High temperature lubrication and mechanism of sodium carbonate by interface tailoring

Shear-driven reactions of organosulfur compounds on ferrous surfaces: A molecular dynamics study

“…[12] Experimentally, the effect of shear to accelerate chemical reactions can be quantified by measuring the increase in reaction rate or yield with increasing stress. Examples of this experimental approach are studies of bond cleavage [13,14,15], polymerization, [16,17,18] and film formation [19,20]. Specifically relevant to lubricant additives, recent studies have shown that tribofilm growth rates increase with shear stress for zinc dialkyl dithiophosphate (ZDDP) on steel [21], iron [22], silicon [23], and other non-ferrous surfaces [24], as well as for dimethyl disulfide [25,26], diethyl disulfide, and dimethyl trisulfide on copper [27].…”

Design of a high-temperature grease by BP neural network and its preparation and high-temperature performance studies

“…Many excellent hightemperature greases were constantly being discovered. For example, Wang et al found that sodium carbonate melts in the temperature range of the hot rolling and can be used as a lubricant (Wang et al, 2020a(Wang et al, , 2020b. Also, they found that the combination of sodium metasilicate and expanded graphite has excellent lubricating properties (Wang et al, 2020a(Wang et al, , 2020b.…”

Similarly, a study told that graphite as a lubricating substrate combined with amorphous silica and aluminum dihydrogen phosphate can synthesize a high-temperature environmentally friendly grease (Huai et al, 2021).…”
