Raman scattering is utililized to investigate structural - disorder in
solid lubricant films. MoS2 films used in tribological studies for ae
rospace applications may be prepared by pulsed laser deposition (PLD)
or by ion sputter deposition. Raman scattering spectra were obtained o
n a set of standard MoS, compounds and a set of PLD films. These depos
ition processes incorporate changes into the crystallinity of the depo
sited films and the Raman data from these films were studied with a cu
rve fitting program to analyze-the defects generated by the PLD proces
s. The curve fitting program shows that MoS2 PLD films can be categori
zed by peak position, half-band width, integrated area and linear inte
nsity measurements. The Raman data appear to be more sensitive to crys
tal order in the x-y symmetry plane than to order in the z axis of the
crystal.
