“…7 shows that nanostructured ZrO 2 additions increases the hardness of the nickel-based alloy. The same behavior was reported by other authors after addition of hard particles such as (Al 2 O 3 , CeO 2 , SiC, WC) at a nickel alloy [1,3,16]. However, MA coatings have higher hardness than Dual ones.…”

“…They observed that the wear resistance of the Ni modified coating is increased relatively to the CrC-free Ni-based alloy. Wang et al [16] investigated the effect of three nano-particles additions (Al 2 O 3 , SiC, CeO 2 ) on the high temperature wear behavior of a Ni-based alloy coatings produced by laser cladding technique and reported that the addition of these nanoparticles increased the wear resistance of the coatings. Regarding the effect of incorporation of ZrO 2 particles in a Ni matrix, it has also been extensively studied [17][18][19][20]; however, only electrodeposited coatings have been concerned.…”

“…The oxidation of metals may influence wear and damage mechanisms [11]. The wear behavior of MCrAlY alloys has been studied by several authors, seeking to improve the high-temperature performance with the inclusion of ceramic particles [12][13][14][15][16][17]. This study evaluated the friction and wear behavior at high temperature (500 1C) and room temperature, in static air, of two laser coatings made with NiCoCrAlY and CoNiCrAlY superalloys and opti-mized laser cladding parameters as a novel alternative to thermal spray coating process.…”

Temperature can have a significant effect on the extent of wear damage of metallic components. Thermal barrier coatings can improve the high temperature tribological and friction wear behavior. In this work the dry friction and wear behavior at low and high temperature of NiCoCrAlY and CoNiCrAlY laser cladding coatings were evaluated, as well as for the austenitic stainless steel AISI 304 used as substrate. Dense coatings, with good bonding to the substrate was obtained by coaxial laser cladding tracks (40% overlapping), with previously optimized laser parameters. Tribological wear tests were performed by sliding wear at room temperature and 500 1C, with an Al2O3 ball on disk configuration tribometer. The wear scar surface was evaluated by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) microanalysis. The 3D topography of the wear track was determined by inductive contact profilometer which enabled the wear rate calculation. The microstructure of the coatings consists of γNi/β-NiAl or γCo/β-(Co,Ni)Al phases depending on the chemical composition of the alloy, as confirmed by X-ray diffraction (XRD) analysis. The wear test results show a reduction in wear rate at high temperature for all materials tested. For the NiCoCrAlY coating, the high temperature also reduces the friction coefficient, while it significantly increases the friction coefficient of CoNiCrAlY coating. The main damage mode is abrasion and adhesion, caused by the oxide and partially-oxidized particles in the contact surface. The coatings and substrate results were compared, resulting in an improved wear behavior.

“…There is no significant variation observed in the porosity, surface roughness and adhesion strength with the addition of nano-Al 2 O 3 particles. The adhesion strength from the stud pull off test was found to be in the range of [35][36][37][38] MPa for all the coating compositions tested. Investigating the macroscopic images of the failed samples as shown in figure 6, localised failing of the coating can be observed.…”

Development of nanostructured high velocity oxy-fuel (HVOF) coatings with low porosity, high strength and increased wear resistance is still in its infancy. Combining nanoparticles with conventional microscale powders are increasingly being investigated to use with feedstock materials for thermal spray processes. Accordingly, this work investigates the addition of nano-Al 2 O 3 particles on the microstructure and erosion wear of NiCrSiB HVOF coating in a stainless steel (AISI 304) substrate. Particle analysis of the NiCrSiB feedstock was conducted and the maximum allowable addition of Al 2 O 3 nanoparticles have been identified using the 'mass mixture ratio' model considering both the particle size and density. Consequently, two cases are considered and their performance analysed: a maximum allowable case of 1.4 wt%, followed by a 0.17 wt% addition of nano-Al 2 O 3 with NiCrSiB. Scanning Electron Microscope (SEM), Energy Dispersive Spectroscopy (EDS) and x-ray Diffraction (XRD) analysis were employed to inform the microstructure, material composition and phase spectrum of the resulting coatings. Subsequently, the nanostructured coating was exposed to both a pull-off adhesion strength test and hot air jet (450°C) hard particle erosion to characterise its performance. It was found that the microhardness of the HVOF NiCrSiB coating improved from 576 HV 0.3 to 748 HV 0.3 with the addition of 1.4 wt% nano-Al 2 O 3 . Furthermore, the nanostructured coating also exhibited high erosion resistance at a 90°erodent impact angle. The increase in erosion wear resistance was due to the increase in the hardness as a result of the nano-Al 2 O 3 addition. IntroductionSolid particle erosion wear plays an important role in the material degradation process of engineering components [1-3], including turbines, thermal power plants, pipelines, hydropower machinery and combustion systems [4,5]. According to Martinella [6], one of the major industries affected by solid particle erosion are coal based electric power plants. This is caused as a result of the fly ash interaction with the wall surfaces facilitated by the high-temperature flue gases. The prolonged effect of this causes the boiler components to fail and currently account for ∼25% of the down time [7]. The subsequent cost effect of erosion wear damage in such cases is often as high as 54% of the overall maintenance cost [8,9]. Consequently, coatings that can improve the surface resistance to solid particle erosion wear along with high-temperature oxidation protection systems are increasingly being sought.Among the numerous solution available to prevent or control the fly ash erosion, surface coatings [10] are the most widely adopted technique [11][12][13]. When it comes to coating methodology, several techniques are available including vapour deposition [14], electrochemical, sol-gel [14] and thermal spraying [14]. Among these different coating techniques, thermal spray techniques [15,16] have received increased attention largely due to their capacity to accommodate a range of ...
