On the Influence of Friction on Velocity at a Powder-Lubricated Slider-Disk Interface: Experimentation Available to Purchase

Experiments were conducted to examine the effects of friction coefficient on sliding velocity at a slider pad/disk interface lubricated by MoS₂ powder film. The powder film was obtained by shearing compacted pellets of MoS₂ against a tungsten carbide (WC) disk and was responsible for supporting the slider pad load. The results from the experiments showed that an adverse interfacial friction coefficient leads to a decrement in the sliding velocity. Contrarily, an increased sliding velocity accompanies a favorable (i.e., smaller) friction coefficient at the WC slider pad/disk interface lubricated by the MoS₂ powder lubricant film.
