainless steel under hydrodynamic conditions. Results of electrochemical measurements showed that the erosion-corrosion resistance of composite alloying layer was lower than that of single alloying layer when the rotating velocity of tested samples was below 2?51 m s 21 , whereas the erosion-corrosion resistance of composite alloying layer was higher than that of single alloying layer when the rotating velocity of tested samples above 2?51 m s 21 . The weight loss rate studies and surface analysis suggested that the dispersive undissolved nano-Al 2 O 3 particles and c9 prime (Ni 3 Al) phase were helpful to improve the erosion-corrosion resistance of composite alloying layer at high rotational speed, though the c9 prime phase was deleterious to corrosion resistance of composite alloying layer.
