Tribological properties of carbon nanotube/SiO2 combinations as water-based lubricant additives for magnesium alloy

A Comprehensive Review of Water-Based Nanolubricants

“…During the cold rolling of Mg alloy under a single-pass reduction of 10%, the rolling force and rolled surface roughness obtained with dry rolling were decreased by up to 12% and 42.4%, respectively, when using the nanolubricant with the optimal SiO 2 /graphene combinations. It has also been documented that SiO 2 /nanotube hybrid water-based nanolubricant with a mass ratio of 0.3:0.2 can be used for Mg alloy forming according to its excellent tribological properties and load-carrying capacity as well as formation of stable lubricating film on the surface of Mg alloy [113]. These research findings have provided new insights into the potential of applying carbon-based aqueous nanolubricants in Mg alloy forming.…”

“…Multiple studies have mentioned the significance of protective film formation using NPs such as graphene based [73,75,77,134,145,147], ionic liquids [155][156][157], and phosphorus [162]. Some other NPs such as metal oxides [27][28][29][56][57][58], diamond [137], and composites [19,113,115,123] are also able to form a protective film on friction surfaces. Based on previous studies, it is concluded that the protective film not only reduces the friction and wear between friction pairs but also helps in isolating air, thus leading to reduced oxide scale thickness during hot steel rolling [27][28][29].…”

The Influence of Battery Acid on the Destruction of Acrylic Coatings of Car Bodies

“…It should be stressed that information resources in the area of the physico-chemical properties of protective-decorative polymer coatings, constituting the basis for their operational life increase, are continually updated by numerous researchers dealing with this subject [25][26][27][28][29][30][31][32][33][34][35][36][37]. This growing interest in the subject is the result of the growing requirements in regard to the reduction of the contents of volatile organic compounds (VOC), according to directive 2006/42/WE of the European Parliament and The Council.…”

“…This growing interest in the subject is the result of the growing requirements in regard to the reduction of the contents of volatile organic compounds (VOC), according to directive 2006/42/WE of the European Parliament and The Council. Moreover, the permanent introduction of new generation materials (nanofillers, nanopigments [27][28][29][30][31][32][33][34][35][36]) into the market forces examinations (especially accelerated) of coatings produced with the participation of nano-additives in order to evaluate their protective and decorative properties [32,34]. Nowadays, "smart polymer coatings" are also produced, which self-heal defects occurring in their structure under the influence of operational factors.…”

“…The introduction of special substances into the nanocontainers enables one to control final properties of the coatings. In this way, it is possible to obtain smart coatings that are antibacterial, antifouling, self-cleaning, anti-icing, colour-altering, or hydrophobic [22,26,30,35].…”
