All the specimens, which were encapsulated in an identical thermosetting resin, were evaluated at a sliding speed (V=0.6 m/s) and two different normal loads (F=25, 50 N), followed by representing the results in terms of coefficient of friction graphs, retentivity graphs, and wear rate charts. According to the results, the lubricant which comprised a mixture of graphite and MoS2 was superior to the others, with the reduction of COF by 94%. Following that, the MoS2-based lubricant and graphite-based lubricant diminished COF by 91% and 88%, respectively.&nbsp;</div> Solid lubricant, Wheel flange, Rail gauge corner, Pin-on-disc, Wear 61 68 http://ijrare.iust.ac.ir/browse.php?a_code=A-10-282-1&slc_lang=en&sid=1 Kamran Moradian info.ipico@gmail.com 180031947532846002664 180031947532846002664 Yes Isfahan University of Technology, Isfahan, 84156-83111, Iran Mahmoud Farzin farzin@iut.ac.ir 180031947532846002665 180031947532846002665 No Isfahan University of Technology, Isfahan, 84156-83111, Iran Mehdi Karevan mkarevan@cc.iut.ac.ir 180031947532846002666 180031947532846002666 No Isfahan University of Technology, Isfahan, 84156-83111, Iran Saleh Akbarzadeh s.akbarzadeh@cc.iut.ac.ir 180031947532846002667 180031947532846002667 No Isfahan University of Technology, Isfahan, 84156-83111, Iran
