“…The static corrosion of Fe-B alloy in liquid zinc indicated that a well-adhered interfacial film could gain by controlling the orientation and lamellar spacing of Fe2B to produce a pinning effect at the orientation interface [21,22]. Moreover, the liquid zinc temperature and Fe2B morphologies (netlike and columnar Fe2B) manifested that the corrosion dominates the product dissolution, while flow erosion governs the Fe2B spalling in flowing liquid zinc, which may depend on the interfacial pinning effect [23,24]. However, the effect of Fe2B lamellar spacing and product deposition on the film structure and morphology under flowing conditions should emphasize owing to the hydrodynamics of flowing zinc and the effect of flow on corrosion.…”

Cavitation can be described as a hydrodynamic phenomenon which involves in the formation and collapse of vapor bubbles in a liquid medium. It always accelerates the cavitation damage and brings about multi-scale interactions of cavitation erosion between materials and fluids. For example, corrosion by dissolution/reaction can accelerate cavitation erosion under different liquid temperatures and velocities to alter interface films, and multiphase interface structure can also in turn affect the interfacial flow regime to induce cavitation in various fluids. In this chapter, interfacial characteristics and erosioncorrosion mechanism of directionally solidified (DS) Fe-B alloy with various Fe2B lamellar spacing in flowing zinc were investigated. The results indicate that the formation of adhesive interfacial film not only depends on erosion time and Fe2B lamellar spacing, but also relies on epitaxial ζ accumulation determined by zinc flow effect. Meanwhile, microturbulence of flowing zinc can result in the formation of slip bands and erosion pits on the ζ-FeZn13 surface. The flow-induced localized corrosion appears to accelerate the erosion-corrosion damage of interfacial adhesive film structure and morphology, which reveals underlying erosion mechanism of liquid metal.

“…Bauer et al revealed the influence of various grain boundaries on liquid metal-induced embrittling behavior in bcc iron [13], Shahryari et al showed the effect of orientation on pit corrosion susceptibility [14], and Lu et al investigated the influence of orientation on stress corrosion cracking [15]. The orientation effect mentioned above stems from the close-packed planes of the crystal, whose high atomic coordination and binding energy lead to good material properties [16]. In addition, Song et al studied zinc coating/steel substrate interface cracking behavior, and the results revealed that the orientation and size of the zinc coating have an obvious impact on the adhesion.…”

“…Based on the aforementioned investigations, it can be inferred that the crystal orientation and grain size of an Fe-B alloy may affect the interface structures and the corrosion resistance of the alloy in hot-dip galvanization bath. Although some previous works revealed that the grain orientation can affect corrosion resistance to liquid metal [16,21,22], the microstructural regulation and synergy of the as-received interfaces of alloys need to be studied and clarified. Therefore, in the present work, the interfacial characteristics and corrosion behavior of a directionally solidified Fe-B alloy in liquid zinc, as well as the alloy's interfacial adhesion capability, were extensively investigated.…”

“…In addition, Song et al studied zinc coating/steel substrate interface cracking behavior, and the results revealed that the orientation and size of the zinc coating have an obvious impact on the adhesion. For instance, the stress levels in grains with the [0001] direction parallel to the interface are much lower than in grains with the [0001] direction perpendicular to the interface [16]. Furthermore, the adhesion of the coating/substrate interface can be affected by the segregation of alloying elements, surface roundness and interfaces [17e20].…”

a b s t r a c t The effects of orientation and lamellar spacing on the interface microstructure and corrosion behavior of a directionally solidified (DS) Fe-B alloy in a hot-dip galvanization bath were investigated. The results indicated that the microstructure of the DS Fe-B alloy consisted of oriented a-Fe and Fe 2 B grains. The oriented Fe 2 B with [002] preferred growth orientation displayed low-angle grain boundaries on the Fe 2 B (001) basal plane. The DS Fe-B alloy with Fe 2 B vertical to the corrosion interface possessed the best corrosion resistance to liquid zinc owing to the formation of an interface-pinning multilayer induced by the Fe 2 B orientation. The epitaxially grown columnar z-FeZn 13 products were controlled by the geometric constraint of Fe 2 B grain orientation and size, and a mechanism model that explains the interfacial orientation-pinning behavior is discussed in detail. Transmission electron microscopy (TEM) results revealed that the possible orientation relationships of the oriented Fe 2 B and columnar z-FeZn 13 products are (001) Fe2B //(À402) z-FeZn13 and [002] Fe2B //[110] z-FeZn13 . The corrosion damage of the DS Fe-B alloy with Fe 2 B [002] orientation vertical to the corrosion interface in liquid zinc was governed by the competitive mechanisms of Fe 2 B/FeB transformation and microcrack-spallation resistance, which is proposed as being the result of a multiphase synergistic effect in the micro-structures.

The In-situ composite of metal matrix AA6063-xTiC (x = 0 wt. %, 3wt. %, 6 wt. %, 9 wt. %) were mixed with particulates of Tic, were synthesized by the reaction of K 2 TiF 6 and graphite with aluminum melt at 1000°C. These composites were heat treated differently to form various sets like solution zed and solution zed-aged, where they were compared with as-cast composites for erosive wear performance by testing pot type slurry-erosive wear device, respectively. This study showed an increase in wear resistance for slurry erosion upon solution zed-aged heat treatment and with a rise of Tic particulates.
