Abstract
In present experimentation study, iron (Fe) matrix-based self-lubricating composite samples were prepared using powder metallurgy process. Tribological as well as mechanical properties of iron molybdenum-based composites with varied content of barium fluoride as solid lubricant were studied under different experimental conditions. The influence of applied normal load (NL) and sliding distance (SD) on friction and wear behaviour was studied. Dry sliding tribological tests were performed on reciprocating ball-on-disc tribometer. From the results, it was reported that hardness and compressive strength were higher for base composition compared to the composites samples. Introduction of barium fluoride increases the tribological properties of the composite. Coefficient of friction (COF) and wear volume (WV) were least for 8 wt% solid lubricant sample. Self-lubricating behaviour of the BaF2 reinforcement in the matrix material was attributed to enhancement in friction and wear properties of the composite.
