The influence of pre-IGC damage and IGC damage during sliding on the tribology behavior of tempered 13Cr martensitic stainless steel was studied systematically in dry, DM water and nitric acid sliding conditions using a ball on plate configuration with an aim to elucidate the mutual dependence on tribology performance. The coefficient of friction decreased in the order COF _{Dry sliding (Case A)} > COF _{IGC+ Dry sliding (Case C)} > COF _{Under DM water sliding (Case B)} > COF _{Under nitric acid sliding (Case D)} > COF _{IGC+ Under nitric acid sliding (Case E)}. The COF values for IGC attacked conditions (0.49 in Case C, 0.3 in Case D) are lower than that of unattacked conditions (0.72 in Case A, 0.4 in case B) irrespective of lubrication. The specific wear rate (k) decreased in the order k _{Case C} > k _{Case A} > k _{Case B} > k _{Case D} > k _{Case E}. The k value for the Case E (3.3 × 10^–6 mm³/Nm) is almost 120 times lower than that of Case C (408 × 10^–6 mm³/Nm). Such variations were explained based on the combined lubrication effects of nitric acid and thicker oxides formation in the wear track region as confirmed by scanning electron microscopy/energy dispersive spectroscopy and Raman spectroscopy analysis. 3D profilometry and scanning electron microscopy examination of wear tracks revealed mechanical polishing type wear mechanism in nitric acid sliding conditions whereas severe abrasive and severe adhesion plus oxidational wear mechanism in dry sliding conditions of unattacked and IGC attacked conditions, respectively. The mechanical polishing is the synergistic effect of wear and corrosion, ascribed to the colloidal action of the eluted nano-sized carbides from tempered MSS matrix into the sliding nitric acid solution. Despite lower k and COF in nitric acid sliding conditions, accelerated IGC damage occurred in the subsurface of wear track and possibly due to the accelerated dissolution at the acid trapped locations. This study also suggests the importance of considering the subsurface characterization while studying the tribocorrosion behavior of stainless steels in IGC prone conditions.
