By conducting experiments in accordance with the ASTM D 2596 standard as well as the ASTM 2266 standard, respectively, it was possible to determine how graphite powder's use as an intense pressure additive as well as an anti-wear additive affected the tribological characteristics of lithium grease. In order to determine the thresholds for ideal weld load as well as wear scar diameter, signal to noise ratio analysis also performed. According to a signal-to-noise ratio analysis, graphite powder of particle sizes of 0.5 micron and 5% by volume in lithium grease showed the greatest load carrying capacity compared to other combinations, and graphite powder of particle sizes of 5% by volume and 1.5 micron in lithium demonstrated the smallest wear scar diameter compared to other combinations. Weld load and worn scar diameter significant factors were found by analysis of variance. According to the analysis of variance, graphite volume percentage contributed more than graphite particle size to weld load and graphite volume percentage contributed more than graphite particle size to wear scar diameter. When compared to ordinary lithium grease, it was found that graphite with lithium grease at ideal concentrations showed greater weld and smaller wear scar diameter.
