  The thermal effects of plastic and frictional heat generation and elevated
temperature were examined along with the role of adhesion in the context of
galling wear, using a representative crystal plasticity, normally loaded,
sliding surface model. Galling frequency behaviour was predicted for 316L
steel. Deformation of the surfaces was dominated by the surface geometry, with
no significant effect due to variations in frictional models. Plastic and
frictional heating were found to have a minimal effect on the deformation of
the surface, with the rapid conduction of heat preventing any highly localised
heating. There was no corresponding effect on the predicted galling frequency
response.
  Isothermal, elevated temperature conditions caused a decrease in galling
resistance, driven by the temperature sensitivity of the critical resolved
shear stress. The extent of deformation, as quantified by the area of
plastically deformed material and plastic reach, increased with temperature.
Comparisons were made with literature results for several surface amplitude and
wavelength conditions. Model results compared favourably with those in the
literature. However, the reduction in predicted galling resistance with
elevated temperature for a fixed surface was not as severe as observations in
the literature, suggesting other mechanisms (e.g. phase transformations,
surface coatings and oxides) are likely important.
