... lubrication, whereas at high temperatures lubricious oxides (NiO, NiMoO 4 , and MoO 3 ), silver molybdates (Ag 2 MoO 4 , Ag 2 Mo 2 O 7 ), and hBN contributed to lowering the coefficient of friction as well as wear-rate. Email: smitagupta.rs.mec19@itbhu.ac.in 1 Corresponding author. Email...

...Qingqing Yan; Qiuying Chang; He Yang; Lichun Hao; Rongqin Gao In the operation of the machine, the tribological properties of the lubricant are apt to deteriorate with temperature elevation. Therefore, it is of great significance to seek a lubricant additive with good high-temperature tribological...
