Mussel adhesive proteins are known for their high affinity to a range of different surfaces, and they therefore appear as ideal candidates for producing thin inorganic-organic composite films with high robustness. In this work we explore the possibility of making cohesive films utilizing layer-by-layer deposition of the highly positively charged mussel adhesive protein, Mefp-1, and negatively charged ceria nanoparticles. This particular material combination was chosen due to recent findings that such films provide good corrosion protection. Quartz crystal microbalance with dissipation monitoring (QCM-D) was used for following the film formation process in situ on silica surfaces. A close to linear growth of the film with number of deposited layers was found for up to 18 deposition steps, the highest number of depositions investigated in this work. The Mefp-1 concentration during film deposition affected the film properties, where a higher protein concentration resulted in a stiffer film. It was also found that the added mass could be amplified by using a Mefp-1 solution containing small aggregates. The surface nanomechanical properties of dried multilayer films were investigated using peak force QNM (quantitative nanomechanical mapping) in air. Homogeneous surface coverage was found under all conditions explored, and the Young's modulus of the outer region of the coating increased when a higher Mefp-1 concentration was used during film deposition. The nature of the outermost surface layer was found to significantly affect the surface nanomechanical properties. The abrasion resistance of the coating was measured by using controlled-force contact mode AFM.

“…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.…”

“…When Wang et al [71] and Yin et al [72] added Al 2 O 3 to 75Ni and Al using HVOF and plasma spray respectively; an adhesion strength of 22.9 MPa and 28.8 MPa was observed. In comparison, it is clear that an improvement in adhesion strength (35)(36)(37)(38) MPa) is obtained. The 20% improvement in adhesion strength can be attributed to increase in contact points facilitated by the well-flattened splats.…”

“…The results demonstrated the nano particles significantly increased the hardness of coatings (NiCoCrAlY: 350.5, NiCoCrAlY+Al 2 O 3 : 397.8, NiCoCrAlY+SiC: 484.9 and NiCoCrAlY+CeO 2 : 385.7). A further comparative study using nano-CeO 2 and Sm 2 O 3 to reinforce Ni through laser deposition was carried out by Zhang et al [38]; where an improvement in microhardness and wear-corrosion resistance was observed. Deposition of nano-Cr 2 O 3 in combination with Ni-alloys on steel using duplex surface treatment was reported by Liu and Xu [39].…”

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 ...

“…Shi et al [ 30 ] investigated the influence of nanoscaled rare earth La 2 O 3 addition on the wear resistance of Ni60A/SiC laser cladding coating on the 60Mn steel substrate, and proved the improvement of the grain refinement and wear resistance of nano rare earth oxides. Zhang et al [ 31 ] prepared laser cladding Ni-based alloy coatings on low carbon steel substrate with 1.5 wt.% nano-CeO 2 and nano-Sm 2 O 3 addition. Due to the thermodynamic characteristic of nanoscaled rare earth oxides, the morphology of dendrite in the coating has transformed from bulky into fine and compact, and the microhardness, wear resistance and corrosion resistance are greatly improved.…”

Titanium and its alloys are widely used in high-end manufacturing fields. However, their low high-temperature oxidation resistance has limited their further application. Recently, laser alloying processing has attracted researchers to improve the surface properties of Ti, for which Ni coated graphite system is an excellent prospect due to its outstanding properties and metallurgical bonding between coating and substrate. In this paper, nanoscaled rare earth oxide Nd2O3 addition was added to Ni coated graphite laser alloying materials to research its influence on the microstructure and high-temperature oxidation resistance of the coating. The results proved that nano-Nd2O3 has an outstanding effect on refining coating microstructures, thus the high-temperature oxidation resistance was improved. Furthermore, with the addition of 1. 5 wt.% nano-Nd2O3, more NiO formed in the oxide film, which effectively strengthened the protective effect of the film. After 100 h of 800 °C oxidation, the oxidation weight gain per unit area of the normal coating was 14.571 mg/cm2, while that of the coating with nano-Nd2O3 addition was 6.244 mg/cm2, further proving that the addition of nano-Nd2O3 substantially improved the high-temperature oxidation properties of the coating.
