A statistical expression, showing as a function of the film parameter (film thickness/surface roughness or h/σ) the fractional reduction in fatigue life at “full film” conditions due to the competition between asperity induced fatigue and fatigue due to indigenous surface defects and subsurface inclusions, is presented.
