The slurry erosion behaviour of high velocity oxy-fuel (HVOF) sprayed aluminium bronze coatings

Effect of heat treatment on microstructure evolution and erosion–corrosion behavior of a nickel–aluminum bronze alloy in chloride solution

“…According to the erosion-corrosion testing results in Table 5, a negative synergy is found for all specimens, which implies that the presence of a layer of protective film reduces the erosivity of sands [10][11][12][13][14]17]. The erosion-corrosion behaviour of NAB is affected by the repassivation characteristic of the material.…”

“…This protective film is generally vulnerable to high velocity fluid flow along with solid particle impingement, which usually emerges in propulsion systems. Therefore, surface technologies, such as thermally spray coatings, have been developed for improved erosion-corrosion performance of the NAB in various environments [11][12][13][14]. However, the coating performance is often unsatisfactory due to the presence of micro-defects and micro-cracks in the coating, reducing its integrity and thus the protective ability to the NAB substrate.…”

Erosion and erosion–corrosion performance of cast and thermally sprayed nickel–aluminium bronze

“…Kinetic energy exponents in Table 6 have been obtained for cast NAB, AB coating, NAB coating and 4360 steel. Ductile materials have energy exponent values close to unity while brittle materials have values in a range between 2 and 3 [23][24][25]. Ductile erosion mechanisms are kinetic energy related, whereas brittle materials are influenced by the presence of flaws which accelerate damage rates.…”

The development of nickel-tungsten carbide functionally graded materials by a laser-based direct metal deposition process for industrial slurry erosion applications

“…Such materials would have significant applications in the oil industry for the drilling and pumping of crude oil from the bottom of the sea or ocean, in mineral industries, and in marine and power production industries. There have been many investigations reported [14][15][16][17][18][19] in the literature regarding the slurry erosion behaviour of monolithic materials. However, there are few studies [20][21][22] reported for the slurry erosion resistance of FGMs.…”
