“…There exists a synergism of acidic fluid flow and sand impact on electrochemical corrosion behaviour of investigated materials. The impingement of a high speed acidic liquid-particle will cause severe plastic deformation on the investigated materials and result in inhomogeneous stress distribution and electrochemical properties [29]. The microcell of strain difference is formed between the high strain domains, such as plough ridge and protuberance at the pit edges and low strain domain.…”

In order to overcome the problem of corrosion wear of AISI 316L stainless steel (SS), 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 subsequent surface alloying with Ni-Cr-Mo-Cu by a double glow process. The microstructure of the two kinds of nanoparticle reinforced Ni-based composite alloying layers was investigated by means of SEM and TEM. The electrochemical corrosion behaviour of composite alloying layers compared with the Ni-based alloying layer and 316L SS under different conditions was characterized by potentiodynamic polarization test and electrochemical impedance spectroscopy. Results showed that under alloying temperature (1000 • C) conditions, amorphous nano-SiO 2 particles still retained the amorphous structure, whereas nano-SiC particles were decomposed and Ni, Cr reacted with SiC to form Cr 6.5 Ni 2.5 Si and Cr 23 C 6. In static acidic solution, the corrosion resistance of the composite alloying layer with the brush plating Ni/nano-SiO 2 particles interlayer is lower than that of the Ni-based alloying layer. However, the corrosion resistance of the composite alloying layer with the brush plating Ni/nano-SiO 2 particles interlayer is prominently superior to that of the Ni-based alloying layer under acidic flow medium condition and acidic slurry flow condition. The corrosion resistance of the composite alloying layer with the brush plating Ni/nano-SiC particles interlayer is evidently lower than that of the Ni-based alloying layer, but higher than that of 316L SS under all test conditions. The results show that the highly dispersive nano-SiO 2 particles are helpful in improving the corrosion wear resistance of the Ni-based alloying layer, whereas carbides and silicide phase are deleterious to that of the Ni-based alloying layer due to the fact that the preferential removal of the matrix around the precipitated phase takes place by the chemical attack of an aggressive medium.

“…The dissolution rate of a material is affected by deformation [23,24]. In the model, site-site bonds are deformed under the wearing force and the dissolution rate of a bond changes with strain.…”

“…In general, corrosion increases the surface irregularity, which leads to enhanced stress concentration and thus the probability of mechanical failure. On the other hand, the increased stress concentration may result in larger plastic deformation that in turn increases the corrosion rate [2]. As a result, wear of materials can be significantly increased when corrosion is involved [3].…”

“…The strain-difference cell induced by the higher dislocation density of pits' and grooves' bulging edge comparing to the pit's bottom, in which pits and grooves are generated by abraser 's rubbing and impacting the surface of material [9] , and the accelerated brittle flaking by environmental brittleness under impact-erosion condition [10] etc. That interphase corrosion in multiphase alloy causes carbide's flaking [11] , and that corrosion medium is squeezed into crack and promotes the development of crack, which accelerates corrosion flaking [12] to cause the acceleration of corrosion to abrasion. Apparently, the behavior and mechanism of corrosive wear under impact stress are correlated to the value of the impact force.…”

The impact corrosion-abrasion properties and mechanism of high manganese steel were investigated under different impact energies. The result shows that the wearability of the steel decreases with the increase of the impact energy. The dominant failure mechanism at a lower impact energy is the rupture of extrusion edge along root and a slight shallow-layer spalling. It transforms to shallow-layer fatigue flaking along with serious corrosion-abrasion when the impact energy is increased, and finally changes to bulk flaking of hardened layer caused by deep work-hardening and heavy corrosion-abrasion.
