The synergism between wear and corrosion can accelerate material degradation and further shorten the service life of engineering applications.

High-strength glass fabric (HSGF)/phenolic laminates modified with different contents of carbon nanotubes (CNTs) were fabricated by hot-compression technique. The effects of CNTs on the interface of HSGF/phenolic, interlaminar shear strength (ILSS) and water-lubricated tribological performance of HSGF/phenolic laminate were investigated. The ILSS of the laminates were tested on a universal testing machine (DY35), and the tribological properties were evaluated by a block-on-ring tribo-tester. The interfaces of HSGF/phenolic and the worn surfaces of the laminates were analyzed by scanning electron microscope. The results showed that the moderate incorporation of CNTs improved the interface of HSGF/phenolic and accordingly enhanced the ILSS of the laminate. Besides, the friction coefficient of HSGF/phenolic laminate sliding against stainless steel in water can be remarkably stabilized and lowered by the incorporation of CNTs due to the better water lubrication induced by added CNTs and the intrinsic self-lubrication of CNTs which were further graphitized during the friction and wear process. And the wear rate of the laminate can be accordingly reduced by 1 order of magnitude. The results indicate that CNTs have excellent potential in enhancing both ILSS and tribological fabric/polymer laminate composite, which will greatly improve the current situation of deterioration on mechanical properties by adding traditional solid lubricants.

In this work, a series of experiments were conducted to evaluate the effect of applied potential on the tribocorrosion behavior of 410SS using a tribometer integrated with an electrochemical workstation. Results show that tribocorrosion rate of 410SS varies with applied potential and reaches a maximum at À0.1 V. By applying potential pulse method, it indicates that the repassivation kinetics of 410SS is much slower than general stainless steels.The XPS results reveal great changes in the composition of tribocorrosion products, which are enriched in Fe 3 O 4 and Fe(OH) 2 in the lower potential range while become Fe 2 O 3 , FeOOH, and Fe(OH) 3 at more positive potential. The characteristics of tribocorrosion products depend on surface chemistry which varies in compliance with applied potential, and thus, alters the tribocorrosion rate of 410SS. Moreover, the synergistic effect between wear and corrosion was quantified, showing that pure mechanical wear and corrosion-induced wear were the main reasons for the degradation of 410SS.

2015): Combined effect of nano-SiO 2 and nano-Al 2 O 3 on improving the tribological properties of Kevlar fabric/phenolic laminate in water, Tribology Transactions, Abstract The combined effect of nano-SiO 2 and nano-Al 2 O 3 as fillers on the tribological properties of Kevlar fabric/phenolic laminate (KFPL) in water was investigated. Results showed that the single addition of nano-SiO 2 at proper content decreased the friction coefficient of KFPL to an ultra-low value at the cost of the increased wear rate. And the single addition of nano-Al 2 O 3 at proper content reduced the wear rate of KFPL with fluctuating the friction coefficient curve.Excitingly, the combined addition of nano-SiO 2 and nano-Al 2 O 3 endowed KFPL with not only ultra-low friction coefficient originated from nano-SiO 2 , but also improved wear resistance benefited from nano-Al 2 O 3 . This means that the combined addition of nano-SiO 2 and nano-Al 2 O 3 can bring the positive effects of the two fillers into full play, and inhibit their negative aspects to some extent.
