“…PVD processes allow the deposition of mono-layered or multi-layered coatings, as well as different alloy compositions [ 36 , 37 ]. The authors in [ 38 ] also investigated the influence of different metal coatings on the mechanical and physical properties of carbon fibre reinforced polymers (CFRPs) which have been used increasingly in the aerospace and automotive industries. Maurer et al [ 39 ] showed that multilayer thin films of pure Ti or Ti/TiN deposited on epoxy and PEEK based CFRP increased their erosion resistant significantly.…”

Experimental Investigation of the Wear Behaviour of Coated Polymer Gears

A comprehensive experimental investigation of the wear behaviour of coated spur polymer gears made of POM is performed in this study. The three physical vapour deposition (PVD) coatings investigated were aluminium (Al), chromium (Cr), and chromium nitrite (CrN). Al was deposited in three process steps: By plasma activation, metallisation of Al by the magnetron sputtering process, and by plasma polymerisation. Cr deposition was performed in only one step, namely, the metallization of Cr by the magnetron sputtering process. The deposition of CrN was carried out in two steps: the first involved the metallization of Cr by the magnetron sputtering process while the second step, vapour deposition, involved the reactive metallisation of Cr with nitrogen, also by the magnetron sputtering process. The gears were tested on an in-house developed testing rig for different torques (16, 20, 24 and 30 Nm) and rotational speed of 1000 rpm. The duration of the experiments was set to 13 h, when the tooth thickness, and, consequently, the wear of the tooth flank was recorded. The experimental results showed that the influence of metallisation with aluminium, chromium, and chromium nitrite surface coatings on the wear behaviour of the analysed polymer gear is not significant. This is probably due to the fact that the analysed coatings were, in all cases, very thin (less than 500 nm), and therefore did not influence the wear resistance significantly. In that respect, an additional testing using thicker coatings should be applied in the further research work.

“…[71,74,75] It is, therefore, feasible that thin metal and metal oxide coatings could be used to provide polymer composite materials with the ability to resist viruses, although this has not yet been evaluated. Thin metal coatings can be applied to polymer composites using techniques such as cold spray, [76][77][78] pulsed gas dynamic spray, [79] magnetron sputtering, [80] detonation gun spraying [81] and 3D printing. [82] A continuous metallic film should be sufficient to impart anti-viral properties to polymer composite materials.…”

Towards antiviral polymer composites to combat COVID‐19 transmission

et al. 2021

View full text Add to dashboard Cite

Polymer matrix composite materials have the capacity to aid the indirect transmission of viral diseases. Published research shows that respiratory viruses, including severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2 or COVID‐19), can attach to polymer substrata as a result of being contacted by airborne droplets resulting from infected people sneezing or coughing in close proximity. Polymer matrix composites are used to produce a wide range of products that are “high‐touch” surfaces, such as sporting goods, laptop computers and household fittings, and these surfaces can be readily contaminated by pathogens. This article reviews published research on the retention of SARS‐CoV‐2 and other virus types on plastics. The factors controlling the viral retention time on plastic surfaces are examined and the implications for viral retention on polymer composite materials are discussed. Potential strategies that can be used to impart antiviral properties to polymer composite surfaces are evaluated. These strategies include modification of the surface composition with biocidal agents (e.g., antiviral polymers and nanoparticles) and surface nanotexturing. The potential application of these surface modification strategies in the creation of antiviral polymer composite surfaces is discussed, which opens up an exciting new field of research for composite materials.

“…Resulting, only individual particles embedded in the epoxy matrix. However, Fallah et al [285] also noticed that delamination of the carbon fibre-reinforced polymers (CFRPs) by cold spray deposition occurred at higher gas pressures. The Copper coatings protect the CFRP from any possible damage but also improves the overall properties of the composites.…”
