Steel balls, rumbled or impacted in MoS 2 or graphite, were weighed at intervals to determine the quantity of powder adhering to their surfaces. MoS 2 formed a deposit which built up to a monolayer of particles, randomly oriented; no deposit was detected for graphite. These balls were then tested in a Shell four-ball machine. Most of the MoS 2 deposit …

1) In comparison to GCr15 steel balls, the friction force of 440 C steel balls decreased by approximately 33.3%, and the wear measured on the PPI substrate and steel balls was roughly one-third and one-half of Gcr15 steel balls, respectively. Moreover, GCr15 steel balls were more prone to inducing noticeable blackening on the PPI surfaces.
