Tribological Properties of Magnesium Ion-exchanged α-Zirconium Phosphate as a Solid Lubricant Additive in Lithium Grease

Ionothermal Synthesis of Novel Layered Magnesium Phosphate and its Tribological Properties as Grease additives

“…Based on crystal structures, previous research in this area has mainly focused on layered materials, such as layered silicates, layered double hydroxides and layered phosphates. [5][6][7][8][9][10][11][12][13][14][15][16] Despite progress substances retain defects, and further research is needed. For example, partially layered silicates fail to improve the loadcarrying capacity of lubrication oil and grease, layered zirconium phosphates have a high raw material cost, and health hazards are an issue for some materials.…”

“…Due to the scarcity of molybdenum resources and failure due to facile oxidation, alternatives for MoS 2 are needed. Based on crystal structures, previous research in this area has mainly focused on layered materials, such as layered silicates, layered double hydroxides and layered phosphates [5–16] . Despite progress substances retain defects, and further research is needed.…”

Tribological Performance of Nylon Composites with Nanoadditives for Self-Lubrication Purposes

“…Since a significant part of the energy required for industrial component performance is lost in form of heat due to friction [ 2 ], new strategies are required to develop low-friction components. Traditionally, these strategies have been focused on modifying surfaces through different treatments to improve surface hardness [ 3 , 4 ], or to develop hard coatings deposited by physical [ 5 ] or chemical vapor deposition (PVD and CVD) [ 6 ], and the development of new lubricants [ 7 ]. However, some friction and wear phenomena are characterised by different scale processes (ones at atomic or molecular scales and others at a scale of roughness of approximately 1–20 μm [ 8 ]) that operate simultaneously.…”

“…As stated previously, bearings, and particularly bearing cages, are one of the mechanical applications where low-friction polymers can play an essential role in order to achieve a high performance under high speed and temperature conditions by means of reducing the wear between the cage and rolling elements, as investigated by Fersa Bearings S.A. [ 5 , 6 , 7 , 8 , 9 ] and other authors [ 10 , 11 ].…”
