The tribological properties of the latter greases are compared using an Optimol SRV reciprocating friction and wear tester. The morphologies of the worn surfaces are traced by a scanning electron microscope (SEM) and the chemical states of several typical elements on the worn surfaces are examined by x-ray photoelectron spectroscopy (XPS). The results indicate that the new grease has a low friction coefficient and good wear-resisting ability. This is attributed mainly to tribochemical reactions between the grease components and the friction surface with formation of a film that includes CaSO 3 , CaCO 3 , and CaO as well as compounds of lithium, boron, etc. Springer Science+Business Media New York, 2015 lithium-calcium grease nationallicence boundary lubrication nationallicence tribological properties nationallicence SEM nationallicence XPS nationallicence Xia Yanqiu North China Electric Power University, Beijing, China aut Wen Zhenzhong North China Electric Power University, Beijing, China aut Feng Xin North China Electric Power University, Beijing, China aut Chemistry and Technology of Fuels and Oils Springer US; http://www.springer-ny.com 51/1(2015-03-01), 10-16 0009-3092 51:1<10 2015 51 10553 https://doi.org/10.1007/s10553-015-0569-x text/html Onlinezugriff via DOI BK010053 XK010053 XK010000 Metadata rights reserved Springer special CC-BY-NC licence nationallicence 1 research-article jats NATIONALLICENCE NATIONALLICENCE NL-springer NATIONALLICENCE 856 40 https://doi.org/10.1007/s10553-015-0569-x text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Xia Yanqiu North China Electric Power University, Beijing, China aut NATIONALLICENCE 700 1- Wen Zhenzhong North China Electric Power University, Beijing, China aut NATIONALLICENCE 700 1- Feng Xin North China Electric Power University, Beijing, China aut NATIONALLICENCE 773 0- Chemistry and Technology of Fuels and Oils Springer US; http://www.springer-ny.com 51/1(2015-03-01), 10-16 0009-3092 51:1<10 2015 51 10553
