| Abstract: | Some molybdenum complexes of N-isonicotinyl-N’
aryl thiosemicarbazides were studied for their tribological activity using four
ball test machine. All the compounds were found to be significantly effective
extreme pressure lubrication additives. Their EPL efficiency has been compared
on the basis of various tribological parameters like wear scar diameter,
friction coefficient, initial seizure load (ISL), 2.5s seizure delay load (2.5
s SDL), weld load (WL), mean Hertz load (MHL), pressure wear index (PWI) and
flash temperature parameter (FTP). The topography of the wear scar surface of
balls in presence of p-chlorophenyl
derivative has been studied by scanning electron microscopy at 2.5s seizure delay
load and just before weld load. Auger electron spectroscopy has been used to
analyze the wear scar surface at just before weld load. |
