“…% of CNT produced the best specific wear rate sample especially in ambient air and having average significant improvement of about 73% for sliding wear resistance. It should be noted that earlier study [21,22] reported the wear improvement about 15%, however the measured the gear wear reported was coupled i.e. sliding and rolling wear resistances.…”

“…The POM powder (KOCETAL® K700) was supplied by El-Slam Company, Cairo, Egypt. Paraffin oil was used to adhere the CNT with the acetal polymer pellets after stirring for approximately 5 min [22]. To produce the study specimens (flanges), the CNT/acetal pellets were firstly are fed into a 400-g capacity hopper.…”

“…In a follow-up work, Yousef et al (2014) refined the CNT dispersion using paraffin oil technique to overcome bubble formation and unmelted pellets problems. The study went on to synthesis a series of CNT/POM that included spur, bevel, helical and worm gears [22]. In the previous studies, the wear resistance of POM gears (rolling and sliding) was improved by adding 0.02 wt.…”

“…While the Acetal pinion, it causes increase in wear, therefore this method can only be applied to visco-elastic material only. The wear resistance of carbon nanotube reinforced Acetal gear was studied by S. Youseff [21] by determining the weight loss of the gear. It was then compared to results from previous research [22].…”

Abstract.Polymer are now widely used as substitute material for steel gear in low load devices. Its failure differs from gears made of steel, thus it is important to categorize the failures shown by polymer gears. Several previous studies noted that wear detection, microstructure surface condition monitoring, weight loss and temperature detection can be used in detecting failure of polymer gear. This article reviews the failure detection method mentioned above. Other researcher works were studied and their findings were extracted in order to identify the methods they used. The most common method used was wear detection and it was supplemented by other methods such as microstructure surface condition monitoring. Failures shown by polymer can be concluded to be tooth breakage, tooth deformation, material removal and surface fatigue.

“…Regarding the wear behaviors of CNT/POM reinforced by PO, Yousef et al . (2013 and 2014) measured the wear rate (sliding and rolling) of four types of CNT/POM gears (spur, helical, bevel and worm) using TS universal test rig . The results showed that the CNT had a significant positive effect on the wear rate reattached until 32%.…”

The paraffin oil dispersion technique innovated in the recent years to synthesize bulk polymer nanocomposite materials has a uniform dispersion. This research work aims to study the effect of added carbon nanotubes (CNTs) on flexural, impact and rheology behaviors of polyoxymethylene (POM) reinforced by 0–0.03 wt% of CNT using paraffin oil dispersion technique. The wettability and lamellar thickness were measured and rheological performance investigated using a parallel plate rheometer. The flexural and impact mechanical properties were also evaluated. The fracture surfaces were then examined by microscopy. The results showed that the energy to break, flexural strength and modulus increased proportionally with the addition of the amount of CNT in the matrix. For the rheology behavior, the viscosity decreased at the low percentage of CNT and then increased with increase in the percentage weight ratio of CNT in the POM matrix. It was also noted that the water contact angle rose with the increase the CNT percentages. Copyright © 2016 John Wiley & Sons, Ltd.
