“…The existence of a maximum value for the shear stress at a certain depth from the surface has been also shown quantitatively in previous studies by inite element modelling [14]. Detachment of fragments and, therefore, wear of the target material occur as a result of the intersection and extension of cracks formed below the worn surface [14,16,43,48]. The surface of PU samples worn by this mechanism does not have regular paterns.…”

“…The mechanical properties of PU are sensitive to temperature and may vary signiicantly even by changing the temperature by around 40°C [21]. Thus, the temperature rise during the wear experiment may afect the erosion resistance of PU [14,16,38,41,[43][44][45][46].…”

“…Unlike metals, the mechanical properties of PU may vary signiicantly even by temperature variation within the range of ±40°C. The fact that the temperature rise of as much as 50°C can occur during the wear process of PU elastomers emphasizes the importance of knowledge about the efect of temperature on the wear resistance of PU [38,43]. In this section, the efect of temperature on wear resistance of PU and rubber elastomers will be discussed and previous studies related to this topic will be reviewed.…”

“…It was found that the temperature rise afected the wear rate by varying the hardness of the PU. Zhang et al [43] employed a grit blasting chamber to evaluate the efect of thickness of a PU liner on its erosion performance. It was found that the heat generated by hysteresis and friction forces increased the temperature of the PU in the layer beneath the surface.…”

“…On the other hand, fewer studies have focused on FE modelling of the solid particle erosion of soft elastomeric materials such as PU. In a recent study, Zhang et al [43] simulated the impact of a single particle on PU liners by a FE modelling approach. In this model, an isotropic hardening elastic-plastic constitutive law was selected for the material formulation, and material removal was modelled by deleting the elements that exceeded the failure strain of the PU.…”

Material removal caused by the impact and sliding of a stream of particles is a typical wear mode in the oil and gas industry. Protective coatings can be employed to increase the service life of equipment that is exposed to harsh erosive and abrasive environments. Among all the types of protective coatings and liners, polyurethane elastomers have received great atention owing to their excellent wear resistance and comparatively low cost that would allow for large-scale applications. The excellent wear resistance of polyurethane elastomers is a result of their high resilience and propensity to elastic deformation that enables the absorption of impact energy of erodant particles with minimal damage. The relation between the wear resistance of polyurethane and its mechanical properties has been the subject of previous studies. This chapter reviews the research that has been conducted to study the wear resistance of polyurethane elastomers. Testing apparatuses employed, material characterization techniques, evaluations of material removal mechanisms, and parameters with the strongest efect on wear resistance of polyurethane elastomers are herein explored. A review of inite element modelling approaches for in-depth study of the wear phenomenon of polyurethane elastomers is also presented in this chapter.

Up to now, it is a major challenge to protect leading edge of the blades from solid particle erosion. Herein, we propose a structure optimization strategy to fabricate non‐woven (NW) enhanced thermoplastic polyurethane nanocomposite films (thermoplastic polyurethane [TPU]‐NW@G/Cx) with “sandwich‐like” structure by hot pressing technology. TPU NW/graphene nanoplates/carbon nanotube (NW@G/Cx) interlayer film were first fabricated by spraying method. Then the interlayer film was laminated between TPU films to fabricate nanocomposite films. Such prepared TPU‐NW@G/Cx film shows excellent solid particle erosion resistance and high‐tensile strength. For example, the “steel‐and‐mortar” structure of NW fabric in TPU film results in high‐tensile strength of 45 MPa and storage modulus of 21.2 MPa for TPU‐NW@G/C1.0, increasing by 25% and 171% compared with original TPU film (35 MPa, 8 MPa), respectively. In addition, compared with pure TPU film, the “sandwich‐like” structure endows TPU‐NW@G/C1.2 with excellent solid particle erosion resistance and the thermal conductivity (0.251 W/m·K). These superior properties extends application of the TPU‐NW@G/Cx film on wind turbine blades.

A coating composed by methyl phenyl silicone resin (PSi) and furan resin (FR) was prepared, and its curing mechanism, heat resistance, and anticorrosion properties were investigated by Fourier transform infrared spectroscopy, thermogravimetric analysis, electrochemical test, and chemical resistance test. Aldol condensation reaction between FR and PSi occurred at below 200°C, and PSi underwent self‐multidehydrogenation at above 200°C. These curing reactions gave excellent thermal stability and anticorrosion properties. Compared with pure PSi, the blended containing lower than 20 wt% FR had better thermal properties, manifested as over 390°C of 5 wt% weight loss temperature and over 40% of char yield at 800°C. The adhesion property of cured blended system on the metal surface reached the first level which exceeded that of pure PSi coating (the third level). Furthermore, the corrosion resistances of coating in acid, alkali, and salt environments were all improved compared with those of monomeric polymer coating. The impedance of blended coating in 3.5% NaCl solution decreased with increasing FR content, which was 1.8 × 106 Ω cm2 when the FR content was 40%, being higher than that of pure PSi coating (7.12 × 105 Ω cm2). This was mainly due to the formation of a cross‐linked network structure based on Si―O―C bond and the enhanced adhesion of cured blended coating. In addition, the surface roughness of cured blended coating was below 2.0 μm, which may have a positive effect on drag reduction in real applications.
