“…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.…”

“…Zhang et al [16] also showed that PU elastomers with higher elongation at break (520%) had higher resistance to erosive wear compared to other polymers with lower elongation at break such as polytetraluoroethylene (150%). Similarly, Ashraizadeh et al [21] showed that a reduction of the elongation at break of PU at 100°C led to a sudden increase in erosion rate of PU at that temperature.…”

“…Although the PU fabrication process is similar to the methods typically used for polymers, its mechanical properties such as high elongation at break and minimal plastic deformation are comparable to that of vulcanized rubber that has a more complicated production process [14]. PU has beter wear resistance than most polymers [15], rubbers [16], stainless steels [15], and even some hard-faced tungsten carbide-cobalt (WC-Co) coatings [17]. Excellent resistance to wear and corrosion together with ease in fabrication process and low cost has made PU an excellent option for use as protective liners in large-scale applications such as oil and gas pipelines [18].…”

“…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].…”

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.

“…Impact shock exerted on PTFE in a closed steel container (Holt et al 2000) or abrasive erosion of PTFE (Zhang et al 1995) was also reported, without mentioning any reaction processes or mechanisms. The objectives of this study are thus focused (i) on finding out the components enhancing the mechanochemical decomposition of the FCS to incorporate fluorine into SnO 2 nanoparticles and (ii) examining the thermal stability of the modified oxide.…”

Modification of tin oxide nanoparticles by fluorocarbon solids via a mechanochemical route

Interfacial reactions at the surface of SnO 2 nanoparticles adjacent to the fluorocarbon solids (FCS) under mechanical stressing were compared in an attempt to their modification by introducing fluorine and carbon. Emphasis was laid on the comparison of the reactivity of 3 different species of FCS, i.e., polyvinylidene fluoride (PVdF), polytetrafluoroethylene (PTFE), and perfluorooctanoic acid (PFOA). PVdF exhibited the highest reactivity, followed by PTFE and PFOA, as confirmed by Raman, FT-IR, XPS, and 19 F MAS NMR spectra. The preferential reactivity could be explained in terms of the electrophilicity of FCS toward the nucleophilic oxygen in SnO 2 , since the decomposition of FCS is catalyzed by the coexisting SnO 2 . PFOA behaved in a different manner, due to its carboxylic groups. At the same time, carbon nanospecies were introduced as a decomposed product of FCS. This results in the formation of SnO 2 :F/C nanocomposite. Fluorine introduced to SnO 2 survived even after heating up to 600°C either in air or in Ar. This indicates the thermal stability of the present partially fluorinated SnO 2 nanoparticles.
