System for conducting measurements of friction of a chosen material with reduced errors. The system includes a sample holder, a bushing accommodating such holder while permitting reversible repositioning of the holder along a bushing axis, a horizontal force sensor, a vertical force sensor, a sample holder pusher and a subsystem including a linear vertical bearing (disposed in the bushing and separating the holder from the bushing) and/or a horizontally-sliding element between the rod pusher and the vertical force sensor. The subsystem is structured to reduce a rocking motion of the holder in the bushing caused by a relative motion between the sample and an auxiliary body brought in contact with the sample. The method for performing measurements with such system.

Reduction of error in testing friction and wear with the use of high-speed reciprocating motion

A nanocomposite coating that in turn extract self-replenishing (or -healing), superlubricious carbon film directly from natural gas or hydrocarbon gas in mechanical systems. The coating deposits on sealing and sliding surfaces reducing friction and wear. The result is a reduction in inefficiency, machine breakdown, and adverse environmental impact.
