“…Generally speaking, the factors affecting erosion can be divided into three classes, i.e., the properties of target materials, impingement particles, and test conditions. Much attention has been paid in studying slurry erosion of various materials [9][10][11][12][13][14]. Despite the fact that some relationships between the properties of some materials and erosion resistance have been recognized [13], individual materials demonstrated a great difference in erosion resistance in various environments.…”

“…carburizing, nitriding and boronizing. Numerous surface engineering techniques, including low-temperature plasma surface process, laser surface modifications, thermal spraying, chemical and physical deposition and carburizing, have been widely used for improving erosion resistance (Höppel et al , 1999; Jiang et al , 2013; Saleh and Ahmed, 2013; Stack and Abd El Badia, 2006; Toma et al , 2001).…”

Purpose This paper aims to clarify the relationship between the slurry erosion and one of the case hardening treatments, i.e. boronizing in this study, for AISI-5117 steel alloy. AISI-5117 steel alloy was used because of its variety applications in the field of submarine equipment. Most of the slurry erosion factors such as velocity, impact angle and mechanism of erosion were studied at different impact angles. Design/methodology/approach At first, the samples were prepared and subjected to the boronizing treatment in controlled atmosphere. By using a slurry erosion test-rig, all experiments for studying the slurry erosion factors were carried out. Moreover, the studied specimens were investigated via scanning electron microscope, optical microscope and X-ray diffraction to study the erosion mechanism in the different conditions. Findings It was expected that the boronization of the AISI-5117 steel would increase its slurry erosion resistance due to its positive impact on the surface hardness. However, the results observed show the opposite, where the boronization of AISI-5117 steel decreased its slurry erosion resistance as implied by the increase of the mass loss percentage at all impact angles. Originality/value This research, for the first time, exhibits the effect of boronizing treatment on the slurry erosion in different impact factors accompanied by the erosion mechanism at each impact angle.

“…Diana Lopez et al [3] have reported the formation of cracks in the coating and plastic deformation in both the substrate and the coating, especially when the mean impact velocity exceeded a critical value between 6.9 and 8.6 ms −1 . Hoppel et al [4] have coated different combinations of Co/WC and NiCr/Cr 3 C 2 on different alloy substrates of Ni, Cr and Mo combinations and have reported that the slurry erosive wear resistance of coated specimens are greater in comparison to the un-coated substrate. Wang et al [5] have concluded that the slurry erosion resistances of the Ti N coatings were significantly higher than that of the uncoated mild steel and the AISI 304 stainless steel.…”
